We divide 752324 by 77
The aim is to understand the frequency of 77 in 752324.

On to step 1:
7 divided by 77 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 77

Step 2:
When dividing 75 by 77, we get 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Append the next digit (2) from the dividend to 75 and continue with: 752 / 77

Going ahead to step 3:
If we divide 752 by 77, we get 9 and a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 59 after subtracting 693 from 752.
Bring next digit (3) of the dividend behind the 59 and repeat the process: 593 / 77

Step 4:
If we divide 593 by 77, we get 7 and a remainder of 54.
The next digit of our result is 7. 
Result so far: 97.0
Subtracting 539 from 593 leaves us with 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 77

Moving on to step 5:
77 goes into 542 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 977.0
Subtract 539 from 542 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 77

Moving on to step 6:
77 goes into 34 0 times with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 9770.0
The remainder is 34 after subtracting 0 from 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
77 can be fit into 340 4 times, resulting in a remainder of 32.
The next digit of our result is 4. 
Result so far: 9770.4
If we take 308 away from 340, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
77 can be fit into 320 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 9770.44
Subtracting 308 from 320 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 9770.44, with a leftover of 0.012.
