64427548 divided by 488 
The aim is to understand the frequency of 488 in 64427548.

Going ahead to step 1:
6 divided by 488 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 488

Going ahead to step 2:
64 divided by 488 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 488

On to step 3:
488 can be fit into 644 1 times, resulting in a remainder of 156.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 488 from 644 leaves us with 156.
Take the next digit (2) from the dividend and append it to 156, then repeat: 1562 / 488

Advancing to step 4:
488 goes into 1562 3 times with a remainder of 98.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1464 away from 1562, we end up with 98.
Take the next digit (7) from the dividend and append it to 98, then repeat: 987 / 488

Step 5:
When dividing 987 by 488, we get 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 132.0
If we subtract 976 from 987, we get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 488

Step 6:
115 divided by 488 is 0 with a remainder of 115.
The number 0 becomes the next digit in our result. 
Result so far: 1320.0
If we take 0 away from 115, we end up with 115.
Fetch the next digit (4) from the dividend, attach it to 115 and continue: 1154 / 488

Let's proceed to step 7:
When dividing 1154 by 488, we get 2 with a remainder of 178.
Use 2 as the next digit of our solution. 
Result so far: 13202.0
The remainder is 178 after subtracting 976 from 1154.
Grab the next digit (8) from the dividend, add it to 178, then carry on: 1788 / 488

On to step 8:
488 can be fit into 1788 3 times, resulting in a remainder of 324.
The number 3 becomes the next digit in our result. 
Result so far: 132023.0
If we take 1464 away from 1788, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 9:
When dividing 3240 by 488, we get 6 with a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 132023.6
Subtract 2928 from 3240 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 10:
If we divide 3120 by 488, we get 6 and a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 132023.66
If we subtract 2928 from 3120, 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.

After the division, we end up with 132023.66 and a remainder of 0.192.
