We divide 843313 by 77
The aim is to understand the frequency of 77 in 843313.

On to step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 77

On to step 2:
77 can be fit into 84 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 77 from 84, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 77

Going ahead to step 3:
73 divided by 77 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 73, we get 73.
Take the next digit (3) from the dividend and append it to 73, then repeat: 733 / 77

Let's proceed to step 4:
733 divided by 77 is 9 with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 109.0
If we subtract 693 from 733, we get 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 77

Let's proceed to step 5:
401 divided by 77 is 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 1095.0
Subtract 385 from 401 to get 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 77

Moving on to step 6:
77 can be fit into 163 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 10952.0
If we take 154 away from 163, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
When dividing 90 by 77, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 10952.1
If we subtract 77 from 90, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
The number 77 fits into 130 1 times, leaving a remainder of 53.
The next digit of our result is 1. 
Result so far: 10952.11
If we take 77 away from 130, 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.

In conclusion, the division gives 10952.11 with a balance of 0.053.
