51240340 divided by 991 
Our goal is to divide 51240340 by 991.

Advancing to step 1:
991 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 991

On to step 2:
991 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 991

On to step 3:
The number 991 fits into 512 0 times, leaving a remainder of 512.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 512 leaves us with 512.
Append the next digit (4) from the dividend to 512 and continue with: 5124 / 991

Advancing to step 4:
5124 divided by 991 is 5 with a remainder of 169.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 4955 away from 5124, we end up with 169.
Append the next digit (0) from the dividend to 169 and continue with: 1690 / 991

Advancing to step 5:
If we divide 1690 by 991, we get 1 and a remainder of 699.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
The remainder is 699 after subtracting 991 from 1690.
Take the next digit (3) from the dividend and append it to 699, then repeat: 6993 / 991

Step 6:
6993 divided by 991 is 7 with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 517.0
Subtract 6937 from 6993 to get 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 991

Let's proceed to step 7:
991 can be fit into 564 0 times, resulting in a remainder of 564.
Put 0 as the next digit of the answer. 
Result so far: 5170.0
If we take 0 away from 564, we end up with 564.
Take the next digit (0) from the dividend and append it to 564, then repeat: 5640 / 991

Let's proceed to step 8:
When dividing 5640 by 991, we get 5 with a remainder of 685.
Write down 5 as next digit of the result. 
Result so far: 51705.0
Subtracting 4955 from 5640 leaves us with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 9:
The number 991 fits into 6850 6 times, leaving a remainder of 904.
The next digit of our result is 6. 
Result so far: 51705.6
Subtracting 5946 from 6850 leaves us with 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Let's proceed to step 10:
When dividing 9040 by 991, we get 9 with a remainder of 121.
Write down 9 as next digit of the result. 
Result so far: 51705.69
If we take 8919 away from 9040, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 11:
991 can be fit into 1210 1 times, resulting in a remainder of 219.
Record the quotient 1 as the next digit in the result. 
Result so far: 51705.691
If we subtract 991 from 1210, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Step 12:
991 goes into 2190 2 times with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 51705.6912
If we subtract 1982 from 2190, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 13:
The number 991 fits into 2080 2 times, leaving a remainder of 98.
Write down 2 as next digit of the result. 
Result so far: 51705.69122
The remainder is 98 after subtracting 1982 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The final outcome is 51705.69122, with a leftover of 9.8e-05.
