406993 ÷ 24 
The aim is to understand the frequency of 24 in 406993.

Step 1:
24 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 24

Moving on to step 2:
The number 24 fits into 40 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 24 from 40 and we're left with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 24

Step 3:
166 divided by 24 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 144 from 166, we get 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 24

Let's proceed to step 4:
If we divide 229 by 24, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 169.0
Subtracting 216 from 229 leaves us with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 24

Moving on to step 5:
If we divide 139 by 24, we get 5 and a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 1695.0
The remainder is 19 after subtracting 120 from 139.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 24

Let's proceed to step 6:
When dividing 193 by 24, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 16958.0
If we subtract 192 from 193, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 24, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 16958.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
24 goes into 100 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 16958.04
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 24 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 16958.041
If we subtract 24 from 40, we 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.

Step 10:
24 goes into 160 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 16958.0416
Subtracting 144 from 160 leaves us 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.

Advancing to step 11:
160 divided by 24 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 16958.04166
Subtract 144 from 160 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.

The final result is 16958.04166 with a remainder of 1.6e-05.
