Let's divide 7938470 by 494
The aim is to understand the frequency of 494 in 7938470.

Going ahead to step 1:
7 divided by 494 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 494

Going ahead to step 2:
When dividing 79 by 494, we get 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Fetch the next digit (3) from the dividend, attach it to 79 and continue: 793 / 494

Advancing to step 3:
When dividing 793 by 494, we get 1 with a remainder of 299.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 494 from 793 and we're left with 299.
Take the next digit (8) from the dividend and append it to 299, then repeat: 2998 / 494

Advancing to step 4:
If we divide 2998 by 494, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 2964 from 2998, we get 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 494

Moving on to step 5:
If we divide 344 by 494, we get 0 and a remainder of 344.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
Subtracting 0 from 344 leaves us with 344.
Include the next digit (7) from the dividend after 344, then repeat: 3447 / 494

On to step 6:
494 goes into 3447 6 times with a remainder of 483.
The next digit of our result is 6. 
Result so far: 1606.0
Subtracting 2964 from 3447 leaves us with 483.
Append the next digit (0) from the dividend to 483 and continue with: 4830 / 494

Moving on to step 7:
When dividing 4830 by 494, we get 9 with a remainder of 384.
Put 9 as the next digit of the answer. 
Result so far: 16069.0
Subtract 4446 from 4830 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 8:
494 goes into 3840 7 times with a remainder of 382.
Record the quotient 7 as the next digit in the result. 
Result so far: 16069.7
Subtract 3458 from 3840 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 9:
When dividing 3820 by 494, we get 7 with a remainder of 362.
The number 7 becomes the next digit in our result. 
Result so far: 16069.77
If we subtract 3458 from 3820, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The final outcome is 16069.77, with a leftover of 0.362.
