We look at the division of 51210283 by 993 
Our goal is to divide 51210283 by 993.

On to step 1:
993 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 993

On to step 2:
993 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 993

Going ahead to step 3:
When dividing 512 by 993, we get 0 with a remainder of 512.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 512 leaves us with 512.
Include the next digit (1) from the dividend after 512, then repeat: 5121 / 993

Advancing to step 4:
993 goes into 5121 5 times with a remainder of 156.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 4965 from 5121, we get 156.
Take the next digit (0) from the dividend and append it to 156, then repeat: 1560 / 993

Moving on to step 5:
993 can be fit into 1560 1 times, resulting in a remainder of 567.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we take 993 away from 1560, we end up with 567.
Bring next digit (2) of the dividend behind the 567 and repeat the process: 5672 / 993

Going ahead to step 6:
993 can be fit into 5672 5 times, resulting in a remainder of 707.
The number 5 becomes the next digit in our result. 
Result so far: 515.0
If we take 4965 away from 5672, we end up with 707.
Grab the next digit (8) from the dividend, add it to 707, then carry on: 7078 / 993

Let's proceed to step 7:
The number 993 fits into 7078 7 times, leaving a remainder of 127.
Use 7 as the next digit of our solution. 
Result so far: 5157.0
The remainder is 127 after subtracting 6951 from 7078.
Include the next digit (3) from the dividend after 127, then repeat: 1273 / 993

Advancing to step 8:
If we divide 1273 by 993, we get 1 and a remainder of 280.
Record the quotient 1 as the next digit in the result. 
Result so far: 51571.0
Subtract 993 from 1273 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 9:
2800 divided by 993 is 2 with a remainder of 814.
Use 2 as the next digit of our solution. 
Result so far: 51571.2
If we subtract 1986 from 2800, we get 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Going ahead to step 10:
If we divide 8140 by 993, we get 8 and a remainder of 196.
The next digit of our result is 8. 
Result so far: 51571.28
Deduct 7944 from 8140 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 11:
The number 993 fits into 1960 1 times, leaving a remainder of 967.
Write down 1 as next digit of the result. 
Result so far: 51571.281
If we subtract 993 from 1960, we get 967.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9670, and continue the process.

Advancing to step 12:
When dividing 9670 by 993, we get 9 with a remainder of 733.
The next digit of our result is 9. 
Result so far: 51571.2819
Subtracting 8937 from 9670 leaves us with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Let's proceed to step 13:
If we divide 7330 by 993, we get 7 and a remainder of 379.
Record the quotient 7 as the next digit in the result. 
Result so far: 51571.28197
The remainder is 379 after subtracting 6951 from 7330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Going ahead to step 14:
3790 divided by 993 is 3 with a remainder of 811.
Record the quotient 3 as the next digit in the result. 
Result so far: 51571.281973
If we take 2979 away from 3790, we end up with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Let's proceed to step 15:
If we divide 8110 by 993, we get 8 and a remainder of 166.
Record the quotient 8 as the next digit in the result. 
Result so far: 51571.2819738
Deduct 7944 from 8110 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 16:
1660 divided by 993 is 1 with a remainder of 667.
Record the quotient 1 as the next digit in the result. 
Result so far: 51571.28197381
Subtract 993 from 1660 to get 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

The final result is 51571.28197381 with a remainder of 6.67e-07.
