We're dividing 405661 by 47 
The aim is to understand the frequency of 47 in 405661.

Step 1:
When dividing 4 by 47, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 47

Going ahead to step 2:
The number 47 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 47

Advancing to step 3:
When dividing 405 by 47, we get 8 with a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 376 from 405 leaves us with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 47

On to step 4:
The number 47 fits into 296 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 86.0
Subtracting 282 from 296 leaves us with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 47

Moving on to step 5:
47 goes into 146 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 863.0
Subtracting 141 from 146 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 47

Going ahead to step 6:
51 divided by 47 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 8631.0
If we take 47 away from 51, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
If we divide 40 by 47, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8631.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
47 can be fit into 400 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 8631.08
Subtracting 376 from 400 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
47 goes into 240 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8631.085
If we subtract 235 from 240, we 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.

Moving on to step 10:
When dividing 50 by 47, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 8631.0851
Subtract 47 from 50 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
If we divide 30 by 47, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 8631.0851
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
The number 47 fits into 300 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 8631.085106
Subtract 282 from 300 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
47 goes into 180 3 times with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 8631.0851063
If we take 141 away from 180, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 14:
47 can be fit into 390 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 8631.08510638
Deduct 376 from 390 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 8631.08510638 and a remainder of 1.4e-08.
