431645 divided by 39 
We want to divide 431645 by 39.

Step 1:
39 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 39

Let's proceed to 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
The remainder is 4 after subtracting 39 from 43.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 39

Step 3:
If we divide 41 by 39, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 39 from 41 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 39

Step 4:
39 goes into 26 0 times with a remainder of 26.
The next digit of our result is 0. 
Result so far: 110.0
The remainder is 26 after subtracting 0 from 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 39

Advancing to step 5:
If we divide 264 by 39, we get 6 and a remainder of 30.
The next digit of our result is 6. 
Result so far: 1106.0
Subtract 234 from 264 to get 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 39

On to step 6:
39 can be fit into 305 7 times, resulting in a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 11067.0
The remainder is 32 after subtracting 273 from 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
320 divided by 39 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 11067.8
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
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: 11067.82
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
39 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11067.82
Deduct 0 from 20 and we're left 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.

Moving on to step 10:
39 can be fit into 200 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 11067.8205
If we take 195 away from 200, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
39 goes into 50 1 times with a remainder of 11.
The next digit of our result is 1. 
Result so far: 11067.82051
If we subtract 39 from 50, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
39 can be fit into 110 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 11067.820512
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.

Step 13:
39 can be fit into 320 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 11067.8205128
Deduct 312 from 320 and we're left 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.

Moving on to step 14:
80 divided by 39 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 11067.82051282
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 11067.82051282, and the remainder is 2e-09.
