We look at the division of 647812 by 86 
We're looking to find how many times 86 goes into 647812.

On to step 1:
86 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 86

Going ahead to step 2:
86 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 86

Going ahead to step 3:
647 divided by 86 is 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 602 away from 647, we end up with 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 86

Let's proceed to step 4:
If we divide 458 by 86, we get 5 and a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Deduct 430 from 458 and we're left with 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 86

On to step 5:
86 can be fit into 281 3 times, resulting in a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 753.0
The remainder is 23 after subtracting 258 from 281.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 86

On to step 6:
If we divide 232 by 86, we get 2 and a remainder of 60.
The next digit of our result is 2. 
Result so far: 7532.0
Subtract 172 from 232 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.

Going ahead to step 7:
86 can be fit into 600 6 times, resulting in a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 7532.6
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 8:
86 can be fit into 840 9 times, resulting in a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 7532.69
Deduct 774 from 840 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
86 goes into 660 7 times with a remainder of 58.
The next digit of our result is 7. 
Result so far: 7532.697
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
580 divided by 86 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 7532.6976
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
The number 86 fits into 640 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 7532.69767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 7532.697674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
The number 86 fits into 360 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 7532.6976744
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 7532.6976744 and a remainder of 1.6e-07.
