We look at the division of 749782 by 86 
Our goal is to divide 749782 by 86.

Step 1:
The number 86 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 86

Going ahead to step 2:
74 divided by 86 is 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 86

Moving on to step 3:
86 goes into 749 8 times with a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 688 from 749, we get 61.
Include the next digit (7) from the dividend after 61, then repeat: 617 / 86

Let's proceed to step 4:
When dividing 617 by 86, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Deduct 602 from 617 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 86

Step 5:
86 can be fit into 158 1 times, resulting in a remainder of 72.
The next digit of our result is 1. 
Result so far: 871.0
Subtracting 86 from 158 leaves us with 72.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 86

Moving on to step 6:
When dividing 722 by 86, we get 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 8718.0
Deduct 688 from 722 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
When dividing 340 by 86, we get 3 with a remainder of 82.
The next digit of our result is 3. 
Result so far: 8718.3
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 8:
When dividing 820 by 86, we get 9 with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 8718.39
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
86 goes into 460 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8718.395
Deduct 430 from 460 and we're left 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.

Advancing to step 10:
300 divided by 86 is 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 8718.3953
Deduct 258 from 300 and we're left 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.

Moving on to step 11:
When dividing 420 by 86, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 8718.39534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
If we divide 760 by 86, we get 8 and a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 8718.395348
Deduct 688 from 760 and we're left 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.

On to step 13:
86 goes into 720 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8718.3953488
Subtract 688 from 720 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 8718.3953488 and a remainder of 3.2e-07.
