We're dividing 725006 by 623 
The aim is to understand the frequency of 623 in 725006.

Moving on to step 1:
623 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 623

On to step 2:
72 divided by 623 is 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Fetch the next digit (5) from the dividend, attach it to 72 and continue: 725 / 623

Moving on to step 3:
The number 623 fits into 725 1 times, leaving a remainder of 102.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 623 from 725 to get 102.
Fetch the next digit (0) from the dividend, attach it to 102 and continue: 1020 / 623

Step 4:
If we divide 1020 by 623, we get 1 and a remainder of 397.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 623 from 1020 and we're left with 397.
Bring next digit (0) of the dividend behind the 397 and repeat the process: 3970 / 623

On to step 5:
If we divide 3970 by 623, we get 6 and a remainder of 232.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Deduct 3738 from 3970 and we're left with 232.
Include the next digit (6) from the dividend after 232, then repeat: 2326 / 623

Moving on to step 6:
When dividing 2326 by 623, we get 3 with a remainder of 457.
Record the quotient 3 as the next digit in the result. 
Result so far: 1163.0
Deduct 1869 from 2326 and we're left with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Step 7:
The number 623 fits into 4570 7 times, leaving a remainder of 209.
The number 7 becomes the next digit in our result. 
Result so far: 1163.7
If we subtract 4361 from 4570, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 8:
The number 623 fits into 2090 3 times, leaving a remainder of 221.
The next digit of our result is 3. 
Result so far: 1163.73
Deduct 1869 from 2090 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 9:
623 can be fit into 2210 3 times, resulting in a remainder of 341.
Use 3 as the next digit of our solution. 
Result so far: 1163.733
If we take 1869 away from 2210, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

The final outcome is 1163.733, with a leftover of 0.0341.
