70479777 ÷ 817 
The aim is to understand the frequency of 817 in 70479777.

Moving on to step 1:
817 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
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 / 817

Let's proceed to step 2:
817 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 817

Going ahead to step 3:
If we divide 704 by 817, we get 0 and a remainder of 704.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 704, we get 704.
Append the next digit (7) from the dividend to 704 and continue with: 7047 / 817

Advancing to step 4:
When dividing 7047 by 817, we get 8 with a remainder of 511.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 511 after subtracting 6536 from 7047.
Append the next digit (9) from the dividend to 511 and continue with: 5119 / 817

Step 5:
817 can be fit into 5119 6 times, resulting in a remainder of 217.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
The remainder is 217 after subtracting 4902 from 5119.
Append the next digit (7) from the dividend to 217 and continue with: 2177 / 817

On to step 6:
The number 817 fits into 2177 2 times, leaving a remainder of 543.
Put 2 as the next digit of the answer. 
Result so far: 862.0
If we subtract 1634 from 2177, we get 543.
Bring next digit (7) of the dividend behind the 543 and repeat the process: 5437 / 817

Advancing to step 7:
When dividing 5437 by 817, we get 6 with a remainder of 535.
Use 6 as the next digit of our solution. 
Result so far: 8626.0
If we subtract 4902 from 5437, we get 535.
Append the next digit (7) from the dividend to 535 and continue with: 5357 / 817

Advancing to step 8:
5357 divided by 817 is 6 with a remainder of 455.
Use 6 as the next digit of our solution. 
Result so far: 86266.0
If we take 4902 away from 5357, we end up with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Step 9:
When dividing 4550 by 817, we get 5 with a remainder of 465.
The number 5 becomes the next digit in our result. 
Result so far: 86266.5
Deduct 4085 from 4550 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 10:
If we divide 4650 by 817, we get 5 and a remainder of 565.
Write down 5 as next digit of the result. 
Result so far: 86266.55
If we subtract 4085 from 4650, we get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Our division results in 86266.55 with a remaining 0.565.
