15372 divided by 42 
Let's see how many times 42 fits into 15372.

On to step 1:
42 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 42

Moving on to step 2:
42 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 42

Going ahead to step 3:
If we divide 153 by 42, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 126 from 153 to get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 42

Let's proceed to step 4:
If we divide 277 by 42, we get 6 and a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtracting 252 from 277 leaves us with 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 42

Step 5:
252 divided by 42 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 366.0
Subtract 252 from 252 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.

Going ahead to step 6:
If we divide 0 by 42, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 366.0
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.

Going ahead to step 7:
When dividing 0 by 42, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 366.0
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.

Our division results in 366.0 with a remaining 0.0.
