876421 divided by 47 
The aim is to understand the frequency of 47 in 876421.

Step 1:
When dividing 8 by 47, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 47

Moving on to step 2:
47 goes into 87 1 times with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 40 after subtracting 47 from 87.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 47

On to step 3:
If we divide 406 by 47, we get 8 and a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 30 after subtracting 376 from 406.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 47

On to step 4:
304 divided by 47 is 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 186.0
The remainder is 22 after subtracting 282 from 304.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 47

Going ahead to step 5:
47 goes into 222 4 times with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 1864.0
Deduct 188 from 222 and we're left with 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 47

Let's proceed to step 6:
341 divided by 47 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 18647.0
The remainder is 12 after subtracting 329 from 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
120 divided by 47 is 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 18647.2
Subtract 94 from 120 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
260 divided by 47 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 18647.25
Deduct 235 from 260 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
47 can be fit into 250 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 18647.255
If we subtract 235 from 250, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 18647.255 and a remainder of 0.0015.
