12309840 ÷ 494 
The aim is to understand the frequency of 494 in 12309840.

Advancing to step 1:
1 divided by 494 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 494

Let's proceed to step 2:
12 divided by 494 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 494

On to step 3:
494 goes into 123 0 times with a remainder of 123.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 123 and we're left with 123.
Append the next digit (0) from the dividend to 123 and continue with: 1230 / 494

Step 4:
When dividing 1230 by 494, we get 2 with a remainder of 242.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 988 from 1230 leaves us with 242.
Bring next digit (9) of the dividend behind the 242 and repeat the process: 2429 / 494

Step 5:
494 goes into 2429 4 times with a remainder of 453.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 1976 from 2429, we get 453.
Append the next digit (8) from the dividend to 453 and continue with: 4538 / 494

Moving on to step 6:
4538 divided by 494 is 9 with a remainder of 92.
Record the quotient 9 as the next digit in the result. 
Result so far: 249.0
The remainder is 92 after subtracting 4446 from 4538.
Bring next digit (4) of the dividend behind the 92 and repeat the process: 924 / 494

Moving on to step 7:
494 goes into 924 1 times with a remainder of 430.
Write down 1 as next digit of the result. 
Result so far: 2491.0
Subtracting 494 from 924 leaves us with 430.
Fetch the next digit (0) from the dividend, attach it to 430 and continue: 4300 / 494

Going ahead to step 8:
494 can be fit into 4300 8 times, resulting in a remainder of 348.
The number 8 becomes the next digit in our result. 
Result so far: 24918.0
The remainder is 348 after subtracting 3952 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 9:
The number 494 fits into 3480 7 times, leaving a remainder of 22.
The next digit of our result is 7. 
Result so far: 24918.7
If we subtract 3458 from 3480, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
When dividing 220 by 494, we get 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 24918.7
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 11:
494 can be fit into 2200 4 times, resulting in a remainder of 224.
Use 4 as the next digit of our solution. 
Result so far: 24918.704
Deduct 1976 from 2200 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 12:
494 goes into 2240 4 times with a remainder of 264.
The next digit of our result is 4. 
Result so far: 24918.7044
Deduct 1976 from 2240 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

In conclusion, the division gives 24918.7044 with a balance of 0.00264.
