811421 divided by 29 
The aim is to understand the frequency of 29 in 811421.

Going ahead to step 1:
29 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 29

Advancing to step 2:
29 can be fit into 81 2 times, resulting in a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 58 from 81 leaves us with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 29

Advancing to step 3:
The number 29 fits into 231 7 times, leaving a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 203 from 231 and we're left with 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 29

Going ahead to step 4:
When dividing 284 by 29, we get 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 279.0
If we take 261 away from 284, we end up with 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 29

Let's proceed to step 5:
29 can be fit into 232 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 2798.0
If we take 232 away from 232, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 29

On to step 6:
29 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 27980.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 29 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 27980.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
29 goes into 100 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 27980.03
Deduct 87 from 100 and we're left 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.

Moving on to step 9:
130 divided by 29 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 27980.034
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.

Let's proceed to step 10:
When dividing 140 by 29, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 27980.0344
Subtract 116 from 140 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 27980.0344, with a leftover of 0.00024.
