Let's divide 865891 by 86
We want to divide 865891 by 86.

On to step 1:
8 divided by 86 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 86

Step 2:
86 goes into 86 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 86 from 86 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 86

Advancing to step 3:
When dividing 5 by 86, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 86

Step 4:
86 goes into 58 0 times with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we take 0 away from 58, we end up with 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 86

Let's proceed to step 5:
86 can be fit into 589 6 times, resulting in a remainder of 73.
The next digit of our result is 6. 
Result so far: 1006.0
Subtracting 516 from 589 leaves us with 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 86

Moving on to step 6:
When dividing 731 by 86, we get 8 with a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 10068.0
Deduct 688 from 731 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
If we divide 430 by 86, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 10068.5
Subtract 430 from 430 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 86, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10068.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 86 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10068.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 10068.5 with a remaining 0.0.
