We're dividing 24751860 by 623 
The aim is to understand the frequency of 623 in 24751860.

On to step 1:
If we divide 2 by 623, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 623

Advancing to step 2:
If we divide 24 by 623, we get 0 and a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 623

Step 3:
The number 623 fits into 247 0 times, leaving a remainder of 247.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 247, we end up with 247.
Append the next digit (5) from the dividend to 247 and continue with: 2475 / 623

Advancing to step 4:
623 goes into 2475 3 times with a remainder of 606.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1869 from 2475 and we're left with 606.
Fetch the next digit (1) from the dividend, attach it to 606 and continue: 6061 / 623

Going ahead to step 5:
The number 623 fits into 6061 9 times, leaving a remainder of 454.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 5607 from 6061, we get 454.
Fetch the next digit (8) from the dividend, attach it to 454 and continue: 4548 / 623

Let's proceed to step 6:
If we divide 4548 by 623, we get 7 and a remainder of 187.
Record the quotient 7 as the next digit in the result. 
Result so far: 397.0
If we subtract 4361 from 4548, we get 187.
Append the next digit (6) from the dividend to 187 and continue with: 1876 / 623

Step 7:
The number 623 fits into 1876 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 3973.0
If we take 1869 away from 1876, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 623

On to step 8:
70 divided by 623 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 39730.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
If we divide 700 by 623, we get 1 and a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 39730.1
Subtract 623 from 700 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 10:
623 goes into 770 1 times with a remainder of 147.
Write down 1 as next digit of the result. 
Result so far: 39730.11
Subtract 623 from 770 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

In conclusion, the division gives 39730.11 with a balance of 0.147.
