181686 ÷ 47 
The aim is to understand the frequency of 47 in 181686.

On to step 1:
47 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 47

Moving on to step 2:
When dividing 18 by 47, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 47

Moving on to step 3:
The number 47 fits into 181 3 times, leaving a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 141 from 181 leaves us with 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 47

Let's proceed to step 4:
When dividing 406 by 47, we get 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 376 from 406 to get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 47

Going ahead to step 5:
If we divide 308 by 47, we get 6 and a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 386.0
Subtract 282 from 308 to get 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 47

Going ahead to step 6:
47 goes into 266 5 times with a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 3865.0
Subtract 235 from 266 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.

Step 7:
310 divided by 47 is 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 3865.6
Subtracting 282 from 310 leaves us 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.

Advancing to step 8:
If we divide 280 by 47, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 3865.65
Subtracting 235 from 280 leaves us 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.

Let's proceed to step 9:
450 divided by 47 is 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 3865.659
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.

Going ahead to step 10:
The number 47 fits into 270 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3865.6595
The remainder is 35 after subtracting 235 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
When dividing 350 by 47, we get 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 3865.65957
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.

Going ahead to step 12:
The number 47 fits into 210 4 times, leaving a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 3865.659574
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.

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: 3865.6595744
If we subtract 188 from 220, we 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.

After the division, we end up with 3865.6595744 and a remainder of 3.2e-07.
