We look at the division of 451499 by 29 
The aim is to understand the frequency of 29 in 451499.

On to step 1:
The number 29 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 29

On to step 2:
29 goes into 45 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 29 from 45 leaves us with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 29

Moving on to step 3:
The number 29 fits into 161 5 times, leaving a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 145 away from 161, we end up with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 29

Going ahead to step 4:
164 divided by 29 is 5 with a remainder of 19.
The next digit of our result is 5. 
Result so far: 155.0
Deduct 145 from 164 and we're left with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 29

Step 5:
If we divide 199 by 29, we get 6 and a remainder of 25.
The next digit of our result is 6. 
Result so far: 1556.0
Subtracting 174 from 199 leaves us with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 29

Advancing to step 6:
29 goes into 259 8 times with a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 15568.0
The remainder is 27 after subtracting 232 from 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
The number 29 fits into 270 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 15568.9
If we subtract 261 from 270, we 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.

Advancing to step 8:
When dividing 90 by 29, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 15568.93
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 9:
The number 29 fits into 30 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 15568.931
Deduct 29 from 30 and we're left 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.

Step 10:
10 divided by 29 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 15568.931
If we take 0 away from 10, we end up 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.

Going ahead to step 11:
When dividing 100 by 29, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 15568.93103
If we take 87 away from 100, we end up 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.

Step 12:
130 divided by 29 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 15568.931034
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 13:
29 goes into 140 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 15568.9310344
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 15568.9310344, with a leftover of 2.4e-07.
