We're dividing 86386524 by 86 
We want to figure out the number of times 86386524 can be divided by 86.

On to step 1:
86 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 86

Going ahead to step 2:
When dividing 86 by 86, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 86 away from 86, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 86

Step 3:
When dividing 3 by 86, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 86

Advancing to step 4:
When dividing 38 by 86, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 100.0
The remainder is 38 after subtracting 0 from 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 86

Going ahead to step 5:
If we divide 386 by 86, we get 4 and a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 1004.0
Deduct 344 from 386 and we're left with 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 86

Advancing to step 6:
86 goes into 425 4 times with a remainder of 81.
The number 4 becomes the next digit in our result. 
Result so far: 10044.0
Deduct 344 from 425 and we're left with 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 86

Advancing to step 7:
If we divide 812 by 86, we get 9 and a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 100449.0
If we subtract 774 from 812, we get 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 86

Moving on to step 8:
384 divided by 86 is 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 1004494.0
Deduct 344 from 384 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 86, we get 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 1004494.4
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
86 goes into 560 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 1004494.46
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
When dividing 440 by 86, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1004494.465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
When dividing 100 by 86, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1004494.4651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
If we divide 140 by 86, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 1004494.46511
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 1004494.46511, with a leftover of 5.4e-05.
