60004159 ÷ 15 
We're looking to find how many times 15 goes into 60004159.

Going ahead to step 1:
15 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 15

Let's proceed to step 2:
When dividing 60 by 15, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 60 from 60 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 15

Moving on to step 3:
When dividing 0 by 15, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 0 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 15

Moving on to step 4:
0 divided by 15 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 400.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 15

On to step 5:
4 divided by 15 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 4000.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 15

Step 6:
41 divided by 15 is 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 40002.0
The remainder is 11 after subtracting 30 from 41.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 15

Moving on to step 7:
If we divide 115 by 15, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 400027.0
The remainder is 10 after subtracting 105 from 115.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 15

On to step 8:
When dividing 109 by 15, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 4000277.0
Subtracting 105 from 109 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
15 can be fit into 40 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 4000277.2
Deduct 30 from 40 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.

On to step 10:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 4000277.26
If we take 90 away from 100, we end up 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.

Moving on to step 11:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 4000277.266
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 4000277.266 with a remainder of 0.001.
