We look at the division of 691171 by 51 
We're looking to find how many times 51 goes into 691171.

Let's proceed to step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 51

Going ahead to step 2:
If we divide 69 by 51, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 51 away from 69, we end up with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 51

Advancing to step 3:
181 divided by 51 is 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 153 from 181 and we're left with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 51

Advancing to step 4:
51 goes into 281 5 times with a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 135.0
If we subtract 255 from 281, we get 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 51

Moving on to step 5:
When dividing 267 by 51, we get 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 1355.0
If we subtract 255 from 267, we get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 51

Let's proceed to step 6:
If we divide 121 by 51, we get 2 and a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 13552.0
Deduct 102 from 121 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
If we divide 190 by 51, we get 3 and a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 13552.3
If we take 153 away from 190, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 13552.37
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
51 can be fit into 130 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 13552.372
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
If we divide 280 by 51, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 13552.3725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 13552.37254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
The number 51 fits into 460 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 13552.372549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
51 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 13552.372549
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.

Step 14:
The number 51 fits into 100 1 times, leaving a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 13552.37254901
Subtract 51 from 100 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The quotient of the division is 13552.37254901, and the remainder is 4.9e-08.
