We look at the division of 122224 by 42 
We're looking to find how many times 42 goes into 122224.

Let's proceed to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 42

Step 2:
42 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 42

On to step 3:
122 divided by 42 is 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 84 away from 122, we end up with 38.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 42

Let's proceed to step 4:
If we divide 382 by 42, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
The remainder is 4 after subtracting 378 from 382.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 42

Advancing to step 5:
42 goes into 42 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 291.0
Deduct 42 from 42 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 42

Step 6:
42 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 2910.0
Subtract 0 from 4 to get 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:
42 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 2910.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
When dividing 400 by 42, we get 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 2910.09
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
220 divided by 42 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 2910.095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
42 goes into 100 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2910.0952
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
If we divide 160 by 42, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 2910.09523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 2910.095238
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
40 divided by 42 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2910.095238
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
42 goes into 400 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 2910.09523809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 2910.09523809 and a remainder of 2.2e-08.
