363959 divided by 85 
Our goal is to divide 363959 by 85.

Step 1:
When dividing 3 by 85, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 85

Step 2:
When dividing 36 by 85, we get 0 with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 85

On to step 3:
The number 85 fits into 363 4 times, leaving a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 340 from 363 leaves us with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 85

On to step 4:
When dividing 239 by 85, we get 2 with a remainder of 69.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 69 after subtracting 170 from 239.
Include the next digit (5) from the dividend after 69, then repeat: 695 / 85

Going ahead to step 5:
695 divided by 85 is 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 428.0
If we take 680 away from 695, we end up with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 85

Let's proceed to step 6:
85 can be fit into 159 1 times, resulting in a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 4281.0
Subtracting 85 from 159 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 7:
85 goes into 740 8 times with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 4281.8
If we take 680 away from 740, we end up 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.

On to step 8:
85 can be fit into 600 7 times, resulting in a remainder of 5.
The next digit of our result is 7. 
Result so far: 4281.87
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.

Advancing to step 9:
The number 85 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4281.87
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.

Going ahead to step 10:
85 goes into 500 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 4281.8705
Subtracting 425 from 500 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.

Step 11:
When dividing 750 by 85, we get 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 4281.87058
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.

Step 12:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 4281.870588
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.

In conclusion, the division gives 4281.870588 with a balance of 2e-06.
