We're dividing 75521305 by 860 
We want to divide 75521305 by 860.

Going ahead to step 1:
The number 860 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 860

Let's proceed to step 2:
If we divide 75 by 860, we get 0 and a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Append the next digit (5) from the dividend to 75 and continue with: 755 / 860

Moving on to step 3:
When dividing 755 by 860, we get 0 with a remainder of 755.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 755 after subtracting 0 from 755.
Bring next digit (2) of the dividend behind the 755 and repeat the process: 7552 / 860

Step 4:
7552 divided by 860 is 8 with a remainder of 672.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 6880 from 7552 to get 672.
Take the next digit (1) from the dividend and append it to 672, then repeat: 6721 / 860

Step 5:
860 can be fit into 6721 7 times, resulting in a remainder of 701.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtracting 6020 from 6721 leaves us with 701.
Take the next digit (3) from the dividend and append it to 701, then repeat: 7013 / 860

Step 6:
860 goes into 7013 8 times with a remainder of 133.
Write down 8 as next digit of the result. 
Result so far: 878.0
The remainder is 133 after subtracting 6880 from 7013.
Take the next digit (0) from the dividend and append it to 133, then repeat: 1330 / 860

Let's proceed to step 7:
When dividing 1330 by 860, we get 1 with a remainder of 470.
Write down 1 as next digit of the result. 
Result so far: 8781.0
Subtracting 860 from 1330 leaves us with 470.
Grab the next digit (5) from the dividend, add it to 470, then carry on: 4705 / 860

Let's proceed to step 8:
The number 860 fits into 4705 5 times, leaving a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 87815.0
If we take 4300 away from 4705, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 9:
When dividing 4050 by 860, we get 4 with a remainder of 610.
The next digit of our result is 4. 
Result so far: 87815.4
Subtracting 3440 from 4050 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 10:
If we divide 6100 by 860, we get 7 and a remainder of 80.
Use 7 as the next digit of our solution. 
Result so far: 87815.47
Subtract 6020 from 6100 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
When dividing 800 by 860, we get 0 with a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 87815.47
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 12:
860 goes into 8000 9 times with a remainder of 260.
Write down 9 as next digit of the result. 
Result so far: 87815.4709
Subtract 7740 from 8000 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 13:
2600 divided by 860 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 87815.47093
If we subtract 2580 from 2600, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
When dividing 200 by 860, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 87815.47093
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 15:
The number 860 fits into 2000 2 times, leaving a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 87815.4709302
The remainder is 280 after subtracting 1720 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
The number 860 fits into 2800 3 times, leaving a remainder of 220.
Record the quotient 3 as the next digit in the result. 
Result so far: 87815.47093023
Deduct 2580 from 2800 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Our division results in 87815.47093023 with a remaining 2.2e-07.
