We divide 8749 by 15
Our goal is to divide 8749 by 15.

Going ahead to step 1:
15 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 15

Advancing to step 2:
The number 15 fits into 87 5 times, leaving a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 75 from 87, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 15

Going ahead to step 3:
15 goes into 124 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
If we subtract 120 from 124, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 15

Going ahead to step 4:
15 goes into 49 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 583.0
Deduct 45 from 49 and we're left 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.

Moving on to step 5:
15 can be fit into 40 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 583.2
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.

On to step 6:
If we divide 100 by 15, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 583.26
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.

Step 7:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 583.266
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.

The final outcome is 583.266, with a leftover of 0.001.
