We look at the division of 668433 by 86 
Let's see how many times 86 fits into 668433.

On to step 1:
86 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 86

Let's proceed to step 2:
86 goes into 66 0 times with 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.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 86

Advancing to step 3:
When dividing 668 by 86, we get 7 with a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 602 from 668 and we're left with 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 86

Moving on to step 4:
86 goes into 664 7 times with a remainder of 62.
The next digit of our result is 7. 
Result so far: 77.0
Subtract 602 from 664 to get 62.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 86

Step 5:
86 can be fit into 623 7 times, resulting in a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 777.0
If we take 602 away from 623, we end up with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 86

Going ahead to step 6:
If we divide 213 by 86, we get 2 and a remainder of 41.
The next digit of our result is 2. 
Result so far: 7772.0
If we take 172 away from 213, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
86 goes into 410 4 times with a remainder of 66.
The next digit of our result is 4. 
Result so far: 7772.4
If we subtract 344 from 410, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The next digit of our result is 7. 
Result so far: 7772.47
Subtracting 602 from 660 leaves us 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.

Step 9:
If we divide 580 by 86, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 7772.476
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
When dividing 640 by 86, we get 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 7772.4767
If we take 602 away from 640, we end up with 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 11:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 7772.47674
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
86 can be fit into 360 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7772.476744
The remainder is 16 after subtracting 344 from 360.
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 7772.476744 and a remainder of 1.6e-06.
