We're dividing 422168 by 15 
Our goal is to divide 422168 by 15.

Moving on to step 1:
15 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 15

Advancing to step 2:
The number 15 fits into 42 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 30 from 42 to get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 15

Advancing to step 3:
If we divide 122 by 15, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 2 after subtracting 120 from 122.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 15

Moving on to step 4:
When dividing 21 by 15, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 281.0
Subtract 15 from 21 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 15

Moving on to step 5:
The number 15 fits into 66 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 2814.0
Subtract 60 from 66 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 15

Step 6:
15 goes into 68 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 28144.0
If we take 60 away from 68, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
The number 15 fits into 80 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 28144.5
If we subtract 75 from 80, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
15 goes into 50 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 28144.53
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 28144.533
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 28144.533, with a leftover of 0.0005.
