51192708 ÷ 993 
We want to figure out the number of times 51192708 can be divided by 993.

Going ahead to step 1:
When dividing 5 by 993, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 993

On to step 2:
993 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 993

Advancing to step 3:
511 divided by 993 is 0 with a remainder of 511.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 511 to get 511.
Include the next digit (9) from the dividend after 511, then repeat: 5119 / 993

Advancing to step 4:
When dividing 5119 by 993, we get 5 with a remainder of 154.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 154 after subtracting 4965 from 5119.
Append the next digit (2) from the dividend to 154 and continue with: 1542 / 993

Moving on to step 5:
1542 divided by 993 is 1 with a remainder of 549.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtracting 993 from 1542 leaves us with 549.
Fetch the next digit (7) from the dividend, attach it to 549 and continue: 5497 / 993

Step 6:
When dividing 5497 by 993, we get 5 with a remainder of 532.
Record the quotient 5 as the next digit in the result. 
Result so far: 515.0
Subtracting 4965 from 5497 leaves us with 532.
Fetch the next digit (0) from the dividend, attach it to 532 and continue: 5320 / 993

Going ahead to step 7:
993 can be fit into 5320 5 times, resulting in a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 5155.0
If we subtract 4965 from 5320, we get 355.
Include the next digit (8) from the dividend after 355, then repeat: 3558 / 993

Going ahead to step 8:
When dividing 3558 by 993, we get 3 with a remainder of 579.
Put 3 as the next digit of the answer. 
Result so far: 51553.0
If we subtract 2979 from 3558, we get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 9:
When dividing 5790 by 993, we get 5 with a remainder of 825.
The next digit of our result is 5. 
Result so far: 51553.5
If we subtract 4965 from 5790, we get 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

Going ahead to step 10:
993 can be fit into 8250 8 times, resulting in a remainder of 306.
Write down 8 as next digit of the result. 
Result so far: 51553.58
Deduct 7944 from 8250 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 11:
993 goes into 3060 3 times with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 51553.583
Subtract 2979 from 3060 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 12:
When dividing 810 by 993, we get 0 with a remainder of 810.
Use 0 as the next digit of our solution. 
Result so far: 51553.583
Deduct 0 from 810 and we're left with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 13:
If we divide 8100 by 993, we get 8 and a remainder of 156.
The number 8 becomes the next digit in our result. 
Result so far: 51553.58308
If we take 7944 away from 8100, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 14:
1560 divided by 993 is 1 with a remainder of 567.
Write down 1 as next digit of the result. 
Result so far: 51553.583081
If we take 993 away from 1560, we end up with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Step 15:
993 goes into 5670 5 times with a remainder of 705.
Record the quotient 5 as the next digit in the result. 
Result so far: 51553.5830815
If we subtract 4965 from 5670, we get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Step 16:
993 can be fit into 7050 7 times, resulting in a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 51553.58308157
The remainder is 99 after subtracting 6951 from 7050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Our division results in 51553.58308157 with a remaining 9.9e-08.
