We look at the division of 29286027 by 291 
The aim is to understand the frequency of 291 in 29286027.

Moving on to step 1:
The number 291 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 291

Going ahead to step 2:
291 goes into 29 0 times with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 291

On to step 3:
291 goes into 292 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 291 from 292, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 291

Advancing to step 4:
The number 291 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 18, we end up with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 291

Advancing to step 5:
The number 291 fits into 186 0 times, leaving a remainder of 186.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 186 and we're left with 186.
Grab the next digit (0) from the dividend, add it to 186, then carry on: 1860 / 291

Let's proceed to step 6:
The number 291 fits into 1860 6 times, leaving a remainder of 114.
Write down 6 as next digit of the result. 
Result so far: 1006.0
Subtracting 1746 from 1860 leaves us with 114.
Fetch the next digit (2) from the dividend, attach it to 114 and continue: 1142 / 291

Going ahead to step 7:
291 can be fit into 1142 3 times, resulting in a remainder of 269.
The number 3 becomes the next digit in our result. 
Result so far: 10063.0
Subtract 873 from 1142 to get 269.
Fetch the next digit (7) from the dividend, attach it to 269 and continue: 2697 / 291

On to step 8:
If we divide 2697 by 291, we get 9 and a remainder of 78.
The next digit of our result is 9. 
Result so far: 100639.0
If we take 2619 away from 2697, 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.

Going ahead to step 9:
If we divide 780 by 291, we get 2 and a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 100639.2
If we take 582 away from 780, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 10:
The number 291 fits into 1980 6 times, leaving a remainder of 234.
The number 6 becomes the next digit in our result. 
Result so far: 100639.26
The remainder is 234 after subtracting 1746 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 11:
291 goes into 2340 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 100639.268
Deduct 2328 from 2340 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
If we divide 120 by 291, we get 0 and a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 100639.268
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 13:
291 can be fit into 1200 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 100639.26804
Deduct 1164 from 1200 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
The number 291 fits into 360 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 100639.268041
If we take 291 away from 360, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 15:
If we divide 690 by 291, we get 2 and a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 100639.2680412
If we subtract 582 from 690, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 16:
1080 divided by 291 is 3 with a remainder of 207.
The next digit of our result is 3. 
Result so far: 100639.26804123
If we take 873 away from 1080, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

After the division, we end up with 100639.26804123 and a remainder of 2.07e-07.
