We divide 495390 by 51
Let's see how many times 51 fits into 495390.

Moving on to step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 51

Step 2:
51 goes into 49 0 times with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 51

Moving on to step 3:
If we divide 495 by 51, we get 9 and a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 459 away from 495, we end up with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 51

On to step 4:
The number 51 fits into 363 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
If we subtract 357 from 363, we get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 51

On to step 5:
If we divide 69 by 51, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 971.0
If we take 51 away from 69, we end up with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 51

Moving on to step 6:
When dividing 180 by 51, we get 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 9713.0
The remainder is 27 after subtracting 153 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
If we divide 270 by 51, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 9713.5
If we subtract 255 from 270, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
The number 51 fits into 150 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 9713.52
If we take 102 away from 150, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
51 goes into 480 9 times with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 9713.529
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
210 divided by 51 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 9713.5294
If we subtract 204 from 210, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
60 divided by 51 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 9713.52941
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
When dividing 90 by 51, we get 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 9713.529411
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 9713.529411, with a leftover of 3.9e-06.
