We divide 689644 by 29
The aim is to understand the frequency of 29 in 689644.

On to step 1:
If we divide 6 by 29, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 29

On to step 2:
When dividing 68 by 29, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 58 from 68 and we're left with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 29

Step 3:
If we divide 109 by 29, we get 3 and a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 87 away from 109, we end up with 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 29

On to step 4:
29 goes into 226 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 237.0
Deduct 203 from 226 and we're left with 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 29

Let's proceed to step 5:
If we divide 234 by 29, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 2378.0
If we subtract 232 from 234, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 29

Going ahead to step 6:
If we divide 24 by 29, we get 0 and a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 23780.0
If we subtract 0 from 24, we 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.

Going ahead to step 7:
When dividing 240 by 29, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 23780.8
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.

Moving on to step 8:
The number 29 fits into 80 2 times, leaving a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 23780.82
Deduct 58 from 80 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
When dividing 220 by 29, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 23780.827
If we subtract 203 from 220, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
The number 29 fits into 170 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 23780.8275
If we subtract 145 from 170, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
29 goes into 250 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 23780.82758
Deduct 232 from 250 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
29 can be fit into 180 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 23780.827586
Deduct 174 from 180 and we're left 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.

Advancing to step 13:
29 can be fit into 60 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 23780.8275862
If we take 58 away from 60, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
20 divided by 29 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 23780.8275862
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 23780.8275862 with a remainder of 2e-08.
