Let's divide 312783 by 68
The aim is to understand the frequency of 68 in 312783.

Step 1:
If we divide 3 by 68, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 68

Moving on to step 2:
The number 68 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 68

Advancing to step 3:
The number 68 fits into 312 4 times, leaving a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 272 away from 312, we end up with 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 68

Going ahead to step 4:
68 goes into 407 5 times with a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we take 340 away from 407, we end up with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 68

Going ahead to step 5:
678 divided by 68 is 9 with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
If we take 612 away from 678, we end up with 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 68

On to step 6:
When dividing 663 by 68, we get 9 with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 4599.0
If we take 612 away from 663, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
If we divide 510 by 68, we get 7 and a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 4599.7
Subtracting 476 from 510 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
When dividing 340 by 68, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4599.75
Subtracting 340 from 340 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 68 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4599.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 68, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4599.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4599.75 with a remaining 0.0.
