We divide 175321 by 15
We're looking to find how many times 15 goes into 175321.

Moving on to step 1:
15 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 15

Advancing to step 2:
The number 15 fits into 17 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 15 from 17, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 15

Going ahead to step 3:
If we divide 25 by 15, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 15 from 25 leaves us with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 15

Step 4:
15 goes into 103 6 times with a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 116.0
If we subtract 90 from 103, we get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 15

Step 5:
When dividing 132 by 15, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 1168.0
If we subtract 120 from 132, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 15

Moving on to step 6:
When dividing 121 by 15, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 11688.0
Subtracting 120 from 121 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
If we divide 10 by 15, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 11688.0
The remainder is 10 after subtracting 0 from 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:
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: 11688.06
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.

Advancing to step 9:
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: 11688.066
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.

The final outcome is 11688.066, with a leftover of 0.001.
