We divide 866578 by 77
The aim is to understand the frequency of 77 in 866578.

On to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 77

Let's proceed to step 2:
77 can be fit into 86 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 77 from 86 to get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 77

Step 3:
If we divide 96 by 77, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 77 away from 96, we end up with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 77

On to step 4:
The number 77 fits into 195 2 times, leaving a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we subtract 154 from 195, we get 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 77

Going ahead to step 5:
77 goes into 417 5 times with a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 1125.0
Subtract 385 from 417 to get 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 77

Step 6:
77 goes into 328 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 11254.0
Subtract 308 from 328 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
77 can be fit into 200 2 times, resulting in a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 11254.2
Subtracting 154 from 200 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
If we divide 460 by 77, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 11254.25
Subtract 385 from 460 to get 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:
When dividing 750 by 77, we get 9 with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 11254.259
The remainder is 57 after subtracting 693 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 10:
The number 77 fits into 570 7 times, leaving a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 11254.2597
The remainder is 31 after subtracting 539 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 11:
77 can be fit into 310 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 11254.25974
If we subtract 308 from 310, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
If we divide 20 by 77, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 11254.25974
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
200 divided by 77 is 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 11254.2597402
Deduct 154 from 200 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 14:
460 divided by 77 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 11254.25974025
If we take 385 away from 460, we end up 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.

The quotient of the division is 11254.25974025, and the remainder is 7.5e-08.
