We divide 631433 by 18
Let's see how many times 18 fits into 631433.

Going ahead to step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 18

Moving on to step 2:
18 goes into 63 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 54 from 63 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 18

Moving on to step 3:
If we divide 91 by 18, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 90 from 91 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 18

Advancing to step 4:
If we divide 14 by 18, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 350.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 18

Step 5:
143 divided by 18 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 3507.0
Deduct 126 from 143 and we're left with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 18

Let's proceed to step 6:
If we divide 173 by 18, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 35079.0
Subtracting 162 from 173 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 18, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 35079.6
Subtract 108 from 110 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 18 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 35079.61
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
If we divide 20 by 18, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 35079.611
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 35079.611 with a remainder of 0.0002.
