We divide 30673476 by 221
The aim is to understand the frequency of 221 in 30673476.

Going ahead to step 1:
3 divided by 221 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 221

On to step 2:
221 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 221

Let's proceed to step 3:
When dividing 306 by 221, we get 1 with a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 221 from 306 leaves us with 85.
Append the next digit (7) from the dividend to 85 and continue with: 857 / 221

Advancing to step 4:
When dividing 857 by 221, we get 3 with a remainder of 194.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 663 from 857 and we're left with 194.
Append the next digit (3) from the dividend to 194 and continue with: 1943 / 221

Advancing to step 5:
If we divide 1943 by 221, we get 8 and a remainder of 175.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Subtract 1768 from 1943 to get 175.
Fetch the next digit (4) from the dividend, attach it to 175 and continue: 1754 / 221

Let's proceed to step 6:
The number 221 fits into 1754 7 times, leaving a remainder of 207.
The number 7 becomes the next digit in our result. 
Result so far: 1387.0
If we subtract 1547 from 1754, we get 207.
Bring next digit (7) of the dividend behind the 207 and repeat the process: 2077 / 221

Advancing to step 7:
If we divide 2077 by 221, we get 9 and a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 13879.0
Deduct 1989 from 2077 and we're left with 88.
Append the next digit (6) from the dividend to 88 and continue with: 886 / 221

On to step 8:
When dividing 886 by 221, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 138794.0
Deduct 884 from 886 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
221 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 138794.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
221 can be fit into 200 0 times, resulting in a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 138794.0
Deduct 0 from 200 and we're left 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.

The final result is 138794.0 with a remainder of 0.2.
