We look at the division of 21965925 by 442 
The aim is to understand the frequency of 442 in 21965925.

Moving on to step 1:
When dividing 2 by 442, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 442

Moving on to step 2:
442 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 442

Let's proceed to step 3:
When dividing 219 by 442, we get 0 with a remainder of 219.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 219, we get 219.
Grab the next digit (6) from the dividend, add it to 219, then carry on: 2196 / 442

Step 4:
The number 442 fits into 2196 4 times, leaving a remainder of 428.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 428 after subtracting 1768 from 2196.
Take the next digit (5) from the dividend and append it to 428, then repeat: 4285 / 442

Advancing to step 5:
When dividing 4285 by 442, we get 9 with a remainder of 307.
The next digit of our result is 9. 
Result so far: 49.0
Subtracting 3978 from 4285 leaves us with 307.
Fetch the next digit (9) from the dividend, attach it to 307 and continue: 3079 / 442

On to step 6:
442 goes into 3079 6 times with a remainder of 427.
Write down 6 as next digit of the result. 
Result so far: 496.0
If we subtract 2652 from 3079, we get 427.
Include the next digit (2) from the dividend after 427, then repeat: 4272 / 442

On to step 7:
When dividing 4272 by 442, we get 9 with a remainder of 294.
Use 9 as the next digit of our solution. 
Result so far: 4969.0
Subtracting 3978 from 4272 leaves us with 294.
Include the next digit (5) from the dividend after 294, then repeat: 2945 / 442

On to step 8:
442 goes into 2945 6 times with a remainder of 293.
The next digit of our result is 6. 
Result so far: 49696.0
The remainder is 293 after subtracting 2652 from 2945.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 9:
442 can be fit into 2930 6 times, resulting in a remainder of 278.
Use 6 as the next digit of our solution. 
Result so far: 49696.6
Subtracting 2652 from 2930 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 10:
If we divide 2780 by 442, we get 6 and a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 49696.66
Deduct 2652 from 2780 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 49696.66, and the remainder is 0.128.
