Let's divide 18371 by 15
Our goal is to divide 18371 by 15.

Let's proceed to step 1:
1 divided by 15 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 15

On to step 2:
When dividing 18 by 15, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 15 from 18, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 15

Let's proceed to step 3:
The number 15 fits into 33 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 3 after subtracting 30 from 33.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 15

On to step 4:
15 can be fit into 37 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 122.0
The remainder is 7 after subtracting 30 from 37.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 15

Let's proceed to step 5:
15 goes into 71 4 times with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 1224.0
The remainder is 11 after subtracting 60 from 71.
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:
15 can be fit into 110 7 times, resulting in a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 1224.7
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:
15 goes into 50 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 1224.73
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
15 goes into 50 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 1224.733
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 1224.733, with a leftover of 0.0005.
