83539 ÷ 15 
Let's see how many times 15 fits into 83539.

Step 1:
If we divide 8 by 15, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 15

Moving on to step 2:
When dividing 83 by 15, we get 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 75 from 83 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 15

Let's proceed to step 3:
If we divide 85 by 15, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we subtract 75 from 85, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 15

Going ahead to step 4:
When dividing 103 by 15, we get 6 with a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 556.0
If we take 90 away from 103, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 15

Moving on to step 5:
15 can be fit into 139 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 5569.0
Subtracting 135 from 139 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.

Let's proceed to step 6:
40 divided by 15 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 5569.2
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 5569.26
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.

Going ahead to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 5569.266
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.

After the division, we end up with 5569.266 and a remainder of 0.001.
