78994608 ÷ 604 
The aim is to understand the frequency of 604 in 78994608.

Let's proceed to step 1:
If we divide 7 by 604, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 604

Going ahead to step 2:
78 divided by 604 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 604

Moving on to step 3:
604 can be fit into 789 1 times, resulting in a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 604 from 789 and we're left with 185.
Fetch the next digit (9) from the dividend, attach it to 185 and continue: 1859 / 604

Going ahead to step 4:
1859 divided by 604 is 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1812 from 1859 leaves us with 47.
Bring next digit (4) of the dividend behind the 47 and repeat the process: 474 / 604

On to step 5:
If we divide 474 by 604, we get 0 and a remainder of 474.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Deduct 0 from 474 and we're left with 474.
Include the next digit (6) from the dividend after 474, then repeat: 4746 / 604

Let's proceed to step 6:
The number 604 fits into 4746 7 times, leaving a remainder of 518.
Write down 7 as next digit of the result. 
Result so far: 1307.0
Subtract 4228 from 4746 to get 518.
Append the next digit (0) from the dividend to 518 and continue with: 5180 / 604

Going ahead to step 7:
604 can be fit into 5180 8 times, resulting in a remainder of 348.
Put 8 as the next digit of the answer. 
Result so far: 13078.0
Subtracting 4832 from 5180 leaves us with 348.
Fetch the next digit (8) from the dividend, attach it to 348 and continue: 3488 / 604

Advancing to step 8:
If we divide 3488 by 604, we get 5 and a remainder of 468.
Put 5 as the next digit of the answer. 
Result so far: 130785.0
If we take 3020 away from 3488, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 9:
The number 604 fits into 4680 7 times, leaving a remainder of 452.
The next digit of our result is 7. 
Result so far: 130785.7
Deduct 4228 from 4680 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 10:
604 can be fit into 4520 7 times, resulting in a remainder of 292.
Use 7 as the next digit of our solution. 
Result so far: 130785.77
Subtracting 4228 from 4520 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

The quotient of the division is 130785.77, and the remainder is 0.292.
