547993 ÷ 77 
The aim is to understand the frequency of 77 in 547993.

Let's proceed 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
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 77

Let's proceed to step 2:
77 goes into 54 0 times with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Include the next digit (7) from the dividend after 54, then repeat: 547 / 77

On to step 3:
If we divide 547 by 77, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 539 away from 547, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 77

Let's proceed to step 4:
77 goes into 89 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
The remainder is 12 after subtracting 77 from 89.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 77

Step 5:
129 divided by 77 is 1 with a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 711.0
Subtract 77 from 129 to get 52.
Include the next digit (3) from the dividend after 52, then repeat: 523 / 77

Going ahead to step 6:
77 can be fit into 523 6 times, resulting in a remainder of 61.
Use 6 as the next digit of our solution. 
Result so far: 7116.0
If we subtract 462 from 523, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
When dividing 610 by 77, we get 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 7116.7
The remainder is 71 after subtracting 539 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 8:
When dividing 710 by 77, we get 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 7116.79
If we subtract 693 from 710, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
The number 77 fits into 170 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 7116.792
If we take 154 away from 170, 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.

Advancing to step 10:
77 goes into 160 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 7116.7922
If we take 154 away from 160, we end up 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.

Our division results in 7116.7922 with a remaining 6e-05.
