We're dividing 421481 by 29 
The aim is to understand the frequency of 29 in 421481.

Going ahead to step 1:
4 divided by 29 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 29

Going ahead to step 2:
29 goes into 42 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 13 after subtracting 29 from 42.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 29

Advancing to step 3:
If we divide 131 by 29, we get 4 and a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 116 from 131, we get 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 29

Going ahead to step 4:
154 divided by 29 is 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
Subtracting 145 from 154 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 29

Moving on to step 5:
When dividing 98 by 29, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 1453.0
If we subtract 87 from 98, we get 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 29

Going ahead to step 6:
If we divide 111 by 29, we get 3 and a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 14533.0
The remainder is 24 after subtracting 87 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
If we divide 240 by 29, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 14533.8
Subtracting 232 from 240 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
If we divide 80 by 29, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 14533.82
The remainder is 22 after subtracting 58 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
29 can be fit into 220 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 14533.827
If we take 203 away from 220, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
29 can be fit into 170 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 14533.8275
The remainder is 25 after subtracting 145 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
29 goes into 250 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 14533.82758
Subtract 232 from 250 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
The number 29 fits into 180 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 14533.827586
Subtracting 174 from 180 leaves us with 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 13:
29 goes into 60 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 14533.8275862
The remainder is 2 after subtracting 58 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
29 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 14533.8275862
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.

Our division results in 14533.8275862 with a remaining 2e-08.
