1) user input number: 123456 -> 1+3+5

Method 1:

n = 123456

m = n // 100000
n = n % 10000
print(m)

m = n // 1000
n = n % 100
print(m)

m = n // 10
n = n % 1
print(m)

Method 2:

n = 123456
div = 100000
total = 0

while div > 0:
    m = n // div
    n = n % (div //10)
    total += m
    print(m)
    div = div // 100

print(f'total = {total}')

Output:

1

print(m)

n = n % 1000
m = n // 100
print(m)

n = n % 10
m = n // 1
print(m)

Method 2:

n = 123456
