83402509 divided by 312 
The aim is to understand the frequency of 312 in 83402509.

Going ahead to step 1:
When dividing 8 by 312, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 312

Let's proceed to step 2:
312 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 312

On to step 3:
If we divide 834 by 312, we get 2 and a remainder of 210.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 624 away from 834, we end up with 210.
Append the next digit (0) from the dividend to 210 and continue with: 2100 / 312

Let's proceed to step 4:
2100 divided by 312 is 6 with a remainder of 228.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 1872 from 2100 to get 228.
Grab the next digit (2) from the dividend, add it to 228, then carry on: 2282 / 312

Going ahead to step 5:
When dividing 2282 by 312, we get 7 with a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 267.0
If we take 2184 away from 2282, we end up with 98.
Fetch the next digit (5) from the dividend, attach it to 98 and continue: 985 / 312

Step 6:
If we divide 985 by 312, we get 3 and a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 2673.0
If we take 936 away from 985, we end up with 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 312

Going ahead to step 7:
312 can be fit into 490 1 times, resulting in a remainder of 178.
Record the quotient 1 as the next digit in the result. 
Result so far: 26731.0
Subtract 312 from 490 to get 178.
Bring next digit (9) of the dividend behind the 178 and repeat the process: 1789 / 312

Going ahead to step 8:
312 can be fit into 1789 5 times, resulting in a remainder of 229.
The number 5 becomes the next digit in our result. 
Result so far: 267315.0
The remainder is 229 after subtracting 1560 from 1789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 9:
312 can be fit into 2290 7 times, resulting in a remainder of 106.
The next digit of our result is 7. 
Result so far: 267315.7
Subtract 2184 from 2290 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
When dividing 1060 by 312, we get 3 with a remainder of 124.
Write down 3 as next digit of the result. 
Result so far: 267315.73
If we take 936 away from 1060, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 11:
If we divide 1240 by 312, we get 3 and a remainder of 304.
Record the quotient 3 as the next digit in the result. 
Result so far: 267315.733
If we take 936 away from 1240, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

In conclusion, the division gives 267315.733 with a balance of 0.0304.
