We're dividing 81945600 by 756 
The aim is to understand the frequency of 756 in 81945600.

Let's proceed to step 1:
When dividing 8 by 756, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 756

On to step 2:
756 goes into 81 0 times with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 756

Moving on to step 3:
819 divided by 756 is 1 with a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 756 from 819 and we're left with 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 756

Advancing to step 4:
756 goes into 634 0 times with a remainder of 634.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 634 leaves us with 634.
Take the next digit (5) from the dividend and append it to 634, then repeat: 6345 / 756

Advancing to step 5:
756 goes into 6345 8 times with a remainder of 297.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Deduct 6048 from 6345 and we're left with 297.
Fetch the next digit (6) from the dividend, attach it to 297 and continue: 2976 / 756

Step 6:
When dividing 2976 by 756, we get 3 with a remainder of 708.
The number 3 becomes the next digit in our result. 
Result so far: 1083.0
Subtract 2268 from 2976 to get 708.
Take the next digit (0) from the dividend and append it to 708, then repeat: 7080 / 756

Let's proceed to step 7:
When dividing 7080 by 756, we get 9 with a remainder of 276.
The number 9 becomes the next digit in our result. 
Result so far: 10839.0
Subtracting 6804 from 7080 leaves us with 276.
Take the next digit (0) from the dividend and append it to 276, then repeat: 2760 / 756

Let's proceed to step 8:
The number 756 fits into 2760 3 times, leaving a remainder of 492.
Use 3 as the next digit of our solution. 
Result so far: 108393.0
Subtracting 2268 from 2760 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 9:
756 can be fit into 4920 6 times, resulting in a remainder of 384.
The next digit of our result is 6. 
Result so far: 108393.6
The remainder is 384 after subtracting 4536 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 10:
If we divide 3840 by 756, we get 5 and a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 108393.65
The remainder is 60 after subtracting 3780 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
756 can be fit into 600 0 times, resulting in a remainder of 600.
The next digit of our result is 0. 
Result so far: 108393.65
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 12:
The number 756 fits into 6000 7 times, leaving a remainder of 708.
The number 7 becomes the next digit in our result. 
Result so far: 108393.6507
The remainder is 708 after subtracting 5292 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Moving on to step 13:
The number 756 fits into 7080 9 times, leaving a remainder of 276.
Write down 9 as next digit of the result. 
Result so far: 108393.65079
If we subtract 6804 from 7080, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 14:
756 can be fit into 2760 3 times, resulting in a remainder of 492.
Write down 3 as next digit of the result. 
Result so far: 108393.650793
Subtracting 2268 from 2760 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 15:
756 goes into 4920 6 times with a remainder of 384.
The next digit of our result is 6. 
Result so far: 108393.6507936
Subtract 4536 from 4920 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 16:
756 can be fit into 3840 5 times, resulting in a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 108393.65079365
The remainder is 60 after subtracting 3780 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 108393.65079365 with a remainder of 6e-08.
