We're dividing 315829 by 18 
We want to figure out the number of times 315829 can be divided by 18.

Advancing to step 1:
The number 18 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 18

Going ahead to step 2:
When dividing 31 by 18, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 18 away from 31, we end up with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 18

Moving on to step 3:
If we divide 135 by 18, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 126 away from 135, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 18

Moving on to step 4:
The number 18 fits into 98 5 times, leaving a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
Deduct 90 from 98 and we're left with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 18

Advancing to step 5:
If we divide 82 by 18, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 1754.0
Subtracting 72 from 82 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 18

Advancing to step 6:
When dividing 109 by 18, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 17546.0
The remainder is 1 after subtracting 108 from 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
18 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 17546.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
18 goes into 100 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 17546.05
If we subtract 90 from 100, 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.

Going ahead to step 9:
18 goes into 100 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 17546.055
Subtract 90 from 100 to 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.

The final result is 17546.055 with a remainder of 0.001.
