We divide 45221347 by 123
The aim is to understand the frequency of 123 in 45221347.

Advancing to step 1:
The number 123 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 123

Going ahead to step 2:
45 divided by 123 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 123

Step 3:
452 divided by 123 is 3 with a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 369 from 452 leaves us with 83.
Append the next digit (2) from the dividend to 83 and continue with: 832 / 123

Step 4:
123 can be fit into 832 6 times, resulting in a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 738 from 832 and we're left with 94.
Take the next digit (1) from the dividend and append it to 94, then repeat: 941 / 123

Step 5:
941 divided by 123 is 7 with a remainder of 80.
The number 7 becomes the next digit in our result. 
Result so far: 367.0
If we take 861 away from 941, we end up with 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 123

Moving on to step 6:
803 divided by 123 is 6 with a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 3676.0
If we subtract 738 from 803, we get 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 123

Going ahead to step 7:
123 can be fit into 654 5 times, resulting in a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 36765.0
The remainder is 39 after subtracting 615 from 654.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 123

On to step 8:
123 goes into 397 3 times with a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 367653.0
Subtract 369 from 397 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
If we divide 280 by 123, we get 2 and a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 367653.2
Subtracting 246 from 280 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
The number 123 fits into 340 2 times, leaving a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 367653.22
If we subtract 246 from 340, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final outcome is 367653.22, with a leftover of 0.094.
