We look at the division of 815657 by 29 
The aim is to understand the frequency of 29 in 815657.

Step 1:
If we divide 8 by 29, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 29

Moving on to step 2:
81 divided by 29 is 2 with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 58 from 81 and we're left with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 29

Let's proceed to step 3:
When dividing 235 by 29, we get 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 232 from 235, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 29

Moving on to step 4:
If we divide 36 by 29, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 281.0
Subtract 29 from 36 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 29

Going ahead to step 5:
29 goes into 75 2 times with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2812.0
Subtracting 58 from 75 leaves us with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 29

Step 6:
177 divided by 29 is 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 28126.0
Deduct 174 from 177 and we're left 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.

Going ahead to step 7:
When dividing 30 by 29, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 28126.1
If we subtract 29 from 30, we 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.

Moving on to step 8:
When dividing 10 by 29, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 28126.1
Subtract 0 from 10 to get 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 9:
If we divide 100 by 29, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 28126.103
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.

On to step 10:
29 goes into 130 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 28126.1034
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.

Going ahead to step 11:
The number 29 fits into 140 4 times, leaving a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 28126.10344
Subtract 116 from 140 to 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.

The quotient of the division is 28126.10344, and the remainder is 2.4e-05.
