We look at the division of 57664 by 29 
The aim is to understand the frequency of 29 in 57664.

Step 1:
When dividing 5 by 29, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 29

Going ahead to step 2:
57 divided by 29 is 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 29 from 57 leaves us with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 29

Going ahead to step 3:
When dividing 286 by 29, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 25 after subtracting 261 from 286.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 29

Advancing to step 4:
When dividing 256 by 29, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 198.0
Subtract 232 from 256 to get 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 29

Moving on to step 5:
29 can be fit into 244 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1988.0
Deduct 232 from 244 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.

Advancing to step 6:
120 divided by 29 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 1988.4
If we take 116 away from 120, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
29 can be fit into 40 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1988.41
If we take 29 away from 40, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
If we divide 110 by 29, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 1988.413
Deduct 87 from 110 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
The number 29 fits into 230 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 1988.4137
If we take 203 away from 230, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
29 can be fit into 270 9 times, resulting in a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 1988.41379
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
90 divided by 29 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 1988.413793
If we take 87 away from 90, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
29 goes into 30 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1988.4137931
If we take 29 away from 30, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
29 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1988.4137931
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 1988.4137931 with a remainder of 1e-08.
