We divide 76642628 by 312
The aim is to understand the frequency of 312 in 76642628.

Let's proceed to step 1:
312 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 312

On to step 2:
When dividing 76 by 312, we get 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 312

Moving on to step 3:
If we divide 766 by 312, we get 2 and a remainder of 142.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 624 from 766 to get 142.
Include the next digit (4) from the dividend after 142, then repeat: 1424 / 312

Advancing to step 4:
The number 312 fits into 1424 4 times, leaving a remainder of 176.
The next digit of our result is 4. 
Result so far: 24.0
If we take 1248 away from 1424, we end up with 176.
Take the next digit (2) from the dividend and append it to 176, then repeat: 1762 / 312

Advancing to step 5:
312 can be fit into 1762 5 times, resulting in a remainder of 202.
Use 5 as the next digit of our solution. 
Result so far: 245.0
Subtract 1560 from 1762 to get 202.
Grab the next digit (6) from the dividend, add it to 202, then carry on: 2026 / 312

Moving on to step 6:
2026 divided by 312 is 6 with a remainder of 154.
The number 6 becomes the next digit in our result. 
Result so far: 2456.0
If we subtract 1872 from 2026, we get 154.
Bring next digit (2) of the dividend behind the 154 and repeat the process: 1542 / 312

Advancing to step 7:
If we divide 1542 by 312, we get 4 and a remainder of 294.
Write down 4 as next digit of the result. 
Result so far: 24564.0
If we take 1248 away from 1542, we end up with 294.
Append the next digit (8) from the dividend to 294 and continue with: 2948 / 312

Step 8:
The number 312 fits into 2948 9 times, leaving a remainder of 140.
The next digit of our result is 9. 
Result so far: 245649.0
Deduct 2808 from 2948 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 9:
312 goes into 1400 4 times with a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 245649.4
Subtract 1248 from 1400 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 10:
312 can be fit into 1520 4 times, resulting in a remainder of 272.
Write down 4 as next digit of the result. 
Result so far: 245649.44
The remainder is 272 after subtracting 1248 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

After the division, we end up with 245649.44 and a remainder of 0.272.
