807152 ÷ 51 
We want to figure out the number of times 807152 can be divided by 51.

Going ahead to step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 51

Step 2:
If we divide 80 by 51, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 51 from 80 and we're left with 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 51

Going ahead to step 3:
51 can be fit into 297 5 times, resulting in a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 42 after subtracting 255 from 297.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 51

Step 4:
The number 51 fits into 421 8 times, leaving a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 158.0
If we take 408 away from 421, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 51

Moving on to step 5:
The number 51 fits into 135 2 times, leaving a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 1582.0
The remainder is 33 after subtracting 102 from 135.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 51

Let's proceed to step 6:
51 can be fit into 332 6 times, resulting in a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 15826.0
If we subtract 306 from 332, we 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.

Moving on to step 7:
When dividing 260 by 51, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 15826.5
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.

On to step 8:
50 divided by 51 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 15826.5
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
500 divided by 51 is 9 with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 15826.509
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
The number 51 fits into 410 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 15826.5098
Subtract 408 from 410 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
If we divide 20 by 51, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15826.5098
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
200 divided by 51 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 15826.509803
Deduct 153 from 200 and we're left 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.

Moving on to step 13:
The number 51 fits into 470 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 15826.5098039
Subtracting 459 from 470 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
The number 51 fits into 110 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 15826.50980392
Subtracting 102 from 110 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 15826.50980392, with a leftover of 8e-09.
