We look at the division of 84123356 by 844 
The aim is to understand the frequency of 844 in 84123356.

Moving on to step 1:
The number 844 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 844

Let's proceed to step 2:
844 can be fit into 84 0 times, resulting in a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Grab the next digit (1) from the dividend, add it to 84, then carry on: 841 / 844

Going ahead to step 3:
841 divided by 844 is 0 with a remainder of 841.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 841 after subtracting 0 from 841.
Include the next digit (2) from the dividend after 841, then repeat: 8412 / 844

Advancing to step 4:
The number 844 fits into 8412 9 times, leaving a remainder of 816.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 7596 from 8412, we get 816.
Take the next digit (3) from the dividend and append it to 816, then repeat: 8163 / 844

Going ahead to step 5:
844 can be fit into 8163 9 times, resulting in a remainder of 567.
Use 9 as the next digit of our solution. 
Result so far: 99.0
The remainder is 567 after subtracting 7596 from 8163.
Grab the next digit (3) from the dividend, add it to 567, then carry on: 5673 / 844

Advancing to step 6:
844 can be fit into 5673 6 times, resulting in a remainder of 609.
Use 6 as the next digit of our solution. 
Result so far: 996.0
If we subtract 5064 from 5673, we get 609.
Include the next digit (5) from the dividend after 609, then repeat: 6095 / 844

Let's proceed to step 7:
When dividing 6095 by 844, we get 7 with a remainder of 187.
The next digit of our result is 7. 
Result so far: 9967.0
Subtract 5908 from 6095 to get 187.
Include the next digit (6) from the dividend after 187, then repeat: 1876 / 844

Going ahead to step 8:
844 goes into 1876 2 times with a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 99672.0
Subtracting 1688 from 1876 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 9:
If we divide 1880 by 844, we get 2 and a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 99672.2
If we subtract 1688 from 1880, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 10:
When dividing 1920 by 844, we get 2 with a remainder of 232.
The next digit of our result is 2. 
Result so far: 99672.22
If we subtract 1688 from 1920, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Our division results in 99672.22 with a remaining 0.232.
