We're dividing 39768981 by 488 
The aim is to understand the frequency of 488 in 39768981.

Let's proceed to step 1:
488 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 488

Going ahead to step 2:
If we divide 39 by 488, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 488

Going ahead to step 3:
When dividing 397 by 488, we get 0 with a remainder of 397.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 397 and we're left with 397.
Append the next digit (6) from the dividend to 397 and continue with: 3976 / 488

Advancing to step 4:
The number 488 fits into 3976 8 times, leaving a remainder of 72.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 72 after subtracting 3904 from 3976.
Append the next digit (8) from the dividend to 72 and continue with: 728 / 488

Advancing to step 5:
728 divided by 488 is 1 with a remainder of 240.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtracting 488 from 728 leaves us with 240.
Take the next digit (9) from the dividend and append it to 240, then repeat: 2409 / 488

Going ahead to step 6:
488 goes into 2409 4 times with a remainder of 457.
Put 4 as the next digit of the answer. 
Result so far: 814.0
Subtracting 1952 from 2409 leaves us with 457.
Include the next digit (8) from the dividend after 457, then repeat: 4578 / 488

Going ahead to step 7:
4578 divided by 488 is 9 with a remainder of 186.
Put 9 as the next digit of the answer. 
Result so far: 8149.0
The remainder is 186 after subtracting 4392 from 4578.
Grab the next digit (1) from the dividend, add it to 186, then carry on: 1861 / 488

Moving on to step 8:
488 can be fit into 1861 3 times, resulting in a remainder of 397.
The number 3 becomes the next digit in our result. 
Result so far: 81493.0
The remainder is 397 after subtracting 1464 from 1861.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

On to step 9:
If we divide 3970 by 488, we get 8 and a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 81493.8
Deduct 3904 from 3970 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
488 can be fit into 660 1 times, resulting in a remainder of 172.
Record the quotient 1 as the next digit in the result. 
Result so far: 81493.81
Subtract 488 from 660 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
If we divide 1720 by 488, we get 3 and a remainder of 256.
Record the quotient 3 as the next digit in the result. 
Result so far: 81493.813
The remainder is 256 after subtracting 1464 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 12:
If we divide 2560 by 488, we get 5 and a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 81493.8135
If we take 2440 away from 2560, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 13:
1200 divided by 488 is 2 with a remainder of 224.
Write down 2 as next digit of the result. 
Result so far: 81493.81352
The remainder is 224 after subtracting 976 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 14:
When dividing 2240 by 488, we get 4 with a remainder of 288.
Write down 4 as next digit of the result. 
Result so far: 81493.813524
Deduct 1952 from 2240 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 15:
488 goes into 2880 5 times with a remainder of 440.
Write down 5 as next digit of the result. 
Result so far: 81493.8135245
Subtract 2440 from 2880 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 16:
The number 488 fits into 4400 9 times, leaving a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 81493.81352459
Subtract 4392 from 4400 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 81493.81352459 with a remaining 8e-09.
