We divide 664031 by 86
We want to figure out the number of times 664031 can be divided by 86.

Let's proceed to step 1:
The number 86 fits into 6 0 times, leaving 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.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 86

Step 2:
If we divide 66 by 86, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 86

Step 3:
664 divided by 86 is 7 with a remainder of 62.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 62 after subtracting 602 from 664.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 86

Let's proceed to step 4:
If we divide 620 by 86, we get 7 and a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtract 602 from 620 to get 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 86

Let's proceed to step 5:
183 divided by 86 is 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 772.0
Subtract 172 from 183 to get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 86

On to step 6:
When dividing 111 by 86, we get 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 7721.0
If we subtract 86 from 111, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
86 can be fit into 250 2 times, resulting in a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 7721.2
Subtract 172 from 250 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 8:
780 divided by 86 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 7721.29
The remainder is 6 after subtracting 774 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
86 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 7721.29
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
If we divide 600 by 86, we get 6 and a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 7721.2906
If we take 516 away from 600, we end up 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.

Let's proceed to step 11:
If we divide 840 by 86, we get 9 and a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 7721.29069
If we take 774 away from 840, we end up 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 12:
When dividing 660 by 86, we get 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 7721.290697
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 13:
When dividing 580 by 86, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 7721.2906976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
If we divide 640 by 86, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 7721.29069767
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.

The final outcome is 7721.29069767, with a leftover of 3.8e-08.
