74994923 divided by 604 
The aim is to understand the frequency of 604 in 74994923.

Advancing to step 1:
7 divided by 604 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 (4) from the dividend, attach it to 7 and continue: 74 / 604

Let's proceed to step 2:
604 can be fit into 74 0 times, resulting in a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 604

Step 3:
749 divided by 604 is 1 with a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 604 from 749 leaves us with 145.
Bring next digit (9) of the dividend behind the 145 and repeat the process: 1459 / 604

Moving on to step 4:
1459 divided by 604 is 2 with a remainder of 251.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1208 away from 1459, we end up with 251.
Include the next digit (4) from the dividend after 251, then repeat: 2514 / 604

Advancing to step 5:
If we divide 2514 by 604, we get 4 and a remainder of 98.
The next digit of our result is 4. 
Result so far: 124.0
Subtract 2416 from 2514 to get 98.
Bring next digit (9) of the dividend behind the 98 and repeat the process: 989 / 604

Going ahead to step 6:
604 can be fit into 989 1 times, resulting in a remainder of 385.
The next digit of our result is 1. 
Result so far: 1241.0
Subtracting 604 from 989 leaves us with 385.
Take the next digit (2) from the dividend and append it to 385, then repeat: 3852 / 604

Let's proceed to step 7:
The number 604 fits into 3852 6 times, leaving a remainder of 228.
Put 6 as the next digit of the answer. 
Result so far: 12416.0
If we subtract 3624 from 3852, we get 228.
Append the next digit (3) from the dividend to 228 and continue with: 2283 / 604

Moving on to step 8:
2283 divided by 604 is 3 with a remainder of 471.
The number 3 becomes the next digit in our result. 
Result so far: 124163.0
The remainder is 471 after subtracting 1812 from 2283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Step 9:
604 can be fit into 4710 7 times, resulting in a remainder of 482.
Record the quotient 7 as the next digit in the result. 
Result so far: 124163.7
If we subtract 4228 from 4710, we get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 10:
The number 604 fits into 4820 7 times, leaving a remainder of 592.
Record the quotient 7 as the next digit in the result. 
Result so far: 124163.77
If we take 4228 away from 4820, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

The final outcome is 124163.77, with a leftover of 0.592.
