448816 ÷ 39 
We want to figure out the number of times 448816 can be divided by 39.

On to step 1:
39 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
If we take 0 away from 4, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 39

Step 2:
The number 39 fits into 44 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 39 from 44 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 39

On to step 3:
If we divide 58 by 39, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 19 after subtracting 39 from 58.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 39

Advancing to step 4:
The number 39 fits into 198 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 115.0
Subtract 195 from 198 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 39

Step 5:
39 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 1150.0
If we take 0 away from 31, we end up with 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 39

Advancing to step 6:
When dividing 316 by 39, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 11508.0
If we subtract 312 from 316, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
40 divided by 39 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 11508.1
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
The number 39 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 11508.1
Deduct 0 from 10 and we're left 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.

Going ahead to step 9:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 11508.102
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
220 divided by 39 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 11508.1025
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
39 goes into 250 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 11508.10256
The remainder is 16 after subtracting 234 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
39 can be fit into 160 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 11508.102564
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
If we divide 40 by 39, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 11508.1025641
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
39 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 11508.1025641
Subtracting 0 from 10 leaves us 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.

The final result is 11508.1025641 with a remainder of 1e-08.
