We look at the division of 50138789 by 65 
Let's see how many times 65 fits into 50138789.

On to step 1:
When dividing 5 by 65, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 65

Step 2:
50 divided by 65 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 65

On to step 3:
The number 65 fits into 501 7 times, leaving a remainder of 46.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 455 from 501 leaves us with 46.
Fetch the next digit (3) from the dividend, attach it to 46 and continue: 463 / 65

On to step 4:
65 goes into 463 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 77.0
If we take 455 away from 463, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 65

Advancing to step 5:
If we divide 88 by 65, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 771.0
The remainder is 23 after subtracting 65 from 88.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 65

Step 6:
65 can be fit into 237 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 7713.0
If we take 195 away from 237, we end up with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 65

On to step 7:
65 can be fit into 428 6 times, resulting in a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 77136.0
If we subtract 390 from 428, we get 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 65

Advancing to step 8:
65 can be fit into 389 5 times, resulting in a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 771365.0
If we subtract 325 from 389, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
65 can be fit into 640 9 times, resulting in a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 771365.9
Subtracting 585 from 640 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
65 goes into 550 8 times with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 771365.98
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 can be fit into 300 4 times, resulting in a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 771365.984
If we take 260 away from 300, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 65 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 771365.9846
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.

Advancing to step 13:
65 goes into 100 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 771365.98461
Subtract 65 from 100 to get 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:
When dividing 350 by 65, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 771365.984615
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.

Advancing to step 15:
If we divide 250 by 65, we get 3 and a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 771365.9846153
Subtracting 195 from 250 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 16:
65 can be fit into 550 8 times, resulting in a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 771365.98461538
Subtract 520 from 550 to 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.

The final result is 771365.98461538 with a remainder of 3e-08.
