We look at the division of 661789 by 8 
Our goal is to divide 661789 by 8.

Moving on to step 1:
When dividing 6 by 8, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 8

Moving on to step 2:
8 goes into 66 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 64 from 66 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 8

Moving on to step 3:
If we divide 21 by 8, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we take 16 away from 21, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 8

Going ahead to step 4:
When dividing 57 by 8, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 827.0
The remainder is 1 after subtracting 56 from 57.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 8

Moving on to step 5:
8 goes into 18 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 8272.0
If we subtract 16 from 18, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 8

On to step 6:
29 divided by 8 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 82723.0
Deduct 24 from 29 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
50 divided by 8 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 82723.6
Subtracting 48 from 50 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 8, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 82723.62
Subtracting 16 from 20 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 8 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 82723.625
Deduct 40 from 40 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
8 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 82723.625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 82723.625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 82723.625 and a remainder of 0.0.
