We look at the division of 812488 by 51 
We want to divide 812488 by 51.

Moving on to step 1:
8 divided by 51 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 51

Let's proceed to step 2:
51 goes into 81 1 times with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 81 to get 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 51

Moving on to step 3:
If we divide 302 by 51, we get 5 and a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 255 from 302 and we're left with 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 51

Moving on to step 4:
51 can be fit into 474 9 times, resulting in a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtract 459 from 474 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 51

Advancing to step 5:
When dividing 158 by 51, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 1593.0
Subtract 153 from 158 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 51

Advancing to step 6:
58 divided by 51 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 15931.0
Deduct 51 from 58 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
When dividing 70 by 51, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 15931.1
If we take 51 away from 70, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
51 goes into 190 3 times with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 15931.13
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
51 goes into 370 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 15931.137
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
If we divide 130 by 51, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 15931.1372
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
The number 51 fits into 280 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 15931.13725
Subtracting 255 from 280 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 15931.137254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
If we divide 460 by 51, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 15931.1372549
Subtracting 459 from 460 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
The number 51 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15931.1372549
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 15931.1372549 and a remainder of 1e-08.
