631780 ÷ 24 
The aim is to understand the frequency of 24 in 631780.

On to step 1:
6 divided by 24 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 24

Advancing to step 2:
24 goes into 63 2 times with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 15 after subtracting 48 from 63.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 24

On to step 3:
The number 24 fits into 151 6 times, leaving a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we subtract 144 from 151, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 24

Moving on to step 4:
24 goes into 77 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 263.0
If we take 72 away from 77, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 24

On to step 5:
If we divide 58 by 24, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2632.0
Subtracting 48 from 58 leaves us with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 24

Step 6:
If we divide 100 by 24, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 26324.0
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
When dividing 40 by 24, we get 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 26324.1
Subtract 24 from 40 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
24 goes into 160 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 26324.16
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
160 divided by 24 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 26324.166
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 26324.166 with a remainder of 0.0016.
