Let's divide 817123 by 85
Our goal is to divide 817123 by 85.

Advancing to step 1:
85 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 85

Moving on to step 2:
The number 85 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 85

Moving on to step 3:
If we divide 817 by 85, we get 9 and a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 765 from 817, we get 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 85

Advancing to step 4:
The number 85 fits into 521 6 times, leaving a remainder of 11.
The next digit of our result is 6. 
Result so far: 96.0
If we subtract 510 from 521, we get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 85

On to step 5:
85 can be fit into 112 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 961.0
The remainder is 27 after subtracting 85 from 112.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 85

Moving on to step 6:
If we divide 273 by 85, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 9613.0
Subtract 255 from 273 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 85 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 9613.2
If we take 170 away from 180, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 85 fits into 100 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 9613.21
Deduct 85 from 100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 9613.211
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 9613.211 and a remainder of 0.0065.
