449648 ÷ 39 
We want to divide 449648 by 39.

Moving on to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 39

Advancing to step 2:
When dividing 44 by 39, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 39 from 44 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 39

Advancing to step 3:
59 divided by 39 is 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 39 from 59 and we're left with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 39

Moving on to step 4:
If we divide 206 by 39, we get 5 and a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 115.0
The remainder is 11 after subtracting 195 from 206.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 39

Advancing to step 5:
39 goes into 114 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 1152.0
Deduct 78 from 114 and we're left with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 39

Moving on to step 6:
39 can be fit into 368 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 11529.0
If we take 351 away from 368, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
39 goes into 170 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 11529.4
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
39 can be fit into 140 3 times, resulting in a remainder of 23.
The next digit of our result is 3. 
Result so far: 11529.43
If we subtract 117 from 140, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
39 can be fit into 230 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 11529.435
Deduct 195 from 230 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
39 can be fit into 350 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 11529.4358
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 11529.43589
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
39 goes into 290 7 times with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 11529.435897
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
39 can be fit into 170 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 11529.4358974
If we subtract 156 from 170, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
The number 39 fits into 140 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 11529.43589743
If we subtract 117 from 140, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 11529.43589743, with a leftover of 2.3e-08.
