391655 ÷ 51 
We want to figure out the number of times 391655 can be divided by 51.

Moving on to step 1:
3 divided by 51 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 51

Let's proceed to step 2:
51 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 51

Going ahead to step 3:
391 divided by 51 is 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 357 from 391 and we're left with 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 51

Let's proceed to step 4:
51 can be fit into 346 6 times, resulting in a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Deduct 306 from 346 and we're left with 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 51

On to step 5:
51 goes into 405 7 times with a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 767.0
If we take 357 away from 405, we end up with 48.
Grab the next digit (5) from the dividend, add it to 48, then carry on: 485 / 51

On to step 6:
51 can be fit into 485 9 times, resulting in a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 7679.0
Subtract 459 from 485 to get 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 7:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 7679.5
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
50 divided by 51 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7679.5
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 7679.509
Subtracting 459 from 500 leaves us 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.

Advancing to step 10:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 7679.5098
If we subtract 408 from 410, we 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.

Moving on to step 11:
51 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7679.5098
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
If we divide 200 by 51, we get 3 and a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 7679.509803
The remainder is 47 after subtracting 153 from 200.
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 13:
If we divide 470 by 51, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 7679.5098039
If we subtract 459 from 470, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
51 can be fit into 110 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 7679.50980392
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 7679.50980392, and the remainder is 8e-09.
