We look at the division of 810217 by 47 
The aim is to understand the frequency of 47 in 810217.

Step 1:
The number 47 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 47

On to step 2:
47 can be fit into 81 1 times, resulting in a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 47 from 81 leaves us with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 47

On to step 3:
When dividing 340 by 47, we get 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 329 from 340 to get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 47

Step 4:
47 goes into 112 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Deduct 94 from 112 and we're left with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 47

Let's proceed to step 5:
If we divide 181 by 47, we get 3 and a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 1723.0
Subtract 141 from 181 to get 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 47

Moving on to step 6:
If we divide 407 by 47, we get 8 and a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 17238.0
Subtract 376 from 407 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
When dividing 310 by 47, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 17238.6
Subtract 282 from 310 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
47 goes into 280 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 17238.65
Subtract 235 from 280 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
When dividing 450 by 47, we get 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 17238.659
If we subtract 423 from 450, we get 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 10:
47 goes into 270 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 17238.6595
Subtracting 235 from 270 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
The number 47 fits into 350 7 times, leaving a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 17238.65957
If we take 329 away from 350, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 12:
The number 47 fits into 210 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 17238.659574
The remainder is 22 after subtracting 188 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
47 goes into 220 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 17238.6595744
The remainder is 32 after subtracting 188 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 17238.6595744 and a remainder of 3.2e-07.
