551866 divided by 29 
The aim is to understand the frequency of 29 in 551866.

Step 1:
29 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 29

On to step 2:
29 goes into 55 1 times with a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 29 from 55, we get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 29

Let's proceed to step 3:
29 can be fit into 261 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 261 from 261 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 29

On to step 4:
If we divide 8 by 29, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 190.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 29

Advancing to step 5:
86 divided by 29 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 1902.0
If we take 58 away from 86, we end up with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 29

Going ahead to step 6:
286 divided by 29 is 9 with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 19029.0
If we subtract 261 from 286, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
29 goes into 250 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 19029.8
Deduct 232 from 250 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
The number 29 fits into 180 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 19029.86
If we subtract 174 from 180, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
60 divided by 29 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 19029.862
Subtract 58 from 60 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
29 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 19029.862
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 29, we get 6 with a remainder of 26.
The next digit of our result is 6. 
Result so far: 19029.86206
The remainder is 26 after subtracting 174 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
The number 29 fits into 260 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 19029.862068
If we take 232 away from 260, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
280 divided by 29 is 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 19029.8620689
Subtract 261 from 280 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
29 goes into 190 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 19029.86206896
Deduct 174 from 190 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 19029.86206896 with a remaining 1.6e-08.
