We're dividing 563424 by 77 
The aim is to understand the frequency of 77 in 563424.

Moving on to step 1:
When dividing 5 by 77, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 77

Moving on to step 2:
77 goes into 56 0 times with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Take the next digit (3) from the dividend and append it to 56, then repeat: 563 / 77

Step 3:
77 can be fit into 563 7 times, resulting in a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 539 away from 563, we end up with 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 77

Let's proceed to step 4:
When dividing 244 by 77, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we subtract 231 from 244, we get 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 77

Going ahead to step 5:
132 divided by 77 is 1 with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 731.0
The remainder is 55 after subtracting 77 from 132.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 77

Let's proceed to step 6:
If we divide 554 by 77, we get 7 and a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 7317.0
Subtracting 539 from 554 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
The number 77 fits into 150 1 times, leaving a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 7317.1
Subtracting 77 from 150 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 8:
730 divided by 77 is 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 7317.19
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
When dividing 370 by 77, we get 4 with a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 7317.194
Subtracting 308 from 370 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
If we divide 620 by 77, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 7317.1948
Subtract 616 from 620 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
When dividing 40 by 77, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 7317.1948
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
77 goes into 400 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 7317.194805
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
If we divide 150 by 77, we get 1 and a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 7317.1948051
Subtracting 77 from 150 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 14:
77 goes into 730 9 times with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 7317.19480519
If we take 693 away from 730, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The quotient of the division is 7317.19480519, and the remainder is 3.7e-08.
