We look at the division of 837688 by 51 
Let's see how many times 51 fits into 837688.

Step 1:
8 divided by 51 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 51

Advancing to step 2:
51 can be fit into 83 1 times, resulting in a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 51 away from 83, we end up with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 51

Advancing to step 3:
If we divide 327 by 51, we get 6 and a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 306 from 327 and we're left with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 51

On to step 4:
51 can be fit into 216 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 164.0
Subtracting 204 from 216 leaves us with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 51

Let's proceed to step 5:
128 divided by 51 is 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 1642.0
Subtracting 102 from 128 leaves us with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 51

On to step 6:
When dividing 268 by 51, we get 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 16425.0
The remainder is 13 after subtracting 255 from 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
130 divided by 51 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 16425.2
Deduct 102 from 130 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
The number 51 fits into 280 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 16425.25
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
The number 51 fits into 250 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 16425.254
If we take 204 away from 250, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
When dividing 460 by 51, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 16425.2549
If we take 459 away from 460, we end up 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.

Going ahead to step 11:
10 divided by 51 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 16425.2549
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
The number 51 fits into 100 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 16425.254901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 13:
490 divided by 51 is 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 16425.2549019
Subtract 459 from 490 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 14:
51 goes into 310 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 16425.25490196
Subtract 306 from 310 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 16425.25490196 with a remainder of 4e-09.
