We look at the division of 82820056 by 648 
The aim is to understand the frequency of 648 in 82820056.

On to step 1:
648 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 648

Let's proceed to step 2:
82 divided by 648 is 0 with a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Bring next digit (8) of the dividend behind the 82 and repeat the process: 828 / 648

Going ahead to step 3:
648 can be fit into 828 1 times, resulting in a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 648 away from 828, we end up with 180.
Include the next digit (2) from the dividend after 180, then repeat: 1802 / 648

Advancing to step 4:
1802 divided by 648 is 2 with a remainder of 506.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 1296 from 1802 leaves us with 506.
Include the next digit (0) from the dividend after 506, then repeat: 5060 / 648

Step 5:
If we divide 5060 by 648, we get 7 and a remainder of 524.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Subtracting 4536 from 5060 leaves us with 524.
Fetch the next digit (0) from the dividend, attach it to 524 and continue: 5240 / 648

Moving on to step 6:
648 goes into 5240 8 times with a remainder of 56.
The next digit of our result is 8. 
Result so far: 1278.0
The remainder is 56 after subtracting 5184 from 5240.
Bring next digit (5) of the dividend behind the 56 and repeat the process: 565 / 648

Advancing to step 7:
When dividing 565 by 648, we get 0 with a remainder of 565.
Put 0 as the next digit of the answer. 
Result so far: 12780.0
The remainder is 565 after subtracting 0 from 565.
Include the next digit (6) from the dividend after 565, then repeat: 5656 / 648

On to step 8:
The number 648 fits into 5656 8 times, leaving a remainder of 472.
Record the quotient 8 as the next digit in the result. 
Result so far: 127808.0
If we subtract 5184 from 5656, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 9:
648 can be fit into 4720 7 times, resulting in a remainder of 184.
Write down 7 as next digit of the result. 
Result so far: 127808.7
Deduct 4536 from 4720 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 10:
648 can be fit into 1840 2 times, resulting in a remainder of 544.
Use 2 as the next digit of our solution. 
Result so far: 127808.72
If we take 1296 away from 1840, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 11:
648 can be fit into 5440 8 times, resulting in a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 127808.728
If we subtract 5184 from 5440, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 12:
If we divide 2560 by 648, we get 3 and a remainder of 616.
The next digit of our result is 3. 
Result so far: 127808.7283
Deduct 1944 from 2560 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 13:
648 goes into 6160 9 times with a remainder of 328.
The next digit of our result is 9. 
Result so far: 127808.72839
Subtract 5832 from 6160 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 14:
648 goes into 3280 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 127808.728395
Deduct 3240 from 3280 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
If we divide 400 by 648, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 127808.728395
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 16:
4000 divided by 648 is 6 with a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 127808.72839506
Subtract 3888 from 4000 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The quotient of the division is 127808.72839506, and the remainder is 1.12e-07.
