We divide 391311 by 85
We want to divide 391311 by 85.

Let's proceed to step 1:
85 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
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

Let's proceed to step 2:
85 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 85

Moving on to step 3:
If we divide 391 by 85, we get 4 and a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 340 from 391 leaves us with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 85

On to step 4:
85 can be fit into 513 6 times, resulting in a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtracting 510 from 513 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 85

Advancing to step 5:
85 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 460.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 85

On to step 6:
85 can be fit into 311 3 times, resulting in a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 4603.0
Subtract 255 from 311 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 7:
When dividing 560 by 85, we get 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 4603.6
The remainder is 50 after subtracting 510 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
The number 85 fits into 500 5 times, leaving a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 4603.65
Subtract 425 from 500 to 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.

Let's proceed to step 9:
The number 85 fits into 750 8 times, leaving a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 4603.658
If we take 680 away from 750, we end up 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.

Advancing to step 10:
85 goes into 700 8 times with a remainder of 20.
The next digit of our result is 8. 
Result so far: 4603.6588
Subtracting 680 from 700 leaves us with 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 4603.6588 with a remainder of 0.0002.
