We look at the division of 302391 by 85 
We're looking to find how many times 85 goes into 302391.

Moving on to step 1:
85 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 85

Advancing to step 2:
85 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 85

On to step 3:
302 divided by 85 is 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 255 from 302 to get 47.
Append the next digit (3) from the dividend to 47 and continue with: 473 / 85

On to step 4:
85 goes into 473 5 times with a remainder of 48.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 425 from 473 and we're left with 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 85

Step 5:
85 can be fit into 489 5 times, resulting in a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 355.0
Deduct 425 from 489 and we're left with 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 85

Moving on to step 6:
641 divided by 85 is 7 with a remainder of 46.
The next digit of our result is 7. 
Result so far: 3557.0
If we take 595 away from 641, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
The number 85 fits into 460 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 3557.5
Subtract 425 from 460 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
350 divided by 85 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 3557.54
If we subtract 340 from 350, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 3557.541
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
When dividing 150 by 85, we get 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 3557.5411
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 3557.5411, and the remainder is 0.00065.
