Let's divide 420474 by 18
We want to figure out the number of times 420474 can be divided by 18.

Advancing to step 1:
4 divided by 18 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 18

On to step 2:
42 divided by 18 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 36 from 42 to get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 18

Going ahead to step 3:
If we divide 60 by 18, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 6 after subtracting 54 from 60.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 18

On to step 4:
18 can be fit into 64 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
If we subtract 54 from 64, we get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 18

Going ahead to step 5:
When dividing 107 by 18, we get 5 with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 2335.0
If we subtract 90 from 107, we get 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 18

Moving on to step 6:
18 goes into 174 9 times with a remainder of 12.
The next digit of our result is 9. 
Result so far: 23359.0
If we take 162 away from 174, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
18 can be fit into 120 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 23359.6
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 23359.66
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 23359.66, and the remainder is 0.012.
