We're dividing 491360 by 51 
Let's see how many times 51 fits into 491360.

Going ahead to step 1:
51 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 51

Going ahead to step 2:
If we divide 49 by 51, we get 0 and a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 51

Step 3:
The number 51 fits into 491 9 times, leaving a remainder of 32.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 459 from 491 to get 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 51

Moving on to step 4:
If we divide 323 by 51, we get 6 and a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 17 after subtracting 306 from 323.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 51

On to step 5:
51 can be fit into 176 3 times, resulting in a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 963.0
If we take 153 away from 176, we end up with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 51

Moving on to step 6:
The number 51 fits into 230 4 times, leaving a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 9634.0
Subtract 204 from 230 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.

Step 7:
If we divide 260 by 51, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 9634.5
If we subtract 255 from 260, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
If we divide 50 by 51, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 9634.5
Subtract 0 from 50 to 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 9:
51 goes into 500 9 times with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 9634.509
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.

Step 10:
410 divided by 51 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 9634.5098
Deduct 408 from 410 and we're left 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.

Going ahead to step 11:
20 divided by 51 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9634.5098
If we subtract 0 from 20, we 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.

Advancing to step 12:
When dividing 200 by 51, we get 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 9634.509803
If we take 153 away from 200, we end up 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.

Let's proceed to step 13:
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: 9634.5098039
Subtract 459 from 470 to 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.

On to step 14:
51 goes into 110 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 9634.50980392
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 9634.50980392 and a remainder of 8e-09.
