603733 divided by 77 
The aim is to understand the frequency of 77 in 603733.

Going ahead to step 1:
77 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 77

Going ahead to step 2:
If we divide 60 by 77, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 77

Let's proceed to step 3:
77 can be fit into 603 7 times, resulting in a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 539 from 603 and we're left with 64.
Grab the next digit (7) from the dividend, add it to 64, then carry on: 647 / 77

Let's proceed to step 4:
77 goes into 647 8 times with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
The remainder is 31 after subtracting 616 from 647.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 77

On to step 5:
If we divide 313 by 77, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 784.0
Subtract 308 from 313 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 77

Moving on to step 6:
The number 77 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 7840.0
If we take 0 away from 53, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
77 can be fit into 530 6 times, resulting in a remainder of 68.
The next digit of our result is 6. 
Result so far: 7840.6
Deduct 462 from 530 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
77 goes into 680 8 times with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 7840.68
Deduct 616 from 680 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
640 divided by 77 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 7840.688
If we subtract 616 from 640, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 7840.688 with a remainder of 0.0024.
