We're dividing 77110725 by 604 
The aim is to understand the frequency of 604 in 77110725.

Advancing to step 1:
When dividing 7 by 604, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 604

On to step 2:
When dividing 77 by 604, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 604

Moving on to step 3:
The number 604 fits into 771 1 times, leaving a remainder of 167.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 604 away from 771, we end up with 167.
Bring next digit (1) of the dividend behind the 167 and repeat the process: 1671 / 604

Let's proceed to step 4:
If we divide 1671 by 604, we get 2 and a remainder of 463.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1208 away from 1671, we end up with 463.
Take the next digit (0) from the dividend and append it to 463, then repeat: 4630 / 604

Moving on to step 5:
604 goes into 4630 7 times with a remainder of 402.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we take 4228 away from 4630, we end up with 402.
Include the next digit (7) from the dividend after 402, then repeat: 4027 / 604

Going ahead to step 6:
When dividing 4027 by 604, we get 6 with a remainder of 403.
The next digit of our result is 6. 
Result so far: 1276.0
If we take 3624 away from 4027, we end up with 403.
Fetch the next digit (2) from the dividend, attach it to 403 and continue: 4032 / 604

Going ahead to step 7:
604 goes into 4032 6 times with a remainder of 408.
Put 6 as the next digit of the answer. 
Result so far: 12766.0
If we take 3624 away from 4032, we end up with 408.
Include the next digit (5) from the dividend after 408, then repeat: 4085 / 604

Step 8:
When dividing 4085 by 604, we get 6 with a remainder of 461.
Write down 6 as next digit of the result. 
Result so far: 127666.0
If we take 3624 away from 4085, we end up with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Step 9:
If we divide 4610 by 604, we get 7 and a remainder of 382.
Record the quotient 7 as the next digit in the result. 
Result so far: 127666.7
If we take 4228 away from 4610, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 10:
The number 604 fits into 3820 6 times, leaving a remainder of 196.
The number 6 becomes the next digit in our result. 
Result so far: 127666.76
Subtracting 3624 from 3820 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 11:
604 can be fit into 1960 3 times, resulting in a remainder of 148.
The number 3 becomes the next digit in our result. 
Result so far: 127666.763
Subtract 1812 from 1960 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 12:
604 can be fit into 1480 2 times, resulting in a remainder of 272.
Put 2 as the next digit of the answer. 
Result so far: 127666.7632
The remainder is 272 after subtracting 1208 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 13:
2720 divided by 604 is 4 with a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 127666.76324
Subtracting 2416 from 2720 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 14:
When dividing 3040 by 604, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 127666.763245
The remainder is 20 after subtracting 3020 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 15:
If we divide 200 by 604, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 127666.763245
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 16:
When dividing 2000 by 604, we get 3 with a remainder of 188.
The next digit of our result is 3. 
Result so far: 127666.76324503
If we take 1812 away from 2000, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The final result is 127666.76324503 with a remainder of 1.88e-07.
