We look at the division of 753283 by 77 
The aim is to understand the frequency of 77 in 753283.

Step 1:
If we divide 7 by 77, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 77

Going ahead to step 2:
When dividing 75 by 77, we get 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Take the next digit (3) from the dividend and append it to 75, then repeat: 753 / 77

Moving on to step 3:
77 can be fit into 753 9 times, resulting in a remainder of 60.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 693 away from 753, we end up with 60.
Include the next digit (2) from the dividend after 60, then repeat: 602 / 77

Going ahead to step 4:
If we divide 602 by 77, we get 7 and a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we subtract 539 from 602, we get 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 77

Let's proceed to step 5:
If we divide 638 by 77, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 978.0
If we take 616 away from 638, we end up with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 77

Let's proceed to step 6:
If we divide 223 by 77, we get 2 and a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 9782.0
If we take 154 away from 223, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
If we divide 690 by 77, we get 8 and a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 9782.8
The remainder is 74 after subtracting 616 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
If we divide 740 by 77, we get 9 and a remainder of 47.
The next digit of our result is 9. 
Result so far: 9782.89
If we take 693 away from 740, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
77 goes into 470 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 9782.896
Subtract 462 from 470 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 77 fits into 80 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 9782.8961
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
When dividing 30 by 77, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9782.8961
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
If we divide 300 by 77, we get 3 and a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 9782.896103
If we subtract 231 from 300, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 13:
77 goes into 690 8 times with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 9782.8961038
Subtract 616 from 690 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 14:
If we divide 740 by 77, we get 9 and a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 9782.89610389
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 9782.89610389, and the remainder is 4.7e-08.
