392553 ÷ 85 
We want to figure out the number of times 392553 can be divided by 85.

Let's proceed to step 1:
When dividing 3 by 85, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 85

Advancing to step 2:
If we divide 39 by 85, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 85

On to step 3:
392 divided by 85 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 340 from 392 and we're left with 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 85

Advancing to step 4:
The number 85 fits into 525 6 times, leaving a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Deduct 510 from 525 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 85

Going ahead to step 5:
The number 85 fits into 155 1 times, leaving a remainder of 70.
The next digit of our result is 1. 
Result so far: 461.0
If we subtract 85 from 155, we get 70.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 85

Advancing to step 6:
703 divided by 85 is 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 4618.0
If we take 680 away from 703, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
230 divided by 85 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 4618.2
Subtracting 170 from 230 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
600 divided by 85 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 4618.27
If we take 595 away from 600, we end up 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.

Step 9:
The number 85 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 4618.27
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
When dividing 500 by 85, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 4618.2705
Deduct 425 from 500 and we're left 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.

On to step 11:
When dividing 750 by 85, we get 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 4618.27058
If we subtract 680 from 750, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
When dividing 700 by 85, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 4618.270588
Subtract 680 from 700 to 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.

Our division results in 4618.270588 with a remaining 2e-06.
