We're dividing 431555 by 39 
We want to figure out the number of times 431555 can be divided by 39.

Moving on to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 39

Step 2:
43 divided by 39 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 39 from 43, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 39

Step 3:
41 divided by 39 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 39 from 41, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 39

Advancing to step 4:
25 divided by 39 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Subtract 0 from 25 to get 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 39

Going ahead to step 5:
39 can be fit into 255 6 times, resulting in a remainder of 21.
The next digit of our result is 6. 
Result so far: 1106.0
The remainder is 21 after subtracting 234 from 255.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 39

Let's proceed to step 6:
If we divide 215 by 39, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 11065.0
If we subtract 195 from 215, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
If we divide 200 by 39, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 11065.5
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
39 goes into 50 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 11065.51
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
If we divide 110 by 39, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 11065.512
Deduct 78 from 110 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
If we divide 320 by 39, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 11065.5128
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
39 can be fit into 80 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 11065.51282
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
39 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11065.51282
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
The number 39 fits into 200 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 11065.5128205
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
39 goes into 50 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 11065.51282051
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 11065.51282051 and a remainder of 1.1e-08.
