We're dividing 171628 by 47 
The aim is to understand the frequency of 47 in 171628.

On to step 1:
1 divided by 47 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 47

On to step 2:
When dividing 17 by 47, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 47

Moving on to step 3:
171 divided by 47 is 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 141 from 171, we get 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 47

Let's proceed to step 4:
47 goes into 306 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtracting 282 from 306 leaves us with 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 47

On to step 5:
242 divided by 47 is 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 365.0
Subtracting 235 from 242 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 47

Moving on to step 6:
47 goes into 78 1 times with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 3651.0
Subtract 47 from 78 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.

On to step 7:
47 goes into 310 6 times with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 3651.6
If we subtract 282 from 310, we 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.

Advancing to step 8:
If we divide 280 by 47, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 3651.65
Deduct 235 from 280 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
450 divided by 47 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 3651.659
Subtract 423 from 450 to 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.

On to step 10:
270 divided by 47 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 3651.6595
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.

Step 11:
350 divided by 47 is 7 with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 3651.65957
Deduct 329 from 350 and we're left 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.

Let's proceed to step 12:
210 divided by 47 is 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 3651.659574
Deduct 188 from 210 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
47 goes into 220 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 3651.6595744
Subtract 188 from 220 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 3651.6595744 with a remaining 3.2e-07.
