We're dividing 86397568 by 747 
We want to figure out the number of times 86397568 can be divided by 747.

On to step 1:
When dividing 8 by 747, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 747

On to step 2:
When dividing 86 by 747, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Include the next digit (3) from the dividend after 86, then repeat: 863 / 747

Going ahead to step 3:
If we divide 863 by 747, we get 1 and a remainder of 116.
The next digit of our result is 1. 
Result so far: 1.0
If we take 747 away from 863, we end up with 116.
Fetch the next digit (9) from the dividend, attach it to 116 and continue: 1169 / 747

On to step 4:
If we divide 1169 by 747, we get 1 and a remainder of 422.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 422 after subtracting 747 from 1169.
Bring next digit (7) of the dividend behind the 422 and repeat the process: 4227 / 747

Moving on to step 5:
When dividing 4227 by 747, we get 5 with a remainder of 492.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtracting 3735 from 4227 leaves us with 492.
Fetch the next digit (5) from the dividend, attach it to 492 and continue: 4925 / 747

Step 6:
The number 747 fits into 4925 6 times, leaving a remainder of 443.
Write down 6 as next digit of the result. 
Result so far: 1156.0
The remainder is 443 after subtracting 4482 from 4925.
Fetch the next digit (6) from the dividend, attach it to 443 and continue: 4436 / 747

Going ahead to step 7:
The number 747 fits into 4436 5 times, leaving a remainder of 701.
Write down 5 as next digit of the result. 
Result so far: 11565.0
Subtract 3735 from 4436 to get 701.
Take the next digit (8) from the dividend and append it to 701, then repeat: 7018 / 747

On to step 8:
7018 divided by 747 is 9 with a remainder of 295.
Record the quotient 9 as the next digit in the result. 
Result so far: 115659.0
If we subtract 6723 from 7018, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 9:
747 can be fit into 2950 3 times, resulting in a remainder of 709.
Record the quotient 3 as the next digit in the result. 
Result so far: 115659.3
Subtracting 2241 from 2950 leaves us with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Step 10:
747 goes into 7090 9 times with a remainder of 367.
Write down 9 as next digit of the result. 
Result so far: 115659.39
Subtracting 6723 from 7090 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 11:
If we divide 3670 by 747, we get 4 and a remainder of 682.
The next digit of our result is 4. 
Result so far: 115659.394
Deduct 2988 from 3670 and we're left with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Let's proceed to step 12:
The number 747 fits into 6820 9 times, leaving a remainder of 97.
Record the quotient 9 as the next digit in the result. 
Result so far: 115659.3949
Subtracting 6723 from 6820 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 13:
The number 747 fits into 970 1 times, leaving a remainder of 223.
The next digit of our result is 1. 
Result so far: 115659.39491
Deduct 747 from 970 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 14:
The number 747 fits into 2230 2 times, leaving a remainder of 736.
The next digit of our result is 2. 
Result so far: 115659.394912
If we take 1494 away from 2230, we end up with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 15:
747 can be fit into 7360 9 times, resulting in a remainder of 637.
Record the quotient 9 as the next digit in the result. 
Result so far: 115659.3949129
Subtract 6723 from 7360 to get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Step 16:
6370 divided by 747 is 8 with a remainder of 394.
Use 8 as the next digit of our solution. 
Result so far: 115659.39491298
Deduct 5976 from 6370 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Our division results in 115659.39491298 with a remaining 3.94e-07.
