61574007 ÷ 756 
The aim is to understand the frequency of 756 in 61574007.

Let's proceed to step 1:
6 divided by 756 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 756

Let's proceed to step 2:
756 can be fit into 61 0 times, resulting in a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 756

Moving on to step 3:
When dividing 615 by 756, we get 0 with a remainder of 615.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 615 to get 615.
Append the next digit (7) from the dividend to 615 and continue with: 6157 / 756

Advancing to step 4:
756 goes into 6157 8 times with a remainder of 109.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6048 from 6157 to get 109.
Bring next digit (4) of the dividend behind the 109 and repeat the process: 1094 / 756

Moving on to step 5:
756 goes into 1094 1 times with a remainder of 338.
Write down 1 as next digit of the result. 
Result so far: 81.0
Subtract 756 from 1094 to get 338.
Include the next digit (0) from the dividend after 338, then repeat: 3380 / 756

On to step 6:
If we divide 3380 by 756, we get 4 and a remainder of 356.
Put 4 as the next digit of the answer. 
Result so far: 814.0
If we take 3024 away from 3380, we end up with 356.
Fetch the next digit (0) from the dividend, attach it to 356 and continue: 3560 / 756

On to step 7:
The number 756 fits into 3560 4 times, leaving a remainder of 536.
The next digit of our result is 4. 
Result so far: 8144.0
Deduct 3024 from 3560 and we're left with 536.
Include the next digit (7) from the dividend after 536, then repeat: 5367 / 756

Going ahead to step 8:
756 goes into 5367 7 times with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 81447.0
Subtracting 5292 from 5367 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
756 goes into 750 0 times with a remainder of 750.
Record the quotient 0 as the next digit in the result. 
Result so far: 81447.0
Deduct 0 from 750 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 10:
If we divide 7500 by 756, we get 9 and a remainder of 696.
The number 9 becomes the next digit in our result. 
Result so far: 81447.09
If we take 6804 away from 7500, we end up with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 11:
When dividing 6960 by 756, we get 9 with a remainder of 156.
The number 9 becomes the next digit in our result. 
Result so far: 81447.099
Deduct 6804 from 6960 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

After the division, we end up with 81447.099 and a remainder of 0.0156.
