680357 divided by 29 
The aim is to understand the frequency of 29 in 680357.

On to step 1:
The number 29 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 29

Moving on to step 2:
When dividing 68 by 29, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
If we take 58 away from 68, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 29

Let's proceed to step 3:
29 can be fit into 100 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 87 from 100 and we're left with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 29

Advancing to step 4:
133 divided by 29 is 4 with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 234.0
If we subtract 116 from 133, we get 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 29

Advancing to step 5:
The number 29 fits into 175 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 2346.0
Subtract 174 from 175 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 29

Let's proceed to step 6:
29 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 23460.0
Deduct 0 from 17 and we're left 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.

Going ahead to step 7:
29 goes into 170 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 23460.5
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.

Going ahead to step 8:
250 divided by 29 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 23460.58
If we subtract 232 from 250, we 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.

Going ahead to step 9:
If we divide 180 by 29, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 23460.586
If we take 174 away from 180, we end up 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 10:
The number 29 fits into 60 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 23460.5862
If we subtract 58 from 60, we get 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 11:
The number 29 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 23460.5862
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
200 divided by 29 is 6 with a remainder of 26.
The next digit of our result is 6. 
Result so far: 23460.586206
Subtracting 174 from 200 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
260 divided by 29 is 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 23460.5862068
Subtracting 232 from 260 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
If we divide 280 by 29, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 23460.58620689
Deduct 261 from 280 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 23460.58620689, with a leftover of 1.9e-08.
