48258409 ÷ 279 
We want to divide 48258409 by 279.

On to step 1:
279 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 279

Step 2:
48 divided by 279 is 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 279

Step 3:
The number 279 fits into 482 1 times, leaving a remainder of 203.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 203 after subtracting 279 from 482.
Include the next digit (5) from the dividend after 203, then repeat: 2035 / 279

On to step 4:
279 can be fit into 2035 7 times, resulting in a remainder of 82.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 82 after subtracting 1953 from 2035.
Append the next digit (8) from the dividend to 82 and continue with: 828 / 279

Going ahead to step 5:
279 can be fit into 828 2 times, resulting in a remainder of 270.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Subtract 558 from 828 to get 270.
Include the next digit (4) from the dividend after 270, then repeat: 2704 / 279

Let's proceed to step 6:
When dividing 2704 by 279, we get 9 with a remainder of 193.
Write down 9 as next digit of the result. 
Result so far: 1729.0
Subtract 2511 from 2704 to get 193.
Take the next digit (0) from the dividend and append it to 193, then repeat: 1930 / 279

On to step 7:
When dividing 1930 by 279, we get 6 with a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 17296.0
If we subtract 1674 from 1930, we get 256.
Fetch the next digit (9) from the dividend, attach it to 256 and continue: 2569 / 279

Step 8:
If we divide 2569 by 279, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 172969.0
Subtracting 2511 from 2569 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
If we divide 580 by 279, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 172969.2
Deduct 558 from 580 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
When dividing 220 by 279, we get 0 with a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 172969.2
If we take 0 away from 220, we end up 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.

Step 11:
279 can be fit into 2200 7 times, resulting in a remainder of 247.
Write down 7 as next digit of the result. 
Result so far: 172969.207
If we take 1953 away from 2200, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 12:
279 goes into 2470 8 times with a remainder of 238.
Write down 8 as next digit of the result. 
Result so far: 172969.2078
If we take 2232 away from 2470, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 13:
The number 279 fits into 2380 8 times, leaving a remainder of 148.
The next digit of our result is 8. 
Result so far: 172969.20788
If we subtract 2232 from 2380, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Our division results in 172969.20788 with a remaining 0.000148.
