691975 ÷ 51 
Our goal is to divide 691975 by 51.

On to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 51

Advancing to step 2:
69 divided by 51 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 18 after subtracting 51 from 69.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 51

Moving on to step 3:
51 can be fit into 181 3 times, resulting in a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 153 from 181, we get 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 51

Moving on to step 4:
289 divided by 51 is 5 with a remainder of 34.
The next digit of our result is 5. 
Result so far: 135.0
Deduct 255 from 289 and we're left with 34.
Grab the next digit (7) from the dividend, add it to 34, then carry on: 347 / 51

Let's proceed to step 5:
When dividing 347 by 51, we get 6 with a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 1356.0
Deduct 306 from 347 and we're left with 41.
Take the next digit (5) from the dividend and append it to 41, then repeat: 415 / 51

Advancing to step 6:
415 divided by 51 is 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 13568.0
Deduct 408 from 415 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 51, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 13568.1
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
The number 51 fits into 190 3 times, leaving a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 13568.13
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
51 goes into 370 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 13568.137
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 10:
130 divided by 51 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 13568.1372
The remainder is 28 after subtracting 102 from 130.
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 11:
The number 51 fits into 280 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 13568.13725
Deduct 255 from 280 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
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: 13568.137254
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
If we divide 460 by 51, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 13568.1372549
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 14:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13568.1372549
Subtract 0 from 10 to 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.

The quotient of the division is 13568.1372549, and the remainder is 1e-08.
