We divide 420228 by 30
Let's see how many times 30 fits into 420228.

Let's proceed to step 1:
The number 30 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 30

Advancing to step 2:
When dividing 42 by 30, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 30 from 42 and we're left with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 30

Advancing to step 3:
120 divided by 30 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 120 from 120 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 30

Going ahead to step 4:
If we divide 2 by 30, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 30

Step 5:
30 can be fit into 22 0 times, resulting in a remainder of 22.
The next digit of our result is 0. 
Result so far: 1400.0
Subtract 0 from 22 to get 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 30

Advancing to step 6:
30 goes into 228 7 times with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 14007.0
If we take 210 away from 228, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
If we divide 180 by 30, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 14007.6
The remainder is 0 after subtracting 180 from 180.
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:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 14007.6
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.

Going ahead to step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14007.6
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 14007.6 and a remainder of 0.0.
