We're dividing 436239 by 39 
We're looking to find how many times 39 goes into 436239.

Going ahead to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 39

Advancing to step 2:
39 goes into 43 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 4 after subtracting 39 from 43.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 39

Advancing to step 3:
The number 39 fits into 46 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 7 after subtracting 39 from 46.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 39

Moving on to step 4:
The number 39 fits into 72 1 times, leaving a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 111.0
The remainder is 33 after subtracting 39 from 72.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 39

Let's proceed to step 5:
The number 39 fits into 333 8 times, leaving a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 1118.0
Deduct 312 from 333 and we're left with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 39

Advancing to step 6:
If we divide 219 by 39, we get 5 and a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 11185.0
Subtracting 195 from 219 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
When dividing 240 by 39, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 11185.6
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
The number 39 fits into 60 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 11185.61
The remainder is 21 after subtracting 39 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
210 divided by 39 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 11185.615
If we take 195 away from 210, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
39 can be fit into 150 3 times, resulting in a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 11185.6153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
330 divided by 39 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 11185.61538
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
When dividing 180 by 39, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 11185.615384
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
240 divided by 39 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 11185.6153846
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
When dividing 60 by 39, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 11185.61538461
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 11185.61538461 with a balance of 2.1e-08.
