We look at the division of 642125 by 47 
The aim is to understand the frequency of 47 in 642125.

On to step 1:
47 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 47

On to step 2:
47 can be fit into 64 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 47 away from 64, we end up with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 47

Moving on to step 3:
If we divide 172 by 47, we get 3 and a remainder of 31.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 141 from 172, we get 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 47

Step 4:
311 divided by 47 is 6 with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
The remainder is 29 after subtracting 282 from 311.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 47

Going ahead to step 5:
The number 47 fits into 292 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 1366.0
If we subtract 282 from 292, we get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 47

On to step 6:
When dividing 105 by 47, we get 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 13662.0
Deduct 94 from 105 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
110 divided by 47 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 13662.2
If we take 94 away from 110, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
The number 47 fits into 160 3 times, leaving a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 13662.23
If we subtract 141 from 160, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
If we divide 190 by 47, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 13662.234
Subtracting 188 from 190 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
If we divide 20 by 47, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 13662.234
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
If we divide 200 by 47, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 13662.23404
If we subtract 188 from 200, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
47 can be fit into 120 2 times, resulting in a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 13662.234042
Deduct 94 from 120 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
260 divided by 47 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 13662.2340425
If we subtract 235 from 260, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
47 goes into 250 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 13662.23404255
If we take 235 away from 250, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 13662.23404255 with a remaining 1.5e-08.
