66781 divided by 29 
The aim is to understand the frequency of 29 in 66781.

Advancing to step 1:
29 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 29

Moving on to step 2:
The number 29 fits into 66 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 58 from 66 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 29

Moving on to step 3:
29 can be fit into 87 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 87 from 87 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 29

Moving on to step 4:
29 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 230.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 29

Moving on to step 5:
81 divided by 29 is 2 with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 2302.0
Deduct 58 from 81 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 6:
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: 2302.7
Subtracting 203 from 230 leaves us with 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 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: 2302.79
Subtract 261 from 270 to 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.

Let's proceed to step 8:
90 divided by 29 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2302.793
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.

Moving on to 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: 2302.7931
Subtract 29 from 30 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to 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: 2302.7931
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.

Advancing to step 11:
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: 2302.793103
If we subtract 87 from 100, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
29 can be fit into 130 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 2302.7931034
Subtract 116 from 130 to get 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: 2302.79310344
Deduct 116 from 140 and we're left 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 2302.79310344, with a leftover of 2.4e-08.
