439313 ÷ 39 
We want to divide 439313 by 39.

Let's proceed to step 1:
4 divided by 39 is 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.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 39

Going ahead to step 2:
When dividing 43 by 39, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 39 away from 43, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 39

Advancing to step 3:
The number 39 fits into 49 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 39 from 49 and we're left with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 39

Let's proceed to step 4:
39 can be fit into 103 2 times, resulting in a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Subtract 78 from 103 to get 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 39

Moving on to step 5:
39 goes into 251 6 times with a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 1126.0
If we subtract 234 from 251, we get 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 39

Let's proceed to step 6:
When dividing 173 by 39, we get 4 with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 11264.0
Subtract 156 from 173 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
39 goes into 170 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 11264.4
Subtract 156 from 170 to 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.

Going ahead to step 8:
140 divided by 39 is 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 11264.43
Deduct 117 from 140 and we're left with 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:
230 divided by 39 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 11264.435
If we subtract 195 from 230, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
The number 39 fits into 350 8 times, leaving a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 11264.4358
If we take 312 away from 350, we end up 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.

Moving on to step 11:
If we divide 380 by 39, we get 9 and a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 11264.43589
Deduct 351 from 380 and we're left with 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:
290 divided by 39 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 11264.435897
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.

Going ahead to step 13:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 11264.4358974
Deduct 156 from 170 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
39 goes into 140 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 11264.43589743
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Our division results in 11264.43589743 with a remaining 2.3e-08.
