We divide 996654 by 77
The aim is to understand the frequency of 77 in 996654.

On to step 1:
If we divide 9 by 77, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 77

Going ahead to step 2:
77 can be fit into 99 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 77 away from 99, we end up with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 77

On to step 3:
226 divided by 77 is 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 72 after subtracting 154 from 226.
Include the next digit (6) from the dividend after 72, then repeat: 726 / 77

On to step 4:
77 goes into 726 9 times with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 129.0
Deduct 693 from 726 and we're left with 33.
Fetch the next digit (5) from the dividend, attach it to 33 and continue: 335 / 77

On to step 5:
77 goes into 335 4 times with a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 1294.0
Deduct 308 from 335 and we're left with 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 77

On to step 6:
If we divide 274 by 77, we get 3 and a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 12943.0
Subtract 231 from 274 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
430 divided by 77 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 12943.5
If we take 385 away from 430, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 8:
450 divided by 77 is 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 12943.55
Subtract 385 from 450 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 12943.55 with a remainder of 0.065.
