664596 divided by 86 
We want to divide 664596 by 86.

Let's proceed to step 1:
When dividing 6 by 86, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 86

On to step 2:
When dividing 66 by 86, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 86

Step 3:
86 goes into 664 7 times with a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 602 away from 664, we end up with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 86

Going ahead to step 4:
The number 86 fits into 625 7 times, leaving a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Deduct 602 from 625 and we're left with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 86

Moving on to step 5:
86 goes into 239 2 times with a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 772.0
Deduct 172 from 239 and we're left with 67.
Append the next digit (6) from the dividend to 67 and continue with: 676 / 86

Step 6:
When dividing 676 by 86, we get 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 7727.0
Subtracting 602 from 676 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 7:
The number 86 fits into 740 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 7727.8
Deduct 688 from 740 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
If we divide 520 by 86, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 7727.86
Subtract 516 from 520 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
86 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7727.86
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 86 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 7727.8604
If we take 344 away from 400, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
When dividing 560 by 86, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 7727.86046
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.

On to step 12:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 7727.860465
If we take 430 away from 440, we end up 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 13:
86 can be fit into 100 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 7727.8604651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
When dividing 140 by 86, we get 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 7727.86046511
Deduct 86 from 140 and we're left 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 quotient of the division is 7727.86046511, and the remainder is 5.4e-08.
