We look at the division of 626790 by 86 
Our goal is to divide 626790 by 86.

Going ahead to step 1:
86 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 86

On to step 2:
86 can be fit into 62 0 times, resulting in a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 86

Let's proceed to step 3:
86 goes into 626 7 times with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 602 from 626 leaves us with 24.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 86

Moving on to step 4:
If we divide 247 by 86, we get 2 and a remainder of 75.
Write down 2 as next digit of the result. 
Result so far: 72.0
The remainder is 75 after subtracting 172 from 247.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 86

Let's proceed to step 5:
If we divide 759 by 86, we get 8 and a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 728.0
Subtract 688 from 759 to get 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 86

Advancing to step 6:
The number 86 fits into 710 8 times, leaving a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 7288.0
Subtract 688 from 710 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
If we divide 220 by 86, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 7288.2
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
When dividing 480 by 86, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 7288.25
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
86 goes into 500 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 7288.255
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 7288.255 with a remainder of 0.007.
