We're dividing 333518 by 86 
Our goal is to divide 333518 by 86.

On to step 1:
The number 86 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 86

Going ahead to step 2:
If we divide 33 by 86, we get 0 and a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 86

Let's proceed to step 3:
86 can be fit into 333 3 times, resulting in a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 258 from 333 to get 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 86

On to step 4:
86 can be fit into 755 8 times, resulting in a remainder of 67.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 688 from 755 to get 67.
Grab the next digit (1) from the dividend, add it to 67, then carry on: 671 / 86

Going ahead to step 5:
When dividing 671 by 86, we get 7 with a remainder of 69.
The next digit of our result is 7. 
Result so far: 387.0
If we subtract 602 from 671, we get 69.
Fetch the next digit (8) from the dividend, attach it to 69 and continue: 698 / 86

Advancing to step 6:
698 divided by 86 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 3878.0
The remainder is 10 after subtracting 688 from 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
86 goes into 100 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 3878.1
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
If we divide 140 by 86, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 3878.11
Subtract 86 from 140 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 3878.11 and a remainder of 0.054.
