We look at the division of 691940 by 51 
Our goal is to divide 691940 by 51.

On to step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 51

Let's proceed to step 2:
51 goes into 69 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 51 from 69, we get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 51

Let's proceed to step 3:
The number 51 fits into 181 3 times, leaving a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 153 from 181 leaves us with 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 51

Going ahead to step 4:
289 divided by 51 is 5 with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Deduct 255 from 289 and we're left with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 51

Moving on to step 5:
51 goes into 344 6 times with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 1356.0
If we take 306 away from 344, we end up with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 51

Advancing to step 6:
When dividing 380 by 51, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 13567.0
Deduct 357 from 380 and we're left with 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 7:
230 divided by 51 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 13567.4
Deduct 204 from 230 and we're left with 26.
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 8:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 13567.45
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.

Moving on to step 9:
50 divided by 51 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 13567.45
If we subtract 0 from 50, we get 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 10:
500 divided by 51 is 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 13567.4509
If we subtract 459 from 500, we get 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 11:
51 can be fit into 410 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 13567.45098
Subtract 408 from 410 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
When dividing 20 by 51, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 13567.45098
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
When dividing 200 by 51, we get 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 13567.4509803
If we subtract 153 from 200, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
If we divide 470 by 51, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 13567.45098039
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 13567.45098039 with a remainder of 1.1e-08.
