We look at the division of 629617 by 29 
The aim is to understand the frequency of 29 in 629617.

Advancing to step 1:
6 divided by 29 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 29

Going ahead to step 2:
If we divide 62 by 29, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 58 away from 62, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 29

On to step 3:
29 goes into 49 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 29 from 49 leaves us with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 29

Moving on to step 4:
If we divide 206 by 29, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 217.0
The remainder is 3 after subtracting 203 from 206.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 29

Moving on to step 5:
31 divided by 29 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 2171.0
Subtract 29 from 31 to get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 29

Moving on to step 6:
29 can be fit into 27 0 times, resulting in a remainder of 27.
The next digit of our result is 0. 
Result so far: 21710.0
Subtract 0 from 27 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.

On to step 7:
The number 29 fits into 270 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 21710.9
The remainder is 9 after subtracting 261 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
29 goes into 90 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 21710.93
If we subtract 87 from 90, we 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 9:
29 can be fit into 30 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21710.931
The remainder is 1 after subtracting 29 from 30.
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:
29 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 21710.931
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.

Going ahead to step 11:
The number 29 fits into 100 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 21710.93103
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.

Advancing to step 12:
If we divide 130 by 29, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 21710.931034
Subtracting 116 from 130 leaves us 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.

Moving on to step 13:
29 can be fit into 140 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 21710.9310344
The remainder is 24 after subtracting 116 from 140.
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 result is 21710.9310344 with a remainder of 2.4e-07.
