614836 divided by 77 
The aim is to understand the frequency of 77 in 614836.

Step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 77

Going ahead to step 2:
The number 77 fits into 61 0 times, leaving a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Take the next digit (4) from the dividend and append it to 61, then repeat: 614 / 77

Advancing to step 3:
614 divided by 77 is 7 with a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 539 from 614 leaves us with 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 77

Advancing to step 4:
758 divided by 77 is 9 with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
If we take 693 away from 758, we end up with 65.
Append the next digit (3) from the dividend to 65 and continue with: 653 / 77

Moving on to step 5:
The number 77 fits into 653 8 times, leaving a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 798.0
Deduct 616 from 653 and we're left with 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 77

Moving on to step 6:
The number 77 fits into 376 4 times, leaving a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 7984.0
Subtract 308 from 376 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
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: 7984.8
Subtracting 616 from 680 leaves us 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.

Going ahead to step 8:
The number 77 fits into 640 8 times, leaving a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 7984.88
The remainder is 24 after subtracting 616 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 7984.88 and a remainder of 0.024.
