We look at the division of 12022512 by 424 
The aim is to understand the frequency of 424 in 12022512.

Moving on to step 1:
424 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 424

Advancing to step 2:
The number 424 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 424

Step 3:
424 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 120, we end up with 120.
Bring next digit (2) of the dividend behind the 120 and repeat the process: 1202 / 424

Moving on to step 4:
When dividing 1202 by 424, we get 2 with a remainder of 354.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 848 from 1202 leaves us with 354.
Take the next digit (2) from the dividend and append it to 354, then repeat: 3542 / 424

Moving on to step 5:
424 goes into 3542 8 times with a remainder of 150.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtracting 3392 from 3542 leaves us with 150.
Append the next digit (5) from the dividend to 150 and continue with: 1505 / 424

On to step 6:
If we divide 1505 by 424, we get 3 and a remainder of 233.
The next digit of our result is 3. 
Result so far: 283.0
If we take 1272 away from 1505, we end up with 233.
Fetch the next digit (1) from the dividend, attach it to 233 and continue: 2331 / 424

Moving on to step 7:
2331 divided by 424 is 5 with a remainder of 211.
The next digit of our result is 5. 
Result so far: 2835.0
Subtracting 2120 from 2331 leaves us with 211.
Take the next digit (2) from the dividend and append it to 211, then repeat: 2112 / 424

Let's proceed to step 8:
424 can be fit into 2112 4 times, resulting in a remainder of 416.
The number 4 becomes the next digit in our result. 
Result so far: 28354.0
If we take 1696 away from 2112, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 9:
If we divide 4160 by 424, we get 9 and a remainder of 344.
Write down 9 as next digit of the result. 
Result so far: 28354.9
Subtracting 3816 from 4160 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 10:
424 goes into 3440 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 28354.98
The remainder is 48 after subtracting 3392 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
424 goes into 480 1 times with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 28354.981
Subtracting 424 from 480 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
424 goes into 560 1 times with a remainder of 136.
The next digit of our result is 1. 
Result so far: 28354.9811
Subtracting 424 from 560 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The quotient of the division is 28354.9811, and the remainder is 0.00136.
