We're dividing 135123 by 44 
The aim is to understand the frequency of 44 in 135123.

Advancing to step 1:
44 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 44

Let's proceed to step 2:
13 divided by 44 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 44

Moving on to step 3:
The number 44 fits into 135 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 132 from 135 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 44

Advancing to step 4:
The number 44 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 44

Let's proceed to step 5:
44 goes into 312 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 307.0
If we take 308 away from 312, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 44

Let's proceed to step 6:
44 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 3070.0
Subtract 0 from 43 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
If we divide 430 by 44, we get 9 and a remainder of 34.
The next digit of our result is 9. 
Result so far: 3070.9
The remainder is 34 after subtracting 396 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
44 goes into 340 7 times with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 3070.97
Subtract 308 from 340 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
320 divided by 44 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 3070.977
The remainder is 12 after subtracting 308 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 3070.977 with a remaining 0.0012.
