We divide 8923859 by 312
The aim is to understand the frequency of 312 in 8923859.

Going ahead to step 1:
312 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 312

Going ahead to step 2:
The number 312 fits into 89 0 times, leaving a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Fetch the next digit (2) from the dividend, attach it to 89 and continue: 892 / 312

On to step 3:
312 can be fit into 892 2 times, resulting in a remainder of 268.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 624 from 892, we get 268.
Fetch the next digit (3) from the dividend, attach it to 268 and continue: 2683 / 312

Advancing to step 4:
The number 312 fits into 2683 8 times, leaving a remainder of 187.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 2496 away from 2683, we end up with 187.
Grab the next digit (8) from the dividend, add it to 187, then carry on: 1878 / 312

Advancing to step 5:
312 goes into 1878 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 286.0
Subtract 1872 from 1878 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 312

Moving on to step 6:
When dividing 65 by 312, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 2860.0
If we take 0 away from 65, we end up with 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 312

Moving on to step 7:
312 can be fit into 659 2 times, resulting in a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 28602.0
If we take 624 away from 659, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
The number 312 fits into 350 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 28602.1
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
312 can be fit into 380 1 times, resulting in a remainder of 68.
Put 1 as the next digit of the answer. 
Result so far: 28602.11
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 28602.11 and a remainder of 0.068.
