We look at the division of 78334788 by 291 
The aim is to understand the frequency of 291 in 78334788.

Advancing to step 1:
291 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 291

Going ahead to step 2:
When dividing 78 by 291, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 291

Moving on to step 3:
If we divide 783 by 291, we get 2 and a remainder of 201.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 582 away from 783, we end up with 201.
Take the next digit (3) from the dividend and append it to 201, then repeat: 2013 / 291

On to step 4:
291 can be fit into 2013 6 times, resulting in a remainder of 267.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 1746 from 2013 to get 267.
Append the next digit (4) from the dividend to 267 and continue with: 2674 / 291

Going ahead to step 5:
If we divide 2674 by 291, we get 9 and a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 269.0
The remainder is 55 after subtracting 2619 from 2674.
Grab the next digit (7) from the dividend, add it to 55, then carry on: 557 / 291

Advancing to step 6:
557 divided by 291 is 1 with a remainder of 266.
The number 1 becomes the next digit in our result. 
Result so far: 2691.0
Deduct 291 from 557 and we're left with 266.
Include the next digit (8) from the dividend after 266, then repeat: 2668 / 291

Moving on to step 7:
The number 291 fits into 2668 9 times, leaving a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 26919.0
The remainder is 49 after subtracting 2619 from 2668.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 291

Advancing to step 8:
291 goes into 498 1 times with a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 269191.0
If we take 291 away from 498, 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.

Advancing to step 9:
291 goes into 2070 7 times with a remainder of 33.
The next digit of our result is 7. 
Result so far: 269191.7
Deduct 2037 from 2070 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
If we divide 330 by 291, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 269191.71
Subtracting 291 from 330 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 11:
291 can be fit into 390 1 times, resulting in a remainder of 99.
Use 1 as the next digit of our solution. 
Result so far: 269191.711
Subtracting 291 from 390 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Our division results in 269191.711 with a remaining 0.0099.
