We divide 602152 by 15
We want to figure out the number of times 602152 can be divided by 15.

Step 1:
6 divided by 15 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 15

Let's proceed to step 2:
The number 15 fits into 60 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 0 after subtracting 60 from 60.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 15

On to step 3:
15 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 15

Let's proceed to step 4:
21 divided by 15 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 401.0
Deduct 15 from 21 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 15

Step 5:
15 goes into 65 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4014.0
Subtracting 60 from 65 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 15

Step 6:
15 can be fit into 52 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 40143.0
Subtracting 45 from 52 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
15 goes into 70 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 40143.4
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 40143.46
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 40143.466
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 40143.466 with a remaining 0.001.
