45117103 divided by 323 
The aim is to understand the frequency of 323 in 45117103.

On to step 1:
323 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 323

On to step 2:
The number 323 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 323

Moving on to step 3:
If we divide 451 by 323, we get 1 and a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 323 from 451 leaves us with 128.
Bring next digit (1) of the dividend behind the 128 and repeat the process: 1281 / 323

Moving on to step 4:
The number 323 fits into 1281 3 times, leaving a remainder of 312.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 969 from 1281, we get 312.
Append the next digit (7) from the dividend to 312 and continue with: 3127 / 323

Moving on to step 5:
3127 divided by 323 is 9 with a remainder of 220.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
The remainder is 220 after subtracting 2907 from 3127.
Bring next digit (1) of the dividend behind the 220 and repeat the process: 2201 / 323

Let's proceed to step 6:
If we divide 2201 by 323, we get 6 and a remainder of 263.
Put 6 as the next digit of the answer. 
Result so far: 1396.0
If we subtract 1938 from 2201, we get 263.
Include the next digit (0) from the dividend after 263, then repeat: 2630 / 323

Moving on to step 7:
The number 323 fits into 2630 8 times, leaving a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 13968.0
The remainder is 46 after subtracting 2584 from 2630.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 323

Moving on to step 8:
If we divide 463 by 323, we get 1 and a remainder of 140.
The next digit of our result is 1. 
Result so far: 139681.0
If we subtract 323 from 463, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 9:
When dividing 1400 by 323, we get 4 with a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 139681.4
Subtracting 1292 from 1400 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 10:
323 goes into 1080 3 times with a remainder of 111.
Put 3 as the next digit of the answer. 
Result so far: 139681.43
If we subtract 969 from 1080, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 11:
The number 323 fits into 1110 3 times, leaving a remainder of 141.
The next digit of our result is 3. 
Result so far: 139681.433
If we subtract 969 from 1110, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

The final result is 139681.433 with a remainder of 0.0141.
