81589863 divided by 488 
The aim is to understand the frequency of 488 in 81589863.

Going ahead to step 1:
488 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 488

Let's proceed to step 2:
When dividing 81 by 488, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 488

Let's proceed to step 3:
The number 488 fits into 815 1 times, leaving a remainder of 327.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 488 from 815 to get 327.
Fetch the next digit (8) from the dividend, attach it to 327 and continue: 3278 / 488

Moving on to step 4:
488 goes into 3278 6 times with a remainder of 350.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 2928 from 3278 and we're left with 350.
Append the next digit (9) from the dividend to 350 and continue with: 3509 / 488

Advancing to step 5:
488 goes into 3509 7 times with a remainder of 93.
Write down 7 as next digit of the result. 
Result so far: 167.0
Subtracting 3416 from 3509 leaves us with 93.
Include the next digit (8) from the dividend after 93, then repeat: 938 / 488

Let's proceed to step 6:
If we divide 938 by 488, we get 1 and a remainder of 450.
Put 1 as the next digit of the answer. 
Result so far: 1671.0
If we take 488 away from 938, we end up with 450.
Take the next digit (6) from the dividend and append it to 450, then repeat: 4506 / 488

Let's proceed to step 7:
488 goes into 4506 9 times with a remainder of 114.
The next digit of our result is 9. 
Result so far: 16719.0
If we take 4392 away from 4506, we end up with 114.
Take the next digit (3) from the dividend and append it to 114, then repeat: 1143 / 488

Step 8:
488 can be fit into 1143 2 times, resulting in a remainder of 167.
Write down 2 as next digit of the result. 
Result so far: 167192.0
If we subtract 976 from 1143, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 9:
488 goes into 1670 3 times with a remainder of 206.
Put 3 as the next digit of the answer. 
Result so far: 167192.3
Deduct 1464 from 1670 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 10:
When dividing 2060 by 488, we get 4 with a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 167192.34
The remainder is 108 after subtracting 1952 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 11:
1080 divided by 488 is 2 with a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 167192.342
The remainder is 104 after subtracting 976 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 12:
488 goes into 1040 2 times with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 167192.3422
Deduct 976 from 1040 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 167192.3422 with a remainder of 0.00064.
