Let's divide 181253 by 15
We want to divide 181253 by 15.

Let's proceed to step 1:
If we divide 1 by 15, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 15

Going ahead to step 2:
When dividing 18 by 15, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 15 from 18 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 15

On to step 3:
15 can be fit into 31 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 30 from 31 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 15

Step 4:
15 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 15

On to step 5:
The number 15 fits into 125 8 times, leaving a remainder of 5.
The next digit of our result is 8. 
Result so far: 1208.0
Subtracting 120 from 125 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 15

On to step 6:
If we divide 53 by 15, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 12083.0
Subtracting 45 from 53 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
When dividing 80 by 15, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 12083.5
The remainder is 5 after subtracting 75 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 12083.53
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.

On to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 12083.533
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.

Our division results in 12083.533 with a remaining 0.0005.
