We look at the division of 44573621 by 422 
The aim is to understand the frequency of 422 in 44573621.

Moving on to step 1:
422 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 422

Moving on to step 2:
44 divided by 422 is 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 422

Advancing to step 3:
If we divide 445 by 422, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 422 from 445 leaves us with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 422

Going ahead to step 4:
If we divide 237 by 422, we get 0 and a remainder of 237.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 237 leaves us with 237.
Bring next digit (3) of the dividend behind the 237 and repeat the process: 2373 / 422

On to step 5:
If we divide 2373 by 422, we get 5 and a remainder of 263.
Put 5 as the next digit of the answer. 
Result so far: 105.0
If we take 2110 away from 2373, we end up with 263.
Take the next digit (6) from the dividend and append it to 263, then repeat: 2636 / 422

Advancing to step 6:
422 can be fit into 2636 6 times, resulting in a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 1056.0
Deduct 2532 from 2636 and we're left with 104.
Grab the next digit (2) from the dividend, add it to 104, then carry on: 1042 / 422

Let's proceed to step 7:
422 can be fit into 1042 2 times, resulting in a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 10562.0
If we subtract 844 from 1042, we get 198.
Fetch the next digit (1) from the dividend, attach it to 198 and continue: 1981 / 422

Going ahead to step 8:
422 goes into 1981 4 times with a remainder of 293.
Record the quotient 4 as the next digit in the result. 
Result so far: 105624.0
Subtracting 1688 from 1981 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Let's proceed to step 9:
422 goes into 2930 6 times with a remainder of 398.
The next digit of our result is 6. 
Result so far: 105624.6
Subtracting 2532 from 2930 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 10:
The number 422 fits into 3980 9 times, leaving a remainder of 182.
Record the quotient 9 as the next digit in the result. 
Result so far: 105624.69
Subtract 3798 from 3980 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 11:
1820 divided by 422 is 4 with a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 105624.694
The remainder is 132 after subtracting 1688 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 12:
422 can be fit into 1320 3 times, resulting in a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 105624.6943
If we subtract 1266 from 1320, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 13:
540 divided by 422 is 1 with a remainder of 118.
The number 1 becomes the next digit in our result. 
Result so far: 105624.69431
Subtracting 422 from 540 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 14:
If we divide 1180 by 422, we get 2 and a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 105624.694312
If we subtract 844 from 1180, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 15:
The number 422 fits into 3360 7 times, leaving a remainder of 406.
The next digit of our result is 7. 
Result so far: 105624.6943127
If we subtract 2954 from 3360, we get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 16:
If we divide 4060 by 422, we get 9 and a remainder of 262.
The next digit of our result is 9. 
Result so far: 105624.69431279
Subtract 3798 from 4060 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Our division results in 105624.69431279 with a remaining 2.62e-07.
