28552465 ÷ 231 
We want to figure out the number of times 28552465 can be divided by 231.

Step 1:
2 divided by 231 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 231

Moving on to step 2:
231 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 231

Step 3:
When dividing 285 by 231, we get 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 231 from 285 and we're left with 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 231

Moving on to step 4:
545 divided by 231 is 2 with a remainder of 83.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 462 from 545, we get 83.
Include the next digit (2) from the dividend after 83, then repeat: 832 / 231

Step 5:
When dividing 832 by 231, we get 3 with a remainder of 139.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Deduct 693 from 832 and we're left with 139.
Include the next digit (4) from the dividend after 139, then repeat: 1394 / 231

Moving on to step 6:
The number 231 fits into 1394 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 1236.0
If we take 1386 away from 1394, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 231

Going ahead to step 7:
When dividing 86 by 231, we get 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 12360.0
Subtract 0 from 86 to get 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 231

Let's proceed to step 8:
If we divide 865 by 231, we get 3 and a remainder of 172.
Record the quotient 3 as the next digit in the result. 
Result so far: 123603.0
Subtracting 693 from 865 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 9:
The number 231 fits into 1720 7 times, leaving a remainder of 103.
Write down 7 as next digit of the result. 
Result so far: 123603.7
The remainder is 103 after subtracting 1617 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 10:
The number 231 fits into 1030 4 times, leaving a remainder of 106.
Use 4 as the next digit of our solution. 
Result so far: 123603.74
Deduct 924 from 1030 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 11:
If we divide 1060 by 231, we get 4 and a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 123603.744
Deduct 924 from 1060 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.

The quotient of the division is 123603.744, and the remainder is 0.0136.
