We look at the division of 425520 by 30 
We want to divide 425520 by 30.

Advancing to step 1:
If we divide 4 by 30, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 30

Going ahead to step 2:
42 divided by 30 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we take 30 away from 42, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 30

On to step 3:
If we divide 125 by 30, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 120 from 125 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 30

Going ahead to step 4:
The number 30 fits into 55 1 times, leaving a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
If we take 30 away from 55, we end up with 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 30

Advancing to step 5:
The number 30 fits into 252 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1418.0
If we take 240 away from 252, we end up with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 30

Moving on to step 6:
30 goes into 120 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 14184.0
Subtract 120 from 120 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
30 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14184.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14184.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 14184.0, and the remainder is 0.0.
