We divide 87904547 by 427
The aim is to understand the frequency of 427 in 87904547.

On to step 1:
The number 427 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 427

Advancing to step 2:
The number 427 fits into 87 0 times, leaving a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 427

Let's proceed to step 3:
427 can be fit into 879 2 times, resulting in a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 854 from 879, we get 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 427

Moving on to step 4:
If we divide 250 by 427, we get 0 and a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 250 and we're left with 250.
Include the next digit (4) from the dividend after 250, then repeat: 2504 / 427

On to step 5:
The number 427 fits into 2504 5 times, leaving a remainder of 369.
Use 5 as the next digit of our solution. 
Result so far: 205.0
Deduct 2135 from 2504 and we're left with 369.
Fetch the next digit (5) from the dividend, attach it to 369 and continue: 3695 / 427

Moving on to step 6:
The number 427 fits into 3695 8 times, leaving a remainder of 279.
Write down 8 as next digit of the result. 
Result so far: 2058.0
If we subtract 3416 from 3695, we get 279.
Include the next digit (4) from the dividend after 279, then repeat: 2794 / 427

On to step 7:
427 can be fit into 2794 6 times, resulting in a remainder of 232.
The number 6 becomes the next digit in our result. 
Result so far: 20586.0
Subtract 2562 from 2794 to get 232.
Include the next digit (7) from the dividend after 232, then repeat: 2327 / 427

On to step 8:
The number 427 fits into 2327 5 times, leaving a remainder of 192.
The number 5 becomes the next digit in our result. 
Result so far: 205865.0
If we subtract 2135 from 2327, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 9:
When dividing 1920 by 427, we get 4 with a remainder of 212.
Record the quotient 4 as the next digit in the result. 
Result so far: 205865.4
Subtracting 1708 from 1920 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 10:
The number 427 fits into 2120 4 times, leaving a remainder of 412.
The next digit of our result is 4. 
Result so far: 205865.44
The remainder is 412 after subtracting 1708 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Our division results in 205865.44 with a remaining 0.412.
