We're dividing 76663406 by 310 
The aim is to understand the frequency of 310 in 76663406.

Step 1:
If we divide 7 by 310, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 310

Let's proceed to step 2:
76 divided by 310 is 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Fetch the next digit (6) from the dividend, attach it to 76 and continue: 766 / 310

On to step 3:
The number 310 fits into 766 2 times, leaving a remainder of 146.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 620 from 766 leaves us with 146.
Include the next digit (6) from the dividend after 146, then repeat: 1466 / 310

Moving on to step 4:
310 can be fit into 1466 4 times, resulting in a remainder of 226.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 226 after subtracting 1240 from 1466.
Append the next digit (3) from the dividend to 226 and continue with: 2263 / 310

Advancing to step 5:
2263 divided by 310 is 7 with a remainder of 93.
The next digit of our result is 7. 
Result so far: 247.0
If we take 2170 away from 2263, we end up with 93.
Include the next digit (4) from the dividend after 93, then repeat: 934 / 310

On to step 6:
The number 310 fits into 934 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 2473.0
If we subtract 930 from 934, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 310

Going ahead to step 7:
If we divide 40 by 310, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 24730.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 310

Going ahead to step 8:
If we divide 406 by 310, we get 1 and a remainder of 96.
The next digit of our result is 1. 
Result so far: 247301.0
Deduct 310 from 406 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
310 can be fit into 960 3 times, resulting in a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 247301.3
Subtracting 930 from 960 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 310 is 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 247301.3
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
310 can be fit into 3000 9 times, resulting in a remainder of 210.
The next digit of our result is 9. 
Result so far: 247301.309
If we take 2790 away from 3000, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 12:
If we divide 2100 by 310, we get 6 and a remainder of 240.
Use 6 as the next digit of our solution. 
Result so far: 247301.3096
If we subtract 1860 from 2100, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
The number 310 fits into 2400 7 times, leaving a remainder of 230.
Put 7 as the next digit of the answer. 
Result so far: 247301.30967
The remainder is 230 after subtracting 2170 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 14:
The number 310 fits into 2300 7 times, leaving a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 247301.309677
Deduct 2170 from 2300 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

In conclusion, the division gives 247301.309677 with a balance of 1.3e-05.
