We're dividing 300463 by 29 
The aim is to understand the frequency of 29 in 300463.

Advancing to step 1:
When dividing 3 by 29, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 29

Moving on to step 2:
29 goes into 30 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 29 from 30, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 29

Advancing to step 3:
If we divide 10 by 29, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 29

Moving on to step 4:
When dividing 104 by 29, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we take 87 away from 104, we end up with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 29

Moving on to step 5:
If we divide 176 by 29, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 1036.0
Subtracting 174 from 176 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 29

Going ahead to step 6:
29 can be fit into 23 0 times, resulting in a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 10360.0
If we subtract 0 from 23, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
The number 29 fits into 230 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 10360.7
Subtract 203 from 230 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
When dividing 270 by 29, we get 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 10360.79
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.

Step 9:
90 divided by 29 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 10360.793
Subtract 87 from 90 to get 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 10:
30 divided by 29 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 10360.7931
Subtracting 29 from 30 leaves us 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.

On to step 11:
29 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10360.7931
The remainder is 10 after subtracting 0 from 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 12:
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: 10360.793103
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.

Moving on to step 13:
130 divided by 29 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 10360.7931034
Deduct 116 from 130 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
If we divide 140 by 29, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 10360.79310344
Subtracting 116 from 140 leaves us with 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 10360.79310344, with a leftover of 2.4e-08.
