We look at the division of 21803530 by 190 
The aim is to understand the frequency of 190 in 21803530.

On to step 1:
When dividing 2 by 190, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 190

Step 2:
21 divided by 190 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 190

Moving on to step 3:
If we divide 218 by 190, we get 1 and a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 190 from 218, we get 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 190

On to step 4:
190 goes into 280 1 times with a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 190 from 280 and we're left with 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 190

Advancing to step 5:
The number 190 fits into 903 4 times, leaving a remainder of 143.
Write down 4 as next digit of the result. 
Result so far: 114.0
If we subtract 760 from 903, we get 143.
Grab the next digit (5) from the dividend, add it to 143, then carry on: 1435 / 190

Let's proceed to step 6:
The number 190 fits into 1435 7 times, leaving a remainder of 105.
The number 7 becomes the next digit in our result. 
Result so far: 1147.0
Deduct 1330 from 1435 and we're left with 105.
Include the next digit (3) from the dividend after 105, then repeat: 1053 / 190

Moving on to step 7:
If we divide 1053 by 190, we get 5 and a remainder of 103.
Put 5 as the next digit of the answer. 
Result so far: 11475.0
Deduct 950 from 1053 and we're left with 103.
Fetch the next digit (0) from the dividend, attach it to 103 and continue: 1030 / 190

Advancing to step 8:
If we divide 1030 by 190, we get 5 and a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 114755.0
Subtract 950 from 1030 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
If we divide 800 by 190, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 114755.4
Deduct 760 from 800 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
The number 190 fits into 400 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 114755.42
If we take 380 away from 400, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
190 goes into 200 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 114755.421
Subtracting 190 from 200 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
When dividing 100 by 190, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 114755.421
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 13:
190 can be fit into 1000 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 114755.42105
Subtracting 950 from 1000 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
190 can be fit into 500 2 times, resulting in a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 114755.421052
If we take 380 away from 500, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
1200 divided by 190 is 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 114755.4210526
Deduct 1140 from 1200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 16:
600 divided by 190 is 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 114755.42105263
If we take 570 away from 600, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 114755.42105263 with a remaining 3e-08.
