We look at the division of 81176994 by 291 
The aim is to understand the frequency of 291 in 81176994.

Going ahead to step 1:
If we divide 8 by 291, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 291

Step 2:
The number 291 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 291

On to step 3:
291 can be fit into 811 2 times, resulting in a remainder of 229.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 582 from 811 to get 229.
Take the next digit (7) from the dividend and append it to 229, then repeat: 2297 / 291

Let's proceed to step 4:
When dividing 2297 by 291, we get 7 with a remainder of 260.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 2037 from 2297 and we're left with 260.
Include the next digit (6) from the dividend after 260, then repeat: 2606 / 291

Let's proceed to step 5:
If we divide 2606 by 291, we get 8 and a remainder of 278.
Record the quotient 8 as the next digit in the result. 
Result so far: 278.0
Subtracting 2328 from 2606 leaves us with 278.
Append the next digit (9) from the dividend to 278 and continue with: 2789 / 291

Let's proceed to step 6:
2789 divided by 291 is 9 with a remainder of 170.
The next digit of our result is 9. 
Result so far: 2789.0
The remainder is 170 after subtracting 2619 from 2789.
Fetch the next digit (9) from the dividend, attach it to 170 and continue: 1709 / 291

Let's proceed to step 7:
1709 divided by 291 is 5 with a remainder of 254.
The number 5 becomes the next digit in our result. 
Result so far: 27895.0
Subtract 1455 from 1709 to get 254.
Append the next digit (4) from the dividend to 254 and continue with: 2544 / 291

Advancing to step 8:
When dividing 2544 by 291, we get 8 with a remainder of 216.
Put 8 as the next digit of the answer. 
Result so far: 278958.0
If we subtract 2328 from 2544, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 9:
291 can be fit into 2160 7 times, resulting in a remainder of 123.
Record the quotient 7 as the next digit in the result. 
Result so far: 278958.7
If we subtract 2037 from 2160, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 10:
291 can be fit into 1230 4 times, resulting in a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 278958.74
If we take 1164 away from 1230, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
291 can be fit into 660 2 times, resulting in a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 278958.742
If we take 582 away from 660, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 12:
If we divide 780 by 291, we get 2 and a remainder of 198.
Record the quotient 2 as the next digit in the result. 
Result so far: 278958.7422
If we subtract 582 from 780, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

In conclusion, the division gives 278958.7422 with a balance of 0.00198.
