We're dividing 571422 by 15 
We want to figure out the number of times 571422 can be divided by 15.

Step 1:
When dividing 5 by 15, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 15

Going ahead to step 2:
15 goes into 57 3 times with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 45 from 57 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 15

Going ahead to step 3:
121 divided by 15 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 120 from 121 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 15

On to step 4:
15 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 380.0
Subtract 0 from 14 to get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 15

Going ahead to step 5:
15 can be fit into 142 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 3809.0
If we subtract 135 from 142, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 15

Going ahead to step 6:
72 divided by 15 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 38094.0
If we take 60 away from 72, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
120 divided by 15 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 38094.8
Subtract 120 from 120 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.

On to step 8:
0 divided by 15 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 38094.8
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.

On to step 9:
15 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 38094.8
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 38094.8, with a leftover of 0.0.
