We look at the division of 863861 by 29 
The aim is to understand the frequency of 29 in 863861.

Step 1:
When dividing 8 by 29, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 29

Advancing to step 2:
If we divide 86 by 29, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 58 from 86, we get 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 29

Advancing to step 3:
If we divide 283 by 29, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 22 after subtracting 261 from 283.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 29

Going ahead to step 4:
When dividing 228 by 29, we get 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 297.0
Subtract 203 from 228 to get 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 29

Step 5:
256 divided by 29 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 2978.0
Deduct 232 from 256 and we're left with 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 29

Step 6:
If we divide 241 by 29, we get 8 and a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 29788.0
Subtracting 232 from 241 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
29 goes into 90 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 29788.3
If we take 87 away from 90, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
29 can be fit into 30 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 29788.31
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.

Going ahead to step 9:
10 divided by 29 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 29788.31
If we take 0 away from 10, we end up with 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 10:
If we divide 100 by 29, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 29788.3103
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.

Advancing to step 11:
29 goes into 130 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 29788.31034
If we take 116 away from 130, we end up 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.

Advancing to step 12:
140 divided by 29 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 29788.310344
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.

After the division, we end up with 29788.310344 and a remainder of 2.4e-06.
