We look at the division of 851130 by 87 
We're looking to find how many times 87 goes into 851130.

Going ahead to step 1:
When dividing 8 by 87, we get 0 with 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.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 87

Going ahead to step 2:
When dividing 85 by 87, we get 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 87

Let's proceed to step 3:
The number 87 fits into 851 9 times, leaving a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 783 from 851, we get 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 87

On to step 4:
87 can be fit into 681 7 times, resulting in a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 97.0
The remainder is 72 after subtracting 609 from 681.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 87

Moving on to step 5:
87 goes into 723 8 times with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 978.0
Subtract 696 from 723 to get 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 87

Going ahead to step 6:
When dividing 270 by 87, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 9783.0
Deduct 261 from 270 and we're left with 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 7:
90 divided by 87 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 9783.1
If we subtract 87 from 90, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
30 divided by 87 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 9783.1
Subtracting 0 from 30 leaves us with 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:
87 can be fit into 300 3 times, resulting in a remainder of 39.
The next digit of our result is 3. 
Result so far: 9783.103
If we subtract 261 from 300, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 10:
If we divide 390 by 87, we get 4 and a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 9783.1034
If we take 348 away from 390, we end up with 42.
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:
87 can be fit into 420 4 times, resulting in a remainder of 72.
The next digit of our result is 4. 
Result so far: 9783.10344
Subtracting 348 from 420 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 9783.10344, with a leftover of 7.2e-05.
