813139 ÷ 709 
The aim is to understand the frequency of 709 in 813139.

Going ahead to step 1:
709 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 709

Going ahead to step 2:
81 divided by 709 is 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (3) from the dividend, add it to 81, then carry on: 813 / 709

On to step 3:
813 divided by 709 is 1 with a remainder of 104.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 709 from 813 leaves us with 104.
Bring next digit (1) of the dividend behind the 104 and repeat the process: 1041 / 709

Going ahead to step 4:
If we divide 1041 by 709, we get 1 and a remainder of 332.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 709 from 1041 leaves us with 332.
Include the next digit (3) from the dividend after 332, then repeat: 3323 / 709

Step 5:
If we divide 3323 by 709, we get 4 and a remainder of 487.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Deduct 2836 from 3323 and we're left with 487.
Bring next digit (9) of the dividend behind the 487 and repeat the process: 4879 / 709

On to step 6:
The number 709 fits into 4879 6 times, leaving a remainder of 625.
Use 6 as the next digit of our solution. 
Result so far: 1146.0
The remainder is 625 after subtracting 4254 from 4879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 7:
The number 709 fits into 6250 8 times, leaving a remainder of 578.
Put 8 as the next digit of the answer. 
Result so far: 1146.8
If we take 5672 away from 6250, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Moving on to step 8:
5780 divided by 709 is 8 with a remainder of 108.
The next digit of our result is 8. 
Result so far: 1146.88
The remainder is 108 after subtracting 5672 from 5780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Our division results in 1146.88 with a remaining 0.108.
