We look at the division of 73042564 by 494 
The aim is to understand the frequency of 494 in 73042564.

On to step 1:
494 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 494

Going ahead to step 2:
494 can be fit into 73 0 times, resulting in a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 494

On to step 3:
If we divide 730 by 494, we get 1 and a remainder of 236.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 494 from 730 and we're left with 236.
Include the next digit (4) from the dividend after 236, then repeat: 2364 / 494

Step 4:
If we divide 2364 by 494, we get 4 and a remainder of 388.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 1976 away from 2364, we end up with 388.
Include the next digit (2) from the dividend after 388, then repeat: 3882 / 494

Going ahead to step 5:
494 goes into 3882 7 times with a remainder of 424.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Subtract 3458 from 3882 to get 424.
Grab the next digit (5) from the dividend, add it to 424, then carry on: 4245 / 494

Let's proceed to step 6:
494 goes into 4245 8 times with a remainder of 293.
Put 8 as the next digit of the answer. 
Result so far: 1478.0
Subtract 3952 from 4245 to get 293.
Append the next digit (6) from the dividend to 293 and continue with: 2936 / 494

Going ahead to step 7:
2936 divided by 494 is 5 with a remainder of 466.
Record the quotient 5 as the next digit in the result. 
Result so far: 14785.0
If we take 2470 away from 2936, we end up with 466.
Include the next digit (4) from the dividend after 466, then repeat: 4664 / 494

Step 8:
When dividing 4664 by 494, we get 9 with a remainder of 218.
The next digit of our result is 9. 
Result so far: 147859.0
The remainder is 218 after subtracting 4446 from 4664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 9:
494 can be fit into 2180 4 times, resulting in a remainder of 204.
Put 4 as the next digit of the answer. 
Result so far: 147859.4
If we subtract 1976 from 2180, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 10:
494 goes into 2040 4 times with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 147859.44
The remainder is 64 after subtracting 1976 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 147859.44, with a leftover of 0.064.
