We're dividing 87254921 by 427 
The aim is to understand the frequency of 427 in 87254921.

Advancing to step 1:
427 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 427

On to step 2:
The number 427 fits into 87 0 times, leaving a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Fetch the next digit (2) from the dividend, attach it to 87 and continue: 872 / 427

Advancing to step 3:
427 goes into 872 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 854 away from 872, we end up with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 427

Let's proceed to step 4:
427 goes into 185 0 times with a remainder of 185.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 185 to get 185.
Include the next digit (4) from the dividend after 185, then repeat: 1854 / 427

Let's proceed to step 5:
When dividing 1854 by 427, we get 4 with a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 204.0
If we take 1708 away from 1854, we end up with 146.
Grab the next digit (9) from the dividend, add it to 146, then carry on: 1469 / 427

Advancing to step 6:
If we divide 1469 by 427, we get 3 and a remainder of 188.
Record the quotient 3 as the next digit in the result. 
Result so far: 2043.0
Subtract 1281 from 1469 to get 188.
Take the next digit (2) from the dividend and append it to 188, then repeat: 1882 / 427

Moving on to step 7:
The number 427 fits into 1882 4 times, leaving a remainder of 174.
Use 4 as the next digit of our solution. 
Result so far: 20434.0
Deduct 1708 from 1882 and we're left with 174.
Fetch the next digit (1) from the dividend, attach it to 174 and continue: 1741 / 427

Going ahead to step 8:
The number 427 fits into 1741 4 times, leaving a remainder of 33.
The next digit of our result is 4. 
Result so far: 204344.0
Subtracting 1708 from 1741 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
330 divided by 427 is 0 with a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 204344.0
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 10:
When dividing 3300 by 427, we get 7 with a remainder of 311.
Use 7 as the next digit of our solution. 
Result so far: 204344.07
Subtract 2989 from 3300 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 11:
427 goes into 3110 7 times with a remainder of 121.
Record the quotient 7 as the next digit in the result. 
Result so far: 204344.077
If we take 2989 away from 3110, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

The final result is 204344.077 with a remainder of 0.0121.
