We're dividing 912423 by 85 
We want to figure out the number of times 912423 can be divided by 85.

Going ahead to step 1:
9 divided by 85 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 85

Step 2:
When dividing 91 by 85, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 85 from 91, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 85

Going ahead to step 3:
62 divided by 85 is 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 62, we get 62.
Grab the next digit (4) from the dividend, add it to 62, then carry on: 624 / 85

Advancing to step 4:
624 divided by 85 is 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 107.0
If we take 595 away from 624, we end up with 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 85

Advancing to step 5:
85 can be fit into 292 3 times, resulting in a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 1073.0
If we subtract 255 from 292, we get 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 85

Let's proceed to step 6:
85 can be fit into 373 4 times, resulting in a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 10734.0
If we take 340 away from 373, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
330 divided by 85 is 3 with a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 10734.3
Subtracting 255 from 330 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 8:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 10734.38
Deduct 680 from 750 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 10734.388
If we subtract 680 from 700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 10734.388 with a remainder of 0.002.
