We look at the division of 21141822 by 302 
The aim is to understand the frequency of 302 in 21141822.

Moving on to step 1:
302 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 302

Going ahead to step 2:
21 divided by 302 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 302

On to step 3:
211 divided by 302 is 0 with a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 211 to get 211.
Grab the next digit (4) from the dividend, add it to 211, then carry on: 2114 / 302

Moving on to step 4:
The number 302 fits into 2114 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
If we take 2114 away from 2114, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 302

Advancing to step 5:
When dividing 1 by 302, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 302

Advancing to step 6:
302 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 700.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 302

Moving on to step 7:
302 can be fit into 182 0 times, resulting in a remainder of 182.
Write down 0 as next digit of the result. 
Result so far: 7000.0
Deduct 0 from 182 and we're left with 182.
Bring next digit (2) of the dividend behind the 182 and repeat the process: 1822 / 302

Moving on to step 8:
If we divide 1822 by 302, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 70006.0
If we subtract 1812 from 1822, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
302 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 70006.0
Subtracting 0 from 100 leaves us 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.

Advancing to step 10:
The number 302 fits into 1000 3 times, leaving a remainder of 94.
The number 3 becomes the next digit in our result. 
Result so far: 70006.03
Subtracting 906 from 1000 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 11:
The number 302 fits into 940 3 times, leaving a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 70006.033
Deduct 906 from 940 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 70006.033 with a remainder of 0.0034.
