We're dividing 54868591 by 312 
The aim is to understand the frequency of 312 in 54868591.

Moving on to step 1:
5 divided by 312 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 312

Advancing to step 2:
312 can be fit into 54 0 times, resulting in a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 312

On to step 3:
The number 312 fits into 548 1 times, leaving a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 312 from 548, we get 236.
Take the next digit (6) from the dividend and append it to 236, then repeat: 2366 / 312

On to step 4:
312 can be fit into 2366 7 times, resulting in a remainder of 182.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 2184 from 2366, we get 182.
Include the next digit (8) from the dividend after 182, then repeat: 1828 / 312

Advancing to step 5:
When dividing 1828 by 312, we get 5 with a remainder of 268.
Use 5 as the next digit of our solution. 
Result so far: 175.0
Subtracting 1560 from 1828 leaves us with 268.
Append the next digit (5) from the dividend to 268 and continue with: 2685 / 312

Advancing to step 6:
2685 divided by 312 is 8 with a remainder of 189.
Write down 8 as next digit of the result. 
Result so far: 1758.0
If we take 2496 away from 2685, we end up with 189.
Append the next digit (9) from the dividend to 189 and continue with: 1899 / 312

Moving on to step 7:
312 goes into 1899 6 times with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 17586.0
Subtracting 1872 from 1899 leaves us with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 312

Moving on to step 8:
When dividing 271 by 312, we get 0 with a remainder of 271.
The next digit of our result is 0. 
Result so far: 175860.0
If we subtract 0 from 271, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Going ahead to step 9:
312 goes into 2710 8 times with a remainder of 214.
The number 8 becomes the next digit in our result. 
Result so far: 175860.8
Deduct 2496 from 2710 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 10:
312 can be fit into 2140 6 times, resulting in a remainder of 268.
Record the quotient 6 as the next digit in the result. 
Result so far: 175860.86
If we take 1872 away from 2140, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 11:
The number 312 fits into 2680 8 times, leaving a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 175860.868
Deduct 2496 from 2680 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 12:
The number 312 fits into 1840 5 times, leaving a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 175860.8685
Subtracting 1560 from 1840 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 13:
312 can be fit into 2800 8 times, resulting in a remainder of 304.
Use 8 as the next digit of our solution. 
Result so far: 175860.86858
The remainder is 304 after subtracting 2496 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 14:
When dividing 3040 by 312, we get 9 with a remainder of 232.
Use 9 as the next digit of our solution. 
Result so far: 175860.868589
Subtract 2808 from 3040 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 15:
2320 divided by 312 is 7 with a remainder of 136.
Put 7 as the next digit of the answer. 
Result so far: 175860.8685897
Deduct 2184 from 2320 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 16:
312 can be fit into 1360 4 times, resulting in a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 175860.86858974
If we take 1248 away from 1360, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 175860.86858974 with a remainder of 1.12e-07.
