80977737 ÷ 604 
The aim is to understand the frequency of 604 in 80977737.

Step 1:
The number 604 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 604

On to step 2:
If we divide 80 by 604, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 604

Going ahead to step 3:
If we divide 809 by 604, we get 1 and a remainder of 205.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 205 after subtracting 604 from 809.
Append the next digit (7) from the dividend to 205 and continue with: 2057 / 604

Let's proceed to step 4:
If we divide 2057 by 604, we get 3 and a remainder of 245.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1812 from 2057 to get 245.
Bring next digit (7) of the dividend behind the 245 and repeat the process: 2457 / 604

Step 5:
The number 604 fits into 2457 4 times, leaving a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtract 2416 from 2457 to get 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 604

Going ahead to step 6:
If we divide 417 by 604, we get 0 and a remainder of 417.
Write down 0 as next digit of the result. 
Result so far: 1340.0
If we subtract 0 from 417, we get 417.
Take the next digit (3) from the dividend and append it to 417, then repeat: 4173 / 604

Moving on to step 7:
604 goes into 4173 6 times with a remainder of 549.
Record the quotient 6 as the next digit in the result. 
Result so far: 13406.0
Subtract 3624 from 4173 to get 549.
Append the next digit (7) from the dividend to 549 and continue with: 5497 / 604

On to step 8:
5497 divided by 604 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 134069.0
If we take 5436 away from 5497, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
If we divide 610 by 604, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 134069.1
The remainder is 6 after subtracting 604 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
604 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 134069.1
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
When dividing 600 by 604, we get 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 134069.1
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 134069.1 with a remainder of 0.06.
