28439917 ÷ 230 
We want to figure out the number of times 28439917 can be divided by 230.

Let's proceed to step 1:
230 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 230

Let's proceed to step 2:
28 divided by 230 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 230

Advancing to step 3:
The number 230 fits into 284 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 230 from 284 leaves us with 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 230

Advancing to step 4:
When dividing 543 by 230, we get 2 with a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 460 from 543, we get 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 230

Advancing to step 5:
When dividing 839 by 230, we get 3 with a remainder of 149.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtracting 690 from 839 leaves us with 149.
Append the next digit (9) from the dividend to 149 and continue with: 1499 / 230

Going ahead to step 6:
If we divide 1499 by 230, we get 6 and a remainder of 119.
Write down 6 as next digit of the result. 
Result so far: 1236.0
If we take 1380 away from 1499, we end up with 119.
Include the next digit (1) from the dividend after 119, then repeat: 1191 / 230

Let's proceed to step 7:
If we divide 1191 by 230, we get 5 and a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 12365.0
Subtracting 1150 from 1191 leaves us with 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 230

On to step 8:
417 divided by 230 is 1 with a remainder of 187.
Put 1 as the next digit of the answer. 
Result so far: 123651.0
Deduct 230 from 417 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 9:
230 goes into 1870 8 times with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 123651.8
The remainder is 30 after subtracting 1840 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
If we divide 300 by 230, we get 1 and a remainder of 70.
The next digit of our result is 1. 
Result so far: 123651.81
If we subtract 230 from 300, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
When dividing 700 by 230, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 123651.813
If we take 690 away from 700, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
230 goes into 100 0 times with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 123651.813
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
230 can be fit into 1000 4 times, resulting in a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 123651.81304
Subtracting 920 from 1000 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
If we divide 800 by 230, we get 3 and a remainder of 110.
The number 3 becomes the next digit in our result. 
Result so far: 123651.813043
If we subtract 690 from 800, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 15:
If we divide 1100 by 230, we get 4 and a remainder of 180.
The number 4 becomes the next digit in our result. 
Result so far: 123651.8130434
Subtracting 920 from 1100 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 16:
230 goes into 1800 7 times with a remainder of 190.
Write down 7 as next digit of the result. 
Result so far: 123651.81304347
Subtracting 1610 from 1800 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Our division results in 123651.81304347 with a remaining 1.9e-07.
