Let's divide 742580 by 77
The aim is to understand the frequency of 77 in 742580.

On to step 1:
77 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 77

Advancing to step 2:
If we divide 74 by 77, we get 0 and a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 77

Advancing to step 3:
If we divide 742 by 77, we get 9 and a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 693 away from 742, we end up with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 77

Going ahead to step 4:
495 divided by 77 is 6 with a remainder of 33.
The next digit of our result is 6. 
Result so far: 96.0
If we subtract 462 from 495, we get 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 77

Step 5:
77 goes into 338 4 times with a remainder of 30.
The next digit of our result is 4. 
Result so far: 964.0
Subtract 308 from 338 to get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 77

Step 6:
The number 77 fits into 300 3 times, leaving a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 9643.0
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 7:
If we divide 690 by 77, we get 8 and a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 9643.8
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.

Step 8:
77 can be fit into 740 9 times, resulting in a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 9643.89
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 can be fit into 470 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 9643.896
Subtracting 462 from 470 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 77, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 9643.8961
If we take 77 away from 80, we end up 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:
If we divide 30 by 77, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9643.8961
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.

Step 12:
If we divide 300 by 77, we get 3 and a remainder of 69.
The next digit of our result is 3. 
Result so far: 9643.896103
If we take 231 away from 300, 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.

On to step 13:
690 divided by 77 is 8 with a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 9643.8961038
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.

Moving on to step 14:
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: 9643.89610389
Deduct 693 from 740 and we're left 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.

The quotient of the division is 9643.89610389, and the remainder is 4.7e-08.
