We look at the division of 74701179 by 604 
The aim is to understand the frequency of 604 in 74701179.

On to step 1:
604 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 604

Advancing to step 2:
If we divide 74 by 604, we get 0 and a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Fetch the next digit (7) from the dividend, attach it to 74 and continue: 747 / 604

Moving on to step 3:
747 divided by 604 is 1 with a remainder of 143.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 143 after subtracting 604 from 747.
Append the next digit (0) from the dividend to 143 and continue with: 1430 / 604

Advancing to step 4:
The number 604 fits into 1430 2 times, leaving a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1208 from 1430, we get 222.
Grab the next digit (1) from the dividend, add it to 222, then carry on: 2221 / 604

Step 5:
When dividing 2221 by 604, we get 3 with a remainder of 409.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
The remainder is 409 after subtracting 1812 from 2221.
Fetch the next digit (1) from the dividend, attach it to 409 and continue: 4091 / 604

Moving on to step 6:
604 can be fit into 4091 6 times, resulting in a remainder of 467.
The next digit of our result is 6. 
Result so far: 1236.0
The remainder is 467 after subtracting 3624 from 4091.
Fetch the next digit (7) from the dividend, attach it to 467 and continue: 4677 / 604

Step 7:
604 goes into 4677 7 times with a remainder of 449.
The number 7 becomes the next digit in our result. 
Result so far: 12367.0
If we subtract 4228 from 4677, we get 449.
Grab the next digit (9) from the dividend, add it to 449, then carry on: 4499 / 604

On to step 8:
The number 604 fits into 4499 7 times, leaving a remainder of 271.
The next digit of our result is 7. 
Result so far: 123677.0
If we take 4228 away from 4499, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 9:
When dividing 2710 by 604, we get 4 with a remainder of 294.
The number 4 becomes the next digit in our result. 
Result so far: 123677.4
Deduct 2416 from 2710 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 10:
If we divide 2940 by 604, we get 4 and a remainder of 524.
Use 4 as the next digit of our solution. 
Result so far: 123677.44
Subtracting 2416 from 2940 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

The quotient of the division is 123677.44, and the remainder is 0.524.
