We look at the division of 863248 by 51 
We want to figure out the number of times 863248 can be divided by 51.

Advancing to step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 51

Step 2:
86 divided by 51 is 1 with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 35 after subtracting 51 from 86.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 51

Going ahead to step 3:
353 divided by 51 is 6 with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 306 from 353 leaves us with 47.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 51

Let's proceed to step 4:
The number 51 fits into 472 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 169.0
The remainder is 13 after subtracting 459 from 472.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 51

Going ahead to step 5:
The number 51 fits into 134 2 times, leaving a remainder of 32.
The next digit of our result is 2. 
Result so far: 1692.0
Deduct 102 from 134 and we're left with 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 51

Going ahead to step 6:
If we divide 328 by 51, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 16926.0
Subtracting 306 from 328 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
51 can be fit into 220 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 16926.4
Subtracting 204 from 220 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
160 divided by 51 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 16926.43
If we take 153 away from 160, we end up 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.

On to step 9:
The number 51 fits into 70 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 16926.431
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 10:
If we divide 190 by 51, we get 3 and a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 16926.4313
Subtracting 153 from 190 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
If we divide 370 by 51, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 16926.43137
Subtract 357 from 370 to 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.

Let's proceed to step 12:
51 goes into 130 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 16926.431372
Deduct 102 from 130 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
When dividing 280 by 51, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 16926.4313725
If we take 255 away from 280, we end up 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.

Moving on to step 14:
The number 51 fits into 250 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 16926.43137254
Subtracting 204 from 250 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 16926.43137254 and a remainder of 4.6e-08.
