We're dividing 48938415 by 309 
Let's see how many times 309 fits into 48938415.

On to step 1:
309 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 309

Advancing to step 2:
The number 309 fits into 48 0 times, leaving a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 309

Moving on to step 3:
If we divide 489 by 309, we get 1 and a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 309 from 489 to get 180.
Append the next digit (3) from the dividend to 180 and continue with: 1803 / 309

Let's proceed to step 4:
The number 309 fits into 1803 5 times, leaving a remainder of 258.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 1545 from 1803 and we're left with 258.
Bring next digit (8) of the dividend behind the 258 and repeat the process: 2588 / 309

Let's proceed to step 5:
When dividing 2588 by 309, we get 8 with a remainder of 116.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
Subtract 2472 from 2588 to get 116.
Append the next digit (4) from the dividend to 116 and continue with: 1164 / 309

Step 6:
If we divide 1164 by 309, we get 3 and a remainder of 237.
The next digit of our result is 3. 
Result so far: 1583.0
Subtracting 927 from 1164 leaves us with 237.
Bring next digit (1) of the dividend behind the 237 and repeat the process: 2371 / 309

Going ahead to step 7:
The number 309 fits into 2371 7 times, leaving a remainder of 208.
Write down 7 as next digit of the result. 
Result so far: 15837.0
Subtract 2163 from 2371 to get 208.
Take the next digit (5) from the dividend and append it to 208, then repeat: 2085 / 309

Advancing to step 8:
309 goes into 2085 6 times with a remainder of 231.
Use 6 as the next digit of our solution. 
Result so far: 158376.0
Deduct 1854 from 2085 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 9:
The number 309 fits into 2310 7 times, leaving a remainder of 147.
Record the quotient 7 as the next digit in the result. 
Result so far: 158376.7
Subtract 2163 from 2310 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 10:
The number 309 fits into 1470 4 times, leaving a remainder of 234.
The number 4 becomes the next digit in our result. 
Result so far: 158376.74
Deduct 1236 from 1470 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 11:
309 can be fit into 2340 7 times, resulting in a remainder of 177.
Record the quotient 7 as the next digit in the result. 
Result so far: 158376.747
Subtracting 2163 from 2340 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 12:
309 goes into 1770 5 times with a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 158376.7475
Deduct 1545 from 1770 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 13:
309 goes into 2250 7 times with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 158376.74757
Subtracting 2163 from 2250 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 14:
If we divide 870 by 309, we get 2 and a remainder of 252.
The next digit of our result is 2. 
Result so far: 158376.747572
The remainder is 252 after subtracting 618 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 15:
309 can be fit into 2520 8 times, resulting in a remainder of 48.
The next digit of our result is 8. 
Result so far: 158376.7475728
The remainder is 48 after subtracting 2472 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
309 goes into 480 1 times with a remainder of 171.
The next digit of our result is 1. 
Result so far: 158376.74757281
If we take 309 away from 480, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

After the division, we end up with 158376.74757281 and a remainder of 1.71e-07.
