We divide 572742 by 77
The aim is to understand the frequency of 77 in 572742.

Advancing to step 1:
5 divided by 77 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 77

Advancing to step 2:
When dividing 57 by 77, we get 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 77

Advancing to step 3:
572 divided by 77 is 7 with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 33 after subtracting 539 from 572.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 77

Going ahead to step 4:
When dividing 337 by 77, we get 4 with a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtracting 308 from 337 leaves us with 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 77

Step 5:
The number 77 fits into 294 3 times, leaving a remainder of 63.
The next digit of our result is 3. 
Result so far: 743.0
Deduct 231 from 294 and we're left with 63.
Fetch the next digit (2) from the dividend, attach it to 63 and continue: 632 / 77

Going ahead to step 6:
77 can be fit into 632 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 7438.0
If we take 616 away from 632, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
160 divided by 77 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 7438.2
Deduct 154 from 160 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
60 divided by 77 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 7438.2
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 77, we get 7 with a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 7438.207
The remainder is 61 after subtracting 539 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 10:
77 can be fit into 610 7 times, resulting in a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 7438.2077
Subtract 539 from 610 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 7438.2077 and a remainder of 0.00071.
