422235 ÷ 15 
Let's see how many times 15 fits into 422235.

Moving on to step 1:
When dividing 4 by 15, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 15

On to step 2:
42 divided by 15 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 30 from 42 and we're left with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 15

On to step 3:
15 can be fit into 122 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 120 from 122 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 15

Step 4:
The number 15 fits into 22 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 281.0
The remainder is 7 after subtracting 15 from 22.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 15

Advancing to step 5:
The number 15 fits into 73 4 times, leaving a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 2814.0
Deduct 60 from 73 and we're left with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 15

Advancing to step 6:
The number 15 fits into 135 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 28149.0
If we take 135 away from 135, 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 7:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28149.0
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.

Moving on to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28149.0
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 28149.0 and a remainder of 0.0.
