We look at the division of 19425952 by 819 
The aim is to understand the frequency of 819 in 19425952.

On to step 1:
819 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 819

On to step 2:
819 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 819

Going ahead to step 3:
819 can be fit into 194 0 times, resulting in a remainder of 194.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 194, we get 194.
Append the next digit (2) from the dividend to 194 and continue with: 1942 / 819

Going ahead to step 4:
If we divide 1942 by 819, we get 2 and a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1638 from 1942, we get 304.
Bring next digit (5) of the dividend behind the 304 and repeat the process: 3045 / 819

Moving on to step 5:
The number 819 fits into 3045 3 times, leaving a remainder of 588.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 588 after subtracting 2457 from 3045.
Grab the next digit (9) from the dividend, add it to 588, then carry on: 5889 / 819

On to step 6:
819 can be fit into 5889 7 times, resulting in a remainder of 156.
Put 7 as the next digit of the answer. 
Result so far: 237.0
If we take 5733 away from 5889, we end up with 156.
Fetch the next digit (5) from the dividend, attach it to 156 and continue: 1565 / 819

Moving on to step 7:
819 can be fit into 1565 1 times, resulting in a remainder of 746.
Write down 1 as next digit of the result. 
Result so far: 2371.0
The remainder is 746 after subtracting 819 from 1565.
Fetch the next digit (2) from the dividend, attach it to 746 and continue: 7462 / 819

Going ahead to step 8:
819 goes into 7462 9 times with a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 23719.0
If we subtract 7371 from 7462, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 9:
If we divide 910 by 819, we get 1 and a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 23719.1
If we take 819 away from 910, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 10:
819 can be fit into 910 1 times, resulting in a remainder of 91.
The next digit of our result is 1. 
Result so far: 23719.11
The remainder is 91 after subtracting 819 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

In conclusion, the division gives 23719.11 with a balance of 0.091.
