138993 ÷ 65 
Let's see how many times 65 fits into 138993.

Advancing to step 1:
When dividing 1 by 65, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 65

Advancing to step 2:
13 divided by 65 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 65

Going ahead to step 3:
65 can be fit into 138 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 130 from 138 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 65

Advancing to step 4:
The number 65 fits into 89 1 times, leaving a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 65 from 89 leaves us with 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 65

Step 5:
If we divide 249 by 65, we get 3 and a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 213.0
Deduct 195 from 249 and we're left with 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 65

Moving on to step 6:
If we divide 543 by 65, we get 8 and a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 2138.0
Subtracting 520 from 543 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
65 goes into 230 3 times with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 2138.3
If we take 195 away from 230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
The number 65 fits into 350 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2138.35
The remainder is 25 after subtracting 325 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
250 divided by 65 is 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 2138.353
If we subtract 195 from 250, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
If we divide 550 by 65, we get 8 and a remainder of 30.
The next digit of our result is 8. 
Result so far: 2138.3538
If we subtract 520 from 550, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
65 goes into 300 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 2138.35384
The remainder is 40 after subtracting 260 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
400 divided by 65 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 2138.353846
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
If we divide 100 by 65, we get 1 and a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 2138.3538461
If we take 65 away from 100, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
65 can be fit into 350 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2138.35384615
If we take 325 away from 350, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 2138.35384615 with a remaining 2.5e-08.
