We look at the division of 431742 by 15 
We want to divide 431742 by 15.

Moving on to step 1:
15 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 15

Let's proceed to step 2:
The number 15 fits into 43 2 times, leaving a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 13 after subtracting 30 from 43.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 15

Let's proceed to step 3:
If we divide 131 by 15, we get 8 and a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 120 away from 131, we end up with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 15

Moving on to step 4:
If we divide 117 by 15, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 287.0
Subtract 105 from 117 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 15

Moving on to step 5:
The number 15 fits into 124 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 2878.0
Subtract 120 from 124 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 15

Moving on to step 6:
When dividing 42 by 15, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 28782.0
Deduct 30 from 42 and we're left 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.

Going ahead to step 7:
The number 15 fits into 120 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 28782.8
Subtracting 120 from 120 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.

Advancing to step 8:
15 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28782.8
Deduct 0 from 0 and we're left 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.

Going ahead to step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28782.8
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.

The quotient of the division is 28782.8, and the remainder is 0.0.
