We divide 2846140 by 231
The aim is to understand the frequency of 231 in 2846140.

Step 1:
The number 231 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 231

Going ahead to step 2:
If we divide 28 by 231, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 231

Let's proceed to step 3:
231 can be fit into 284 1 times, resulting in a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 231 away from 284, we end up with 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 231

Moving on to step 4:
536 divided by 231 is 2 with a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 74 after subtracting 462 from 536.
Fetch the next digit (1) from the dividend, attach it to 74 and continue: 741 / 231

Moving on to step 5:
If we divide 741 by 231, we get 3 and a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 123.0
If we take 693 away from 741, we end up with 48.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 231

On to step 6:
231 can be fit into 484 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 1232.0
The remainder is 22 after subtracting 462 from 484.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 231

Advancing to step 7:
220 divided by 231 is 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 12320.0
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 8:
231 can be fit into 2200 9 times, resulting in a remainder of 121.
Use 9 as the next digit of our solution. 
Result so far: 12320.9
If we take 2079 away from 2200, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 9:
The number 231 fits into 1210 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 12320.95
Subtract 1155 from 1210 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
The number 231 fits into 550 2 times, leaving a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 12320.952
The remainder is 88 after subtracting 462 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 11:
When dividing 880 by 231, we get 3 with a remainder of 187.
Record the quotient 3 as the next digit in the result. 
Result so far: 12320.9523
If we subtract 693 from 880, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 12:
231 can be fit into 1870 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 12320.95238
Subtract 1848 from 1870 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
220 divided by 231 is 0 with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 12320.95238
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 14:
When dividing 2200 by 231, we get 9 with a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 12320.9523809
If we take 2079 away from 2200, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 15:
The number 231 fits into 1210 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 12320.95238095
The remainder is 55 after subtracting 1155 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 12320.95238095 with a remaining 5.5e-08.
