8612070 divided by 717 
Our goal is to divide 8612070 by 717.

Moving on to step 1:
If we divide 8 by 717, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 717

Going ahead to step 2:
86 divided by 717 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 717

Going ahead to step 3:
The number 717 fits into 861 1 times, leaving a remainder of 144.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 717 from 861 to get 144.
Take the next digit (2) from the dividend and append it to 144, then repeat: 1442 / 717

On to step 4:
If we divide 1442 by 717, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1434 away from 1442, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 717

Advancing to step 5:
80 divided by 717 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we subtract 0 from 80, we get 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 717

Advancing to step 6:
807 divided by 717 is 1 with a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 1201.0
Deduct 717 from 807 and we're left with 90.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 717

Let's proceed to step 7:
900 divided by 717 is 1 with a remainder of 183.
Put 1 as the next digit of the answer. 
Result so far: 12011.0
The remainder is 183 after subtracting 717 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 8:
1830 divided by 717 is 2 with a remainder of 396.
The next digit of our result is 2. 
Result so far: 12011.2
Subtract 1434 from 1830 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 9:
The number 717 fits into 3960 5 times, leaving a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 12011.25
If we take 3585 away from 3960, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 10:
717 goes into 3750 5 times with a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 12011.255
Deduct 3585 from 3750 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The quotient of the division is 12011.255, and the remainder is 0.0165.
