We look at the division of 330899 by 86 
We want to divide 330899 by 86.

Let's proceed to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 86

Going ahead to step 2:
When dividing 33 by 86, we get 0 with a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 86

Advancing to step 3:
When dividing 330 by 86, we get 3 with a remainder of 72.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 72 after subtracting 258 from 330.
Append the next digit (8) from the dividend to 72 and continue with: 728 / 86

Step 4:
86 goes into 728 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we take 688 away from 728, we end up with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 86

Step 5:
409 divided by 86 is 4 with a remainder of 65.
Record the quotient 4 as the next digit in the result. 
Result so far: 384.0
The remainder is 65 after subtracting 344 from 409.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 86

Advancing to step 6:
86 can be fit into 659 7 times, resulting in a remainder of 57.
The next digit of our result is 7. 
Result so far: 3847.0
The remainder is 57 after subtracting 602 from 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
The number 86 fits into 570 6 times, leaving a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 3847.6
If we take 516 away from 570, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
86 goes into 540 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 3847.66
Deduct 516 from 540 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 3847.66 with a remaining 0.024.
