391939 divided by 85 
We're looking to find how many times 85 goes into 391939.

On to step 1:
85 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 85

On to step 2:
39 divided by 85 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 85

Let's proceed to step 3:
The number 85 fits into 391 4 times, leaving a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 51 after subtracting 340 from 391.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 85

Going ahead to step 4:
519 divided by 85 is 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 510 from 519 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 85

Step 5:
When dividing 93 by 85, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 461.0
If we take 85 away from 93, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 85

Moving on to step 6:
The number 85 fits into 89 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 4611.0
If we take 85 away from 89, we end up 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.

Advancing to step 7:
40 divided by 85 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4611.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
If we divide 400 by 85, we get 4 and a remainder of 60.
The next digit of our result is 4. 
Result so far: 4611.04
Deduct 340 from 400 and we're left 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.

Step 9:
85 can be fit into 600 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 4611.047
Subtract 595 from 600 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
85 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 4611.047
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 4611.04705
If we subtract 425 from 500, we get 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 12:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 4611.047058
The remainder is 70 after subtracting 680 from 750.
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 13:
85 goes into 700 8 times with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 4611.0470588
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.

The final outcome is 4611.0470588, with a leftover of 2e-07.
