We look at the division of 492390 by 51 
Our goal is to divide 492390 by 51.

Advancing to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 51

Moving on to step 2:
The number 51 fits into 49 0 times, leaving a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (2) of the dividend behind the 49 and repeat the process: 492 / 51

Going ahead to step 3:
51 goes into 492 9 times with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 459 from 492 to get 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 51

Going ahead to step 4:
If we divide 333 by 51, we get 6 and a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we take 306 away from 333, we end up with 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 51

Going ahead to step 5:
If we divide 279 by 51, we get 5 and a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 965.0
If we subtract 255 from 279, we get 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 51

Step 6:
If we divide 240 by 51, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 9654.0
Subtract 204 from 240 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
51 can be fit into 360 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 9654.7
Subtracting 357 from 360 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
When dividing 30 by 51, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9654.7
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
The number 51 fits into 300 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 9654.705
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
51 goes into 450 8 times with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 9654.7058
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
When dividing 420 by 51, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 9654.70588
If we subtract 408 from 420, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 9654.70588, and the remainder is 1.2e-05.
