We look at the division of 83271495 by 648 
The aim is to understand the frequency of 648 in 83271495.

Advancing to step 1:
When dividing 8 by 648, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 648

On to step 2:
If we divide 83 by 648, we get 0 and a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Grab the next digit (2) from the dividend, add it to 83, then carry on: 832 / 648

Moving on to step 3:
648 goes into 832 1 times with a remainder of 184.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 648 from 832 leaves us with 184.
Bring next digit (7) of the dividend behind the 184 and repeat the process: 1847 / 648

Moving on to step 4:
If we divide 1847 by 648, we get 2 and a remainder of 551.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1296 from 1847 leaves us with 551.
Take the next digit (1) from the dividend and append it to 551, then repeat: 5511 / 648

On to step 5:
The number 648 fits into 5511 8 times, leaving a remainder of 327.
The next digit of our result is 8. 
Result so far: 128.0
Subtract 5184 from 5511 to get 327.
Append the next digit (4) from the dividend to 327 and continue with: 3274 / 648

Moving on to step 6:
648 goes into 3274 5 times with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 1285.0
Subtracting 3240 from 3274 leaves us with 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 648

On to step 7:
The number 648 fits into 349 0 times, leaving a remainder of 349.
The number 0 becomes the next digit in our result. 
Result so far: 12850.0
Subtract 0 from 349 to get 349.
Include the next digit (5) from the dividend after 349, then repeat: 3495 / 648

Step 8:
3495 divided by 648 is 5 with a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 128505.0
If we subtract 3240 from 3495, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 9:
648 can be fit into 2550 3 times, resulting in a remainder of 606.
The number 3 becomes the next digit in our result. 
Result so far: 128505.3
The remainder is 606 after subtracting 1944 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

On to step 10:
The number 648 fits into 6060 9 times, leaving a remainder of 228.
The next digit of our result is 9. 
Result so far: 128505.39
Subtract 5832 from 6060 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
When dividing 2280 by 648, we get 3 with a remainder of 336.
The next digit of our result is 3. 
Result so far: 128505.393
If we take 1944 away from 2280, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 12:
648 goes into 3360 5 times with a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 128505.3935
The remainder is 120 after subtracting 3240 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 13:
1200 divided by 648 is 1 with a remainder of 552.
The number 1 becomes the next digit in our result. 
Result so far: 128505.39351
If we subtract 648 from 1200, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 14:
5520 divided by 648 is 8 with a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 128505.393518
If we subtract 5184 from 5520, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 15:
648 can be fit into 3360 5 times, resulting in a remainder of 120.
Put 5 as the next digit of the answer. 
Result so far: 128505.3935185
Subtract 3240 from 3360 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
648 goes into 1200 1 times with a remainder of 552.
Use 1 as the next digit of our solution. 
Result so far: 128505.39351851
Subtracting 648 from 1200 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The quotient of the division is 128505.39351851, and the remainder is 5.52e-07.
