We divide 15219 by 81
Let's see how many times 81 fits into 15219.

On to step 1:
81 goes into 1 0 times 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 (5) from the dividend to 1 and continue with: 15 / 81

Step 2:
81 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 81

On to step 3:
When dividing 152 by 81, we get 1 with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 81 away from 152, we end up with 71.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 81

Going ahead to step 4:
81 goes into 711 8 times with a remainder of 63.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 648 from 711, we get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 81

Let's proceed to step 5:
If we divide 639 by 81, we get 7 and a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 187.0
If we subtract 567 from 639, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 6:
720 divided by 81 is 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 187.8
The remainder is 72 after subtracting 648 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
The number 81 fits into 720 8 times, leaving a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 187.88
The remainder is 72 after subtracting 648 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 187.88, and the remainder is 0.072.
