43860500 ÷ 39 
Our goal is to divide 43860500 by 39.

Step 1:
39 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 39

On to step 2:
39 can be fit into 43 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 39 from 43 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 39

Step 3:
The number 39 fits into 48 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 39 away from 48, we end up with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 39

Let's proceed to step 4:
39 goes into 96 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we take 78 away from 96, we end up with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 39

Moving on to step 5:
When dividing 180 by 39, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 1124.0
If we take 156 away from 180, we end up with 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 39

Step 6:
245 divided by 39 is 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 11246.0
If we take 234 away from 245, we end up with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 39

Going ahead to step 7:
39 goes into 110 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 112462.0
If we take 78 away from 110, we end up with 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 39

Going ahead to step 8:
When dividing 320 by 39, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 1124628.0
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.

Step 9:
39 goes into 80 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 1124628.2
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 10:
20 divided by 39 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1124628.2
Subtract 0 from 20 to 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.

Going ahead to step 11:
39 can be fit into 200 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1124628.205
Deduct 195 from 200 and we're left 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.

Going ahead to step 12:
50 divided by 39 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1124628.2051
Subtract 39 from 50 to 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.

On to step 13:
When dividing 110 by 39, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 1124628.20512
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.

Let's proceed to step 14:
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: 1124628.205128
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.

Going ahead to step 15:
When dividing 80 by 39, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1124628.2051282
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.

Advancing to step 16:
When dividing 20 by 39, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1124628.2051282
If we subtract 0 from 20, 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.

After the division, we end up with 1124628.2051282 and a remainder of 2e-08.
