We divide 70644335 by 717
The aim is to understand the frequency of 717 in 70644335.

On to step 1:
When dividing 7 by 717, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 717

Going ahead to step 2:
717 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Bring next digit (6) of the dividend behind the 70 and repeat the process: 706 / 717

Let's proceed to step 3:
If we divide 706 by 717, we get 0 and a remainder of 706.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 706, we end up with 706.
Bring next digit (4) of the dividend behind the 706 and repeat the process: 7064 / 717

Going ahead to step 4:
If we divide 7064 by 717, we get 9 and a remainder of 611.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 6453 from 7064 leaves us with 611.
Include the next digit (4) from the dividend after 611, then repeat: 6114 / 717

On to step 5:
The number 717 fits into 6114 8 times, leaving a remainder of 378.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we subtract 5736 from 6114, we get 378.
Bring next digit (3) of the dividend behind the 378 and repeat the process: 3783 / 717

On to step 6:
717 goes into 3783 5 times with a remainder of 198.
The number 5 becomes the next digit in our result. 
Result so far: 985.0
If we subtract 3585 from 3783, we get 198.
Bring next digit (3) of the dividend behind the 198 and repeat the process: 1983 / 717

Moving on to step 7:
717 can be fit into 1983 2 times, resulting in a remainder of 549.
Record the quotient 2 as the next digit in the result. 
Result so far: 9852.0
If we subtract 1434 from 1983, we get 549.
Bring next digit (5) of the dividend behind the 549 and repeat the process: 5495 / 717

Going ahead to step 8:
If we divide 5495 by 717, we get 7 and a remainder of 476.
Record the quotient 7 as the next digit in the result. 
Result so far: 98527.0
If we take 5019 away from 5495, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 9:
If we divide 4760 by 717, we get 6 and a remainder of 458.
Use 6 as the next digit of our solution. 
Result so far: 98527.6
Subtract 4302 from 4760 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 10:
When dividing 4580 by 717, we get 6 with a remainder of 278.
Use 6 as the next digit of our solution. 
Result so far: 98527.66
The remainder is 278 after subtracting 4302 from 4580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The quotient of the division is 98527.66, and the remainder is 0.278.
