Let's divide 19442377 by 819
The aim is to understand the frequency of 819 in 19442377.

On to step 1:
If we divide 1 by 819, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 819

Moving on to step 2:
When dividing 19 by 819, we get 0 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.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 819

Going ahead to step 3:
819 goes into 194 0 times with a remainder of 194.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 194 leaves us with 194.
Take the next digit (4) from the dividend and append it to 194, then repeat: 1944 / 819

On to step 4:
819 can be fit into 1944 2 times, resulting in a remainder of 306.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 306 after subtracting 1638 from 1944.
Append the next digit (2) from the dividend to 306 and continue with: 3062 / 819

Advancing to step 5:
When dividing 3062 by 819, we get 3 with a remainder of 605.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 605 after subtracting 2457 from 3062.
Grab the next digit (3) from the dividend, add it to 605, then carry on: 6053 / 819

On to step 6:
6053 divided by 819 is 7 with a remainder of 320.
The next digit of our result is 7. 
Result so far: 237.0
If we subtract 5733 from 6053, we get 320.
Fetch the next digit (7) from the dividend, attach it to 320 and continue: 3207 / 819

Going ahead to step 7:
819 goes into 3207 3 times with a remainder of 750.
Use 3 as the next digit of our solution. 
Result so far: 2373.0
If we take 2457 away from 3207, we end up with 750.
Fetch the next digit (7) from the dividend, attach it to 750 and continue: 7507 / 819

On to step 8:
If we divide 7507 by 819, we get 9 and a remainder of 136.
Put 9 as the next digit of the answer. 
Result so far: 23739.0
If we subtract 7371 from 7507, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 9:
819 goes into 1360 1 times with a remainder of 541.
The next digit of our result is 1. 
Result so far: 23739.1
The remainder is 541 after subtracting 819 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

On to step 10:
The number 819 fits into 5410 6 times, leaving a remainder of 496.
Record the quotient 6 as the next digit in the result. 
Result so far: 23739.16
Subtracting 4914 from 5410 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 11:
819 goes into 4960 6 times with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 23739.166
Subtract 4914 from 4960 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 23739.166 with a remaining 0.0046.
