85751 ÷ 15 
Let's see how many times 15 fits into 85751.

Going ahead to step 1:
15 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 15

Advancing to step 2:
When dividing 85 by 15, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 75 away from 85, we end up with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 15

On to step 3:
15 can be fit into 107 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Subtract 105 from 107 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 15

Advancing to step 4:
15 goes into 25 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 571.0
If we subtract 15 from 25, we get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 15

Advancing to step 5:
15 can be fit into 101 6 times, resulting in a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 5716.0
Deduct 90 from 101 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 6:
When dividing 110 by 15, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 5716.7
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 5716.73
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 5716.733
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 5716.733 with a remaining 0.0005.
