Let's divide 53406960 by 991
Our goal is to divide 53406960 by 991.

Step 1:
991 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 991

On to step 2:
991 goes into 53 0 times with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 991

On to step 3:
If we divide 534 by 991, we get 0 and a remainder of 534.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 534 and we're left with 534.
Grab the next digit (0) from the dividend, add it to 534, then carry on: 5340 / 991

Going ahead to step 4:
991 goes into 5340 5 times with a remainder of 385.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 4955 from 5340 leaves us with 385.
Grab the next digit (6) from the dividend, add it to 385, then carry on: 3856 / 991

Advancing to step 5:
991 can be fit into 3856 3 times, resulting in a remainder of 883.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Deduct 2973 from 3856 and we're left with 883.
Bring next digit (9) of the dividend behind the 883 and repeat the process: 8839 / 991

Moving on to step 6:
8839 divided by 991 is 8 with a remainder of 911.
Record the quotient 8 as the next digit in the result. 
Result so far: 538.0
Subtracting 7928 from 8839 leaves us with 911.
Take the next digit (6) from the dividend and append it to 911, then repeat: 9116 / 991

Going ahead to step 7:
When dividing 9116 by 991, we get 9 with a remainder of 197.
The next digit of our result is 9. 
Result so far: 5389.0
Deduct 8919 from 9116 and we're left with 197.
Include the next digit (0) from the dividend after 197, then repeat: 1970 / 991

Step 8:
The number 991 fits into 1970 1 times, leaving a remainder of 979.
The next digit of our result is 1. 
Result so far: 53891.0
If we take 991 away from 1970, we end up with 979.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9790, and continue the process.

On to step 9:
The number 991 fits into 9790 9 times, leaving a remainder of 871.
Put 9 as the next digit of the answer. 
Result so far: 53891.9
The remainder is 871 after subtracting 8919 from 9790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8710, and continue the process.

Advancing to step 10:
If we divide 8710 by 991, we get 8 and a remainder of 782.
Record the quotient 8 as the next digit in the result. 
Result so far: 53891.98
If we subtract 7928 from 8710, we get 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Going ahead to step 11:
991 can be fit into 7820 7 times, resulting in a remainder of 883.
Use 7 as the next digit of our solution. 
Result so far: 53891.987
If we take 6937 away from 7820, we end up with 883.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8830, and continue the process.

Advancing to step 12:
If we divide 8830 by 991, we get 8 and a remainder of 902.
Record the quotient 8 as the next digit in the result. 
Result so far: 53891.9878
Subtracting 7928 from 8830 leaves us with 902.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9020, and continue the process.

On to step 13:
991 goes into 9020 9 times with a remainder of 101.
The number 9 becomes the next digit in our result. 
Result so far: 53891.98789
Subtract 8919 from 9020 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 14:
991 goes into 1010 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 53891.987891
Subtract 991 from 1010 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 15:
If we divide 190 by 991, we get 0 and a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 53891.987891
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 16:
991 can be fit into 1900 1 times, resulting in a remainder of 909.
Write down 1 as next digit of the result. 
Result so far: 53891.98789101
The remainder is 909 after subtracting 991 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9090, and continue the process.

In conclusion, the division gives 53891.98789101 with a balance of 9.09e-07.
