We divide 356426 by 18
We're looking to find how many times 18 goes into 356426.

On to step 1:
When dividing 3 by 18, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 18

Going ahead to step 2:
If we divide 35 by 18, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 18 from 35 to get 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 18

Going ahead to step 3:
18 goes into 176 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 162 away from 176, we end up with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 18

Step 4:
If we divide 144 by 18, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 198.0
Deduct 144 from 144 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 18

Let's proceed to step 5:
If we divide 2 by 18, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 1980.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 18

Step 6:
18 can be fit into 26 1 times, resulting in a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 19801.0
The remainder is 8 after subtracting 18 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
If we divide 80 by 18, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 19801.4
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
If we divide 80 by 18, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 19801.44
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 19801.44 with a remainder of 0.008.
