We're dividing 987749 by 51 
Our goal is to divide 987749 by 51.

Step 1:
If we divide 9 by 51, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 51

Step 2:
51 goes into 98 1 times with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 51 away from 98, we end up with 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 51

Going ahead to step 3:
477 divided by 51 is 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 18 after subtracting 459 from 477.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 51

Going ahead to step 4:
If we divide 187 by 51, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 193.0
Subtract 153 from 187 to get 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 51

Step 5:
51 goes into 344 6 times with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 1936.0
The remainder is 38 after subtracting 306 from 344.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 51

On to step 6:
When dividing 389 by 51, we get 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 19367.0
If we subtract 357 from 389, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
The number 51 fits into 320 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 19367.6
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
When dividing 140 by 51, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 19367.62
Subtracting 102 from 140 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
380 divided by 51 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 19367.627
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
The number 51 fits into 230 4 times, leaving a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 19367.6274
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
The number 51 fits into 260 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 19367.62745
The remainder is 5 after subtracting 255 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
50 divided by 51 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 19367.62745
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
When dividing 500 by 51, we get 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 19367.6274509
If we take 459 away from 500, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 14:
410 divided by 51 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 19367.62745098
Subtracting 408 from 410 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 19367.62745098, with a leftover of 2e-09.
