Let's divide 81996788 by 29
The aim is to understand the frequency of 29 in 81996788.

On to step 1:
The number 29 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 29

Moving on to step 2:
29 can be fit into 81 2 times, resulting in a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 58 from 81 to get 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 29

On to step 3:
29 goes into 239 8 times with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtracting 232 from 239 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 29

Let's proceed to step 4:
If we divide 79 by 29, we get 2 and a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 282.0
If we subtract 58 from 79, we get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 29

Advancing to step 5:
216 divided by 29 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 2827.0
If we subtract 203 from 216, we get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 29

Going ahead to step 6:
137 divided by 29 is 4 with a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 28274.0
Deduct 116 from 137 and we're left with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 29

Going ahead to step 7:
29 can be fit into 218 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 282747.0
If we take 203 away from 218, we end up with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 29

Advancing to step 8:
29 can be fit into 158 5 times, resulting in a remainder of 13.
The next digit of our result is 5. 
Result so far: 2827475.0
Subtracting 145 from 158 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
130 divided by 29 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 2827475.4
The remainder is 14 after subtracting 116 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
140 divided by 29 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 2827475.44
Subtracting 116 from 140 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 2827475.44 with a remaining 0.024.
