We're dividing 43938138 by 13 
We're looking to find how many times 13 goes into 43938138.

Advancing to step 1:
The number 13 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 13

Moving on to step 2:
The number 13 fits into 43 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
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 / 13

Step 3:
49 divided by 13 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 39 away from 49, we end up with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 13

Advancing to step 4:
103 divided by 13 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 337.0
Subtract 91 from 103 to get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 13

Step 5:
The number 13 fits into 128 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 3379.0
Subtract 117 from 128 to get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 13

Step 6:
13 goes into 111 8 times with a remainder of 7.
The next digit of our result is 8. 
Result so far: 33798.0
If we take 104 away from 111, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 13

Step 7:
When dividing 73 by 13, we get 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 337985.0
The remainder is 8 after subtracting 65 from 73.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 13

Moving on to step 8:
13 goes into 88 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 3379856.0
Deduct 78 from 88 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 13, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 3379856.7
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
13 can be fit into 90 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 3379856.76
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
120 divided by 13 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 3379856.769
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
When dividing 30 by 13, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 3379856.7692
Subtracting 26 from 30 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3379856.76923
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3379856.76923
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
100 divided by 13 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 3379856.7692307
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 16:
The number 13 fits into 90 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 3379856.76923076
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 3379856.76923076 and a remainder of 1.2e-08.
