Let's divide 77678229 by 830
The aim is to understand the frequency of 830 in 77678229.

Advancing to step 1:
830 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 830

Going ahead to step 2:
When dividing 77 by 830, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 830

On to step 3:
When dividing 776 by 830, we get 0 with a remainder of 776.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 776 to get 776.
Bring next digit (7) of the dividend behind the 776 and repeat the process: 7767 / 830

Advancing to step 4:
If we divide 7767 by 830, we get 9 and a remainder of 297.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7470 from 7767 leaves us with 297.
Take the next digit (8) from the dividend and append it to 297, then repeat: 2978 / 830

On to step 5:
The number 830 fits into 2978 3 times, leaving a remainder of 488.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
The remainder is 488 after subtracting 2490 from 2978.
Bring next digit (2) of the dividend behind the 488 and repeat the process: 4882 / 830

Advancing to step 6:
830 goes into 4882 5 times with a remainder of 732.
Write down 5 as next digit of the result. 
Result so far: 935.0
Subtracting 4150 from 4882 leaves us with 732.
Grab the next digit (2) from the dividend, add it to 732, then carry on: 7322 / 830

On to step 7:
The number 830 fits into 7322 8 times, leaving a remainder of 682.
Write down 8 as next digit of the result. 
Result so far: 9358.0
If we subtract 6640 from 7322, we get 682.
Bring next digit (9) of the dividend behind the 682 and repeat the process: 6829 / 830

On to step 8:
830 goes into 6829 8 times with a remainder of 189.
The number 8 becomes the next digit in our result. 
Result so far: 93588.0
If we take 6640 away from 6829, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 9:
If we divide 1890 by 830, we get 2 and a remainder of 230.
The next digit of our result is 2. 
Result so far: 93588.2
If we subtract 1660 from 1890, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 10:
When dividing 2300 by 830, we get 2 with a remainder of 640.
The next digit of our result is 2. 
Result so far: 93588.22
Subtracting 1660 from 2300 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Our division results in 93588.22 with a remaining 0.64.
