We look at the division of 33919072 by 123 
The aim is to understand the frequency of 123 in 33919072.

Moving on to step 1:
The number 123 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 123

Moving on to step 2:
When dividing 33 by 123, we get 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 123

Step 3:
339 divided by 123 is 2 with a remainder of 93.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 246 from 339 to get 93.
Include the next digit (1) from the dividend after 93, then repeat: 931 / 123

Step 4:
123 can be fit into 931 7 times, resulting in a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 861 from 931 and we're left with 70.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 123

Moving on to step 5:
The number 123 fits into 709 5 times, leaving a remainder of 94.
Record the quotient 5 as the next digit in the result. 
Result so far: 275.0
Deduct 615 from 709 and we're left with 94.
Bring next digit (0) of the dividend behind the 94 and repeat the process: 940 / 123

Let's proceed to step 6:
940 divided by 123 is 7 with a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 2757.0
If we take 861 away from 940, we end up with 79.
Append the next digit (7) from the dividend to 79 and continue with: 797 / 123

On to step 7:
123 can be fit into 797 6 times, resulting in a remainder of 59.
Put 6 as the next digit of the answer. 
Result so far: 27576.0
Subtract 738 from 797 to get 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 123

Moving on to step 8:
If we divide 592 by 123, we get 4 and a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 275764.0
Deduct 492 from 592 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 9:
123 can be fit into 1000 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 275764.8
Subtracting 984 from 1000 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
123 goes into 160 1 times with a remainder of 37.
The next digit of our result is 1. 
Result so far: 275764.81
The remainder is 37 after subtracting 123 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
370 divided by 123 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 275764.813
Subtracting 369 from 370 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
The number 123 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 275764.813
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
The number 123 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 275764.813
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 275764.813, with a leftover of 0.0001.
