We look at the division of 787900 by 51 
We're looking to find how many times 51 goes into 787900.

Moving on to step 1:
51 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 51

On to step 2:
78 divided by 51 is 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 78 to get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 51

Let's proceed to step 3:
When dividing 277 by 51, we get 5 with a remainder of 22.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 22 after subtracting 255 from 277.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 51

On to step 4:
51 can be fit into 229 4 times, resulting in a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
The remainder is 25 after subtracting 204 from 229.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 51

On to step 5:
250 divided by 51 is 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 1544.0
Deduct 204 from 250 and we're left with 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 51

On to step 6:
When dividing 460 by 51, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 15449.0
Subtracting 459 from 460 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
51 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 15449.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
51 can be fit into 100 1 times, resulting in a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 15449.01
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
490 divided by 51 is 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 15449.019
If we take 459 away from 490, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 10:
310 divided by 51 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 15449.0196
If we take 306 away from 310, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
51 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 15449.0196
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
400 divided by 51 is 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 15449.019607
Deduct 357 from 400 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 13:
When dividing 430 by 51, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 15449.0196078
If we take 408 away from 430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
51 goes into 220 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 15449.01960784
The remainder is 16 after subtracting 204 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 15449.01960784, with a leftover of 1.6e-08.
