Let's divide 64573025 by 624
The aim is to understand the frequency of 624 in 64573025.

Moving on to step 1:
624 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 624

Moving on to step 2:
If we divide 64 by 624, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 624

Advancing to step 3:
When dividing 645 by 624, we get 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 624 from 645 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 624

Advancing to step 4:
624 goes into 217 0 times with a remainder of 217.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 217, we get 217.
Fetch the next digit (3) from the dividend, attach it to 217 and continue: 2173 / 624

Going ahead to step 5:
When dividing 2173 by 624, we get 3 with a remainder of 301.
The next digit of our result is 3. 
Result so far: 103.0
If we subtract 1872 from 2173, we get 301.
Fetch the next digit (0) from the dividend, attach it to 301 and continue: 3010 / 624

Going ahead to step 6:
The number 624 fits into 3010 4 times, leaving a remainder of 514.
Use 4 as the next digit of our solution. 
Result so far: 1034.0
If we take 2496 away from 3010, we end up with 514.
Take the next digit (2) from the dividend and append it to 514, then repeat: 5142 / 624

On to step 7:
The number 624 fits into 5142 8 times, leaving a remainder of 150.
Record the quotient 8 as the next digit in the result. 
Result so far: 10348.0
The remainder is 150 after subtracting 4992 from 5142.
Append the next digit (5) from the dividend to 150 and continue with: 1505 / 624

Going ahead to step 8:
If we divide 1505 by 624, we get 2 and a remainder of 257.
Put 2 as the next digit of the answer. 
Result so far: 103482.0
The remainder is 257 after subtracting 1248 from 1505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 9:
624 can be fit into 2570 4 times, resulting in a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 103482.4
Subtract 2496 from 2570 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
If we divide 740 by 624, we get 1 and a remainder of 116.
Use 1 as the next digit of our solution. 
Result so far: 103482.41
Subtracting 624 from 740 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 11:
624 goes into 1160 1 times with a remainder of 536.
The next digit of our result is 1. 
Result so far: 103482.411
Subtract 624 from 1160 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

After the division, we end up with 103482.411 and a remainder of 0.0536.
