We're dividing 644185 by 47 
The aim is to understand the frequency of 47 in 644185.

On to step 1:
The number 47 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 47

Advancing to step 2:
The number 47 fits into 64 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 17 after subtracting 47 from 64.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 47

On to step 3:
47 can be fit into 174 3 times, resulting in a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 33 after subtracting 141 from 174.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 47

Going ahead to step 4:
If we divide 331 by 47, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Deduct 329 from 331 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 47

Advancing to step 5:
28 divided by 47 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 1370.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 47

Let's proceed to step 6:
If we divide 285 by 47, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 13706.0
The remainder is 3 after subtracting 282 from 285.
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 7:
The number 47 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 13706.0
Subtracting 0 from 30 leaves us with 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 8:
If we divide 300 by 47, we get 6 and a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 13706.06
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.

Step 9:
The number 47 fits into 180 3 times, leaving a remainder of 39.
The next digit of our result is 3. 
Result so far: 13706.063
Subtract 141 from 180 to get 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 10:
47 goes into 390 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 13706.0638
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.

Let's proceed to step 11:
140 divided by 47 is 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 13706.06382
If we subtract 94 from 140, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
The number 47 fits into 460 9 times, leaving a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 13706.063829
The remainder is 37 after subtracting 423 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 13:
47 can be fit into 370 7 times, resulting in a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 13706.0638297
Deduct 329 from 370 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 14:
410 divided by 47 is 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 13706.06382978
If we take 376 away from 410, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 13706.06382978, with a leftover of 3.4e-08.
