Let's divide 39677661 by 991
We want to divide 39677661 by 991.

Moving on to step 1:
991 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 991

Step 2:
The number 991 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 991

Moving on to step 3:
991 can be fit into 396 0 times, resulting in a remainder of 396.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 396, we get 396.
Fetch the next digit (7) from the dividend, attach it to 396 and continue: 3967 / 991

On to step 4:
The number 991 fits into 3967 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3964 away from 3967, we end up with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 991

Step 5:
If we divide 37 by 991, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 37 after subtracting 0 from 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 991

Going ahead to step 6:
If we divide 376 by 991, we get 0 and a remainder of 376.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
Subtracting 0 from 376 leaves us with 376.
Take the next digit (6) from the dividend and append it to 376, then repeat: 3766 / 991

Let's proceed to step 7:
991 can be fit into 3766 3 times, resulting in a remainder of 793.
The number 3 becomes the next digit in our result. 
Result so far: 4003.0
Deduct 2973 from 3766 and we're left with 793.
Bring next digit (1) of the dividend behind the 793 and repeat the process: 7931 / 991

Step 8:
991 can be fit into 7931 8 times, resulting in a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 40038.0
Subtract 7928 from 7931 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
The number 991 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 40038.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
If we divide 300 by 991, we get 0 and a remainder of 300.
The next digit of our result is 0. 
Result so far: 40038.0
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 40038.0, and the remainder is 0.3.
