48878693 divided by 604 
The aim is to understand the frequency of 604 in 48878693.

Let's proceed to step 1:
When dividing 4 by 604, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 604

Advancing to step 2:
When dividing 48 by 604, we get 0 with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 604

Going ahead to step 3:
488 divided by 604 is 0 with a remainder of 488.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 488 to get 488.
Bring next digit (7) of the dividend behind the 488 and repeat the process: 4887 / 604

Step 4:
The number 604 fits into 4887 8 times, leaving a remainder of 55.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 55 after subtracting 4832 from 4887.
Fetch the next digit (8) from the dividend, attach it to 55 and continue: 558 / 604

Advancing to step 5:
604 can be fit into 558 0 times, resulting in a remainder of 558.
Use 0 as the next digit of our solution. 
Result so far: 80.0
The remainder is 558 after subtracting 0 from 558.
Append the next digit (6) from the dividend to 558 and continue with: 5586 / 604

Advancing to step 6:
5586 divided by 604 is 9 with a remainder of 150.
Write down 9 as next digit of the result. 
Result so far: 809.0
The remainder is 150 after subtracting 5436 from 5586.
Take the next digit (9) from the dividend and append it to 150, then repeat: 1509 / 604

On to step 7:
604 goes into 1509 2 times with a remainder of 301.
Record the quotient 2 as the next digit in the result. 
Result so far: 8092.0
Deduct 1208 from 1509 and we're left with 301.
Take the next digit (3) from the dividend and append it to 301, then repeat: 3013 / 604

Advancing to step 8:
604 goes into 3013 4 times with a remainder of 597.
Record the quotient 4 as the next digit in the result. 
Result so far: 80924.0
The remainder is 597 after subtracting 2416 from 3013.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Step 9:
604 can be fit into 5970 9 times, resulting in a remainder of 534.
The number 9 becomes the next digit in our result. 
Result so far: 80924.9
Deduct 5436 from 5970 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 10:
If we divide 5340 by 604, we get 8 and a remainder of 508.
Put 8 as the next digit of the answer. 
Result so far: 80924.98
If we subtract 4832 from 5340, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Advancing to step 11:
604 can be fit into 5080 8 times, resulting in a remainder of 248.
Write down 8 as next digit of the result. 
Result so far: 80924.988
If we subtract 4832 from 5080, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final outcome is 80924.988, with a leftover of 0.0248.
