We look at the division of 870002 by 29 
The aim is to understand the frequency of 29 in 870002.

Going ahead to step 1:
The number 29 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 29

Advancing to step 2:
87 divided by 29 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 87 from 87 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 29

Moving on to step 3:
0 divided by 29 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 29

Step 4:
When dividing 0 by 29, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 300.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 29

Advancing to step 5:
When dividing 0 by 29, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3000.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 29

Moving on to step 6:
When dividing 2 by 29, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 30000.0
Deduct 0 from 2 and we're left 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 7:
20 divided by 29 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 30000.0
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.

Moving on to step 8:
29 goes into 200 6 times with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 30000.06
If we take 174 away from 200, we end up 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.

Advancing to step 9:
29 can be fit into 260 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 30000.068
Deduct 232 from 260 and we're left 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.

Moving on to step 10:
The number 29 fits into 280 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 30000.0689
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.

On to step 11:
If we divide 190 by 29, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 30000.06896
The remainder is 16 after subtracting 174 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
The number 29 fits into 160 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 30000.068965
If we take 145 away from 160, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
150 divided by 29 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 30000.0689655
Subtract 145 from 150 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 30000.0689655 with a remaining 5e-08.
