90539734 ÷ 756 
The aim is to understand the frequency of 756 in 90539734.

Step 1:
If we divide 9 by 756, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 756

Going ahead to step 2:
90 divided by 756 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 756

On to step 3:
756 can be fit into 905 1 times, resulting in a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 756 from 905 leaves us with 149.
Grab the next digit (3) from the dividend, add it to 149, then carry on: 1493 / 756

Let's proceed to step 4:
756 goes into 1493 1 times with a remainder of 737.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 756 from 1493 leaves us with 737.
Fetch the next digit (9) from the dividend, attach it to 737 and continue: 7379 / 756

Let's proceed to step 5:
756 goes into 7379 9 times with a remainder of 575.
Put 9 as the next digit of the answer. 
Result so far: 119.0
The remainder is 575 after subtracting 6804 from 7379.
Grab the next digit (7) from the dividend, add it to 575, then carry on: 5757 / 756

Step 6:
If we divide 5757 by 756, we get 7 and a remainder of 465.
Record the quotient 7 as the next digit in the result. 
Result so far: 1197.0
Subtracting 5292 from 5757 leaves us with 465.
Fetch the next digit (3) from the dividend, attach it to 465 and continue: 4653 / 756

Moving on to step 7:
756 goes into 4653 6 times with a remainder of 117.
Write down 6 as next digit of the result. 
Result so far: 11976.0
The remainder is 117 after subtracting 4536 from 4653.
Append the next digit (4) from the dividend to 117 and continue with: 1174 / 756

Going ahead to step 8:
If we divide 1174 by 756, we get 1 and a remainder of 418.
Write down 1 as next digit of the result. 
Result so far: 119761.0
Subtract 756 from 1174 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 9:
If we divide 4180 by 756, we get 5 and a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 119761.5
Deduct 3780 from 4180 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 10:
4000 divided by 756 is 5 with a remainder of 220.
Use 5 as the next digit of our solution. 
Result so far: 119761.55
If we subtract 3780 from 4000, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 119761.55 and a remainder of 0.22.
