Let's divide 631519 by 18
Let's see how many times 18 fits into 631519.

Going ahead to step 1:
18 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 18

Let's proceed to step 2:
If we divide 63 by 18, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 54 away from 63, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 18

Going ahead to step 3:
If we divide 91 by 18, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we subtract 90 from 91, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 18

Advancing to step 4:
When dividing 15 by 18, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 350.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 18

On to step 5:
The number 18 fits into 151 8 times, leaving a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 3508.0
The remainder is 7 after subtracting 144 from 151.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 18

Advancing to step 6:
79 divided by 18 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 35084.0
Subtracting 72 from 79 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 18, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 35084.3
If we take 54 away from 70, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
160 divided by 18 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 35084.38
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
When dividing 160 by 18, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 35084.388
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 35084.388 with a balance of 0.0016.
