Let's divide 91770022 by 304
The aim is to understand the frequency of 304 in 91770022.

Advancing to step 1:
When dividing 9 by 304, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 304

On to step 2:
When dividing 91 by 304, we get 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Append the next digit (7) from the dividend to 91 and continue with: 917 / 304

Step 3:
When dividing 917 by 304, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 912 from 917 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 304

Advancing to step 4:
The number 304 fits into 57 0 times, leaving a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 57, we get 57.
Grab the next digit (0) from the dividend, add it to 57, then carry on: 570 / 304

Moving on to step 5:
The number 304 fits into 570 1 times, leaving a remainder of 266.
Record the quotient 1 as the next digit in the result. 
Result so far: 301.0
The remainder is 266 after subtracting 304 from 570.
Grab the next digit (0) from the dividend, add it to 266, then carry on: 2660 / 304

Step 6:
304 goes into 2660 8 times with a remainder of 228.
Put 8 as the next digit of the answer. 
Result so far: 3018.0
If we subtract 2432 from 2660, we get 228.
Take the next digit (2) from the dividend and append it to 228, then repeat: 2282 / 304

Advancing to step 7:
The number 304 fits into 2282 7 times, leaving a remainder of 154.
Use 7 as the next digit of our solution. 
Result so far: 30187.0
Subtract 2128 from 2282 to get 154.
Bring next digit (2) of the dividend behind the 154 and repeat the process: 1542 / 304

Advancing to step 8:
304 can be fit into 1542 5 times, resulting in a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 301875.0
Subtract 1520 from 1542 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
304 goes into 220 0 times with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 301875.0
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
2200 divided by 304 is 7 with a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 301875.07
Subtracting 2128 from 2200 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
If we divide 720 by 304, we get 2 and a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 301875.072
The remainder is 112 after subtracting 608 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
If we divide 1120 by 304, we get 3 and a remainder of 208.
Write down 3 as next digit of the result. 
Result so far: 301875.0723
Deduct 912 from 1120 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 13:
304 goes into 2080 6 times with a remainder of 256.
The number 6 becomes the next digit in our result. 
Result so far: 301875.07236
Subtracting 1824 from 2080 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 14:
2560 divided by 304 is 8 with a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 301875.072368
Subtract 2432 from 2560 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 15:
304 can be fit into 1280 4 times, resulting in a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 301875.0723684
If we take 1216 away from 1280, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 16:
When dividing 640 by 304, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 301875.07236842
Subtracting 608 from 640 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 301875.07236842 and a remainder of 3.2e-08.
