Let's divide 91669730 by 223
The aim is to understand the frequency of 223 in 91669730.

Moving on to step 1:
When dividing 9 by 223, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 223

On to step 2:
If we divide 91 by 223, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Take the next digit (6) from the dividend and append it to 91, then repeat: 916 / 223

Step 3:
916 divided by 223 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 892 from 916, we get 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 223

Moving on to step 4:
If we divide 246 by 223, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 41.0
If we subtract 223 from 246, we get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 223

Let's proceed to step 5:
223 goes into 239 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 411.0
If we subtract 223 from 239, we get 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 223

Moving on to step 6:
167 divided by 223 is 0 with a remainder of 167.
The number 0 becomes the next digit in our result. 
Result so far: 4110.0
If we take 0 away from 167, we end up with 167.
Take the next digit (3) from the dividend and append it to 167, then repeat: 1673 / 223

Moving on to step 7:
1673 divided by 223 is 7 with a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 41107.0
Deduct 1561 from 1673 and we're left with 112.
Take the next digit (0) from the dividend and append it to 112, then repeat: 1120 / 223

On to step 8:
1120 divided by 223 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 411075.0
If we take 1115 away from 1120, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
The number 223 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 411075.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
223 goes into 500 2 times with a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 411075.02
Deduct 446 from 500 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
540 divided by 223 is 2 with a remainder of 94.
Use 2 as the next digit of our solution. 
Result so far: 411075.022
If we subtract 446 from 540, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final result is 411075.022 with a remainder of 0.0094.
