67752109 ÷ 291 
The aim is to understand the frequency of 291 in 67752109.

Step 1:
291 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 291

Step 2:
When dividing 67 by 291, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Include the next digit (7) from the dividend after 67, then repeat: 677 / 291

On to step 3:
677 divided by 291 is 2 with a remainder of 95.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 582 from 677 and we're left with 95.
Fetch the next digit (5) from the dividend, attach it to 95 and continue: 955 / 291

Moving on to step 4:
955 divided by 291 is 3 with a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 873 from 955 and we're left with 82.
Bring next digit (2) of the dividend behind the 82 and repeat the process: 822 / 291

Step 5:
The number 291 fits into 822 2 times, leaving a remainder of 240.
The next digit of our result is 2. 
Result so far: 232.0
Deduct 582 from 822 and we're left with 240.
Include the next digit (1) from the dividend after 240, then repeat: 2401 / 291

Step 6:
2401 divided by 291 is 8 with a remainder of 73.
Use 8 as the next digit of our solution. 
Result so far: 2328.0
Subtract 2328 from 2401 to get 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 291

On to step 7:
730 divided by 291 is 2 with a remainder of 148.
The next digit of our result is 2. 
Result so far: 23282.0
The remainder is 148 after subtracting 582 from 730.
Include the next digit (9) from the dividend after 148, then repeat: 1489 / 291

Advancing to step 8:
291 can be fit into 1489 5 times, resulting in a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 232825.0
The remainder is 34 after subtracting 1455 from 1489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
If we divide 340 by 291, we get 1 and a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 232825.1
If we subtract 291 from 340, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 10:
291 can be fit into 490 1 times, resulting in a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 232825.11
The remainder is 199 after subtracting 291 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

The final outcome is 232825.11, with a leftover of 0.199.
