We're dividing 90052453 by 15 
Let's see how many times 15 fits into 90052453.

Going ahead to step 1:
15 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 15

Let's proceed to step 2:
When dividing 90 by 15, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 90 from 90, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 15

Moving on to step 3:
0 divided by 15 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 15

Let's proceed to step 4:
15 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 600.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 15

Let's proceed to step 5:
When dividing 52 by 15, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 6003.0
Subtracting 45 from 52 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 15

Going ahead to step 6:
15 can be fit into 74 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 60034.0
Subtract 60 from 74 to get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 15

Let's proceed to step 7:
If we divide 145 by 15, we get 9 and a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 600349.0
Subtracting 135 from 145 leaves us with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 15

Moving on to step 8:
15 can be fit into 103 6 times, resulting in a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 6003496.0
If we take 90 away from 103, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
15 can be fit into 130 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 6003496.8
If we take 120 away from 130, 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.

On to step 10:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 6003496.86
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.

Let's proceed to step 11:
100 divided by 15 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 6003496.866
If we subtract 90 from 100, 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.

After the division, we end up with 6003496.866 and a remainder of 0.001.
