We divide 81339 by 19
The aim is to understand the frequency of 19 in 81339.

On to step 1:
When dividing 8 by 19, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 19

Going ahead to step 2:
19 goes into 81 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 76 from 81, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 19

Going ahead to step 3:
If we divide 53 by 19, we get 2 and a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 38 away from 53, we end up with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 19

Moving on to step 4:
153 divided by 19 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 428.0
Subtract 152 from 153 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 19

Advancing to step 5:
When dividing 19 by 19, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 4281.0
Subtract 19 from 19 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 6:
The number 19 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4281.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
0 divided by 19 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4281.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 4281.0 with a remainder of 0.0.
