521875 divided by 29 
The aim is to understand the frequency of 29 in 521875.

On to step 1:
When dividing 5 by 29, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 29

Let's proceed to step 2:
If we divide 52 by 29, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 29 from 52 and we're left with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 29

Step 3:
231 divided by 29 is 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 203 from 231 leaves us with 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 29

Let's proceed to step 4:
29 can be fit into 288 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 179.0
If we subtract 261 from 288, we get 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 29

Let's proceed to step 5:
The number 29 fits into 277 9 times, leaving a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 1799.0
Deduct 261 from 277 and we're left with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 29

Going ahead to step 6:
If we divide 165 by 29, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 17995.0
Subtract 145 from 165 to 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.

Going ahead to step 7:
If we divide 200 by 29, we get 6 and a remainder of 26.
The next digit of our result is 6. 
Result so far: 17995.6
Subtracting 174 from 200 leaves us with 26.
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 8:
If we divide 260 by 29, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 17995.68
Subtract 232 from 260 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
29 goes into 280 9 times with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 17995.689
Deduct 261 from 280 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
29 goes into 190 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 17995.6896
Subtract 174 from 190 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 29 fits into 160 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 17995.68965
The remainder is 15 after subtracting 145 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
29 goes into 150 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 17995.689655
Subtract 145 from 150 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 17995.689655, with a leftover of 5e-07.
