We divide 122404 by 20
We want to figure out the number of times 122404 can be divided by 20.

On to step 1:
If we divide 1 by 20, 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 take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 20

Advancing to step 2:
20 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 20

Let's proceed to step 3:
20 goes into 122 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 120 from 122 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 20

Let's proceed to step 4:
20 can be fit into 24 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Deduct 20 from 24 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 20

Moving on to step 5:
20 goes into 40 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 612.0
The remainder is 0 after subtracting 40 from 40.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 20

Moving on to step 6:
When dividing 4 by 20, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 6120.0
Subtracting 0 from 4 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
20 can be fit into 40 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 6120.2
If we take 40 away from 40, 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 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 6120.2
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.

Let's proceed to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 6120.2
The remainder is 0 after subtracting 0 from 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 final outcome is 6120.2, with a leftover of 0.0.
