312243 divided by 76 
The aim is to understand the frequency of 76 in 312243.

Let's proceed to step 1:
When dividing 3 by 76, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 76

Step 2:
When dividing 31 by 76, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 76

Moving on to step 3:
The number 76 fits into 312 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 304 from 312 leaves us with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 76

Step 4:
When dividing 82 by 76, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we take 76 away from 82, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 76

Advancing to step 5:
64 divided by 76 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 410.0
If we take 0 away from 64, we end up with 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 76

Step 6:
76 goes into 643 8 times with a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 4108.0
If we subtract 608 from 643, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
350 divided by 76 is 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 4108.4
If we take 304 away from 350, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
76 can be fit into 460 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 4108.46
If we subtract 456 from 460, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
76 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4108.46
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
The number 76 fits into 400 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 4108.4605
Subtracting 380 from 400 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 76 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 4108.46052
Deduct 152 from 200 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
76 goes into 480 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 4108.460526
Subtracting 456 from 480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
240 divided by 76 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 4108.4605263
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
If we divide 120 by 76, we get 1 and a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 4108.46052631
Subtract 76 from 120 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 4108.46052631 with a remainder of 4.4e-08.
