We divide 91006439 by 860
We want to divide 91006439 by 860.

Step 1:
When dividing 9 by 860, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 860

On to step 2:
When dividing 91 by 860, we get 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 860

Step 3:
If we divide 910 by 860, we get 1 and a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 860 from 910, we get 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 860

Going ahead to step 4:
500 divided by 860 is 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 500, we get 500.
Take the next digit (6) from the dividend and append it to 500, then repeat: 5006 / 860

Advancing to step 5:
860 goes into 5006 5 times with a remainder of 706.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we subtract 4300 from 5006, we get 706.
Bring next digit (4) of the dividend behind the 706 and repeat the process: 7064 / 860

On to step 6:
860 can be fit into 7064 8 times, resulting in a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 1058.0
Subtract 6880 from 7064 to get 184.
Include the next digit (3) from the dividend after 184, then repeat: 1843 / 860

Step 7:
The number 860 fits into 1843 2 times, leaving a remainder of 123.
Write down 2 as next digit of the result. 
Result so far: 10582.0
Deduct 1720 from 1843 and we're left with 123.
Fetch the next digit (9) from the dividend, attach it to 123 and continue: 1239 / 860

Let's proceed to step 8:
860 goes into 1239 1 times with a remainder of 379.
Write down 1 as next digit of the result. 
Result so far: 105821.0
Deduct 860 from 1239 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 9:
If we divide 3790 by 860, we get 4 and a remainder of 350.
The next digit of our result is 4. 
Result so far: 105821.4
If we take 3440 away from 3790, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 10:
860 goes into 3500 4 times with a remainder of 60.
The next digit of our result is 4. 
Result so far: 105821.44
Subtract 3440 from 3500 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 105821.44 with a remaining 0.06.
