Let's divide 22998431 by 400
The aim is to understand the frequency of 400 in 22998431.

Moving on to step 1:
2 divided by 400 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 400

Moving on to step 2:
400 goes into 22 0 times with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 400

On to step 3:
When dividing 229 by 400, we get 0 with a remainder of 229.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 229 after subtracting 0 from 229.
Take the next digit (9) from the dividend and append it to 229, then repeat: 2299 / 400

Moving on to step 4:
If we divide 2299 by 400, we get 5 and a remainder of 299.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 2000 from 2299, we get 299.
Fetch the next digit (8) from the dividend, attach it to 299 and continue: 2998 / 400

Advancing to step 5:
400 goes into 2998 7 times with a remainder of 198.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtracting 2800 from 2998 leaves us with 198.
Take the next digit (4) from the dividend and append it to 198, then repeat: 1984 / 400

Advancing to step 6:
The number 400 fits into 1984 4 times, leaving a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 574.0
If we subtract 1600 from 1984, we get 384.
Fetch the next digit (3) from the dividend, attach it to 384 and continue: 3843 / 400

Advancing to step 7:
If we divide 3843 by 400, we get 9 and a remainder of 243.
The number 9 becomes the next digit in our result. 
Result so far: 5749.0
Deduct 3600 from 3843 and we're left with 243.
Include the next digit (1) from the dividend after 243, then repeat: 2431 / 400

Advancing to step 8:
When dividing 2431 by 400, we get 6 with a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 57496.0
The remainder is 31 after subtracting 2400 from 2431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
400 can be fit into 310 0 times, resulting in a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 57496.0
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 10:
If we divide 3100 by 400, we get 7 and a remainder of 300.
The next digit of our result is 7. 
Result so far: 57496.07
If we subtract 2800 from 3100, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
400 can be fit into 3000 7 times, resulting in a remainder of 200.
Use 7 as the next digit of our solution. 
Result so far: 57496.077
Subtracting 2800 from 3000 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 57496.077 with a remainder of 0.02.
