We're dividing 491513 by 51 
We're looking to find how many times 51 goes into 491513.

Going ahead to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 51

Advancing to step 2:
51 can be fit into 49 0 times, resulting in a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 51

Going ahead to step 3:
51 can be fit into 491 9 times, resulting in a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 459 from 491 to get 32.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 51

Let's proceed to step 4:
325 divided by 51 is 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 306 from 325, we get 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 51

Advancing to step 5:
The number 51 fits into 191 3 times, leaving a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 963.0
If we subtract 153 from 191, we get 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 51

Advancing to step 6:
When dividing 383 by 51, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 9637.0
Subtract 357 from 383 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.

On to step 7:
When dividing 260 by 51, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9637.5
If we take 255 away from 260, we end up 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.

Advancing 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: 9637.5
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.

Advancing to step 9:
If we divide 500 by 51, we get 9 and a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 9637.509
The remainder is 41 after subtracting 459 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
When dividing 410 by 51, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 9637.5098
If we take 408 away from 410, we end up with 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: 9637.5098
Subtracting 0 from 20 leaves us 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.

Advancing to step 12:
The number 51 fits into 200 3 times, leaving a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 9637.509803
Subtracting 153 from 200 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 13:
When dividing 470 by 51, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 9637.5098039
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.

Going ahead to step 14:
51 can be fit into 110 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 9637.50980392
Subtract 102 from 110 to 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.

After the division, we end up with 9637.50980392 and a remainder of 8e-09.
