We look at the division of 23917792 by 991 
We're looking to find how many times 991 goes into 23917792.

Advancing to step 1:
991 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 991

Advancing to step 2:
When dividing 23 by 991, we get 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 991

Advancing to step 3:
The number 991 fits into 239 0 times, leaving a remainder of 239.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 239 to get 239.
Fetch the next digit (1) from the dividend, attach it to 239 and continue: 2391 / 991

On to step 4:
When dividing 2391 by 991, we get 2 with a remainder of 409.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 409 after subtracting 1982 from 2391.
Grab the next digit (7) from the dividend, add it to 409, then carry on: 4097 / 991

Advancing to step 5:
When dividing 4097 by 991, we get 4 with a remainder of 133.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 3964 away from 4097, we end up with 133.
Include the next digit (7) from the dividend after 133, then repeat: 1337 / 991

Going ahead to step 6:
991 goes into 1337 1 times with a remainder of 346.
Put 1 as the next digit of the answer. 
Result so far: 241.0
The remainder is 346 after subtracting 991 from 1337.
Take the next digit (9) from the dividend and append it to 346, then repeat: 3469 / 991

Going ahead to step 7:
The number 991 fits into 3469 3 times, leaving a remainder of 496.
The next digit of our result is 3. 
Result so far: 2413.0
Subtract 2973 from 3469 to get 496.
Append the next digit (2) from the dividend to 496 and continue with: 4962 / 991

Let's proceed to step 8:
991 can be fit into 4962 5 times, resulting in a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 24135.0
Subtract 4955 from 4962 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
70 divided by 991 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 24135.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
991 goes into 700 0 times with a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 24135.0
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Our division results in 24135.0 with a remaining 0.7.
