We divide 624729 by 28
The aim is to understand the frequency of 28 in 624729.

Going ahead to step 1:
The number 28 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 28

Step 2:
When dividing 62 by 28, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 56 away from 62, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 28

Moving on to step 3:
64 divided by 28 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 56 from 64, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 28

Let's proceed to step 4:
28 can be fit into 87 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 223.0
The remainder is 3 after subtracting 84 from 87.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 28

Going ahead to step 5:
32 divided by 28 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 2231.0
If we take 28 away from 32, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 28

Moving on to step 6:
28 can be fit into 49 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 22311.0
Subtract 28 from 49 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
The number 28 fits into 210 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 22311.7
The remainder is 14 after subtracting 196 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
140 divided by 28 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 22311.75
Subtracting 140 from 140 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 28, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22311.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
28 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22311.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 22311.75, with a leftover of 0.0.
