29966224 ÷ 857 
The aim is to understand the frequency of 857 in 29966224.

Going ahead to step 1:
If we divide 2 by 857, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 857

Let's proceed to step 2:
29 divided by 857 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 857

Moving on to step 3:
299 divided by 857 is 0 with a remainder of 299.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 299, we get 299.
Take the next digit (6) from the dividend and append it to 299, then repeat: 2996 / 857

Let's proceed to step 4:
If we divide 2996 by 857, we get 3 and a remainder of 425.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 425 after subtracting 2571 from 2996.
Fetch the next digit (6) from the dividend, attach it to 425 and continue: 4256 / 857

Let's proceed to step 5:
When dividing 4256 by 857, we get 4 with a remainder of 828.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 3428 from 4256 leaves us with 828.
Include the next digit (2) from the dividend after 828, then repeat: 8282 / 857

Step 6:
8282 divided by 857 is 9 with a remainder of 569.
The number 9 becomes the next digit in our result. 
Result so far: 349.0
Deduct 7713 from 8282 and we're left with 569.
Take the next digit (2) from the dividend and append it to 569, then repeat: 5692 / 857

Going ahead to step 7:
857 can be fit into 5692 6 times, resulting in a remainder of 550.
Write down 6 as next digit of the result. 
Result so far: 3496.0
Subtract 5142 from 5692 to get 550.
Take the next digit (4) from the dividend and append it to 550, then repeat: 5504 / 857

Let's proceed to step 8:
5504 divided by 857 is 6 with a remainder of 362.
The next digit of our result is 6. 
Result so far: 34966.0
The remainder is 362 after subtracting 5142 from 5504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 9:
857 goes into 3620 4 times with a remainder of 192.
The next digit of our result is 4. 
Result so far: 34966.4
If we take 3428 away from 3620, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 10:
When dividing 1920 by 857, we get 2 with a remainder of 206.
Record the quotient 2 as the next digit in the result. 
Result so far: 34966.42
Subtract 1714 from 1920 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 11:
The number 857 fits into 2060 2 times, leaving a remainder of 346.
Use 2 as the next digit of our solution. 
Result so far: 34966.422
Subtract 1714 from 2060 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

The final result is 34966.422 with a remainder of 0.0346.
