Let's divide 122190 by 30
Our goal is to divide 122190 by 30.

On to step 1:
If we divide 1 by 30, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 30

Let's proceed to step 2:
30 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 30

Moving on to step 3:
122 divided by 30 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 120 from 122 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 30

Let's proceed to step 4:
The number 30 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 30

Let's proceed to step 5:
30 goes into 219 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
The remainder is 9 after subtracting 210 from 219.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 30

Let's proceed to step 6:
If we divide 90 by 30, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 4073.0
Subtract 90 from 90 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 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4073.0
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.

Let's proceed to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4073.0
If we subtract 0 from 0, we 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.

After the division, we end up with 4073.0 and a remainder of 0.0.
