Let's divide 391388 by 65
We want to divide 391388 by 65.

Step 1:
When dividing 3 by 65, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 65

On to step 2:
When dividing 39 by 65, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 65

Advancing to step 3:
65 goes into 391 6 times with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 390 from 391 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 65

Going ahead to step 4:
If we divide 13 by 65, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 65

Advancing to step 5:
The number 65 fits into 138 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 602.0
Subtract 130 from 138 to get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 65

Going ahead to step 6:
88 divided by 65 is 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 6021.0
Subtracting 65 from 88 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.

Going ahead to step 7:
If we divide 230 by 65, we get 3 and a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 6021.3
Deduct 195 from 230 and we're left 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:
65 goes into 350 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6021.35
Subtract 325 from 350 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
65 goes into 250 3 times with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 6021.353
If we take 195 away from 250, we end up 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.

On to step 10:
The number 65 fits into 550 8 times, leaving a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 6021.3538
Deduct 520 from 550 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
The number 65 fits into 300 4 times, leaving a remainder of 40.
The next digit of our result is 4. 
Result so far: 6021.35384
Subtracting 260 from 300 leaves us 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:
The number 65 fits into 400 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 6021.353846
If we subtract 390 from 400, we 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.

Step 13:
When dividing 100 by 65, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 6021.3538461
If we subtract 65 from 100, we 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.

Going ahead to step 14:
65 can be fit into 350 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 6021.35384615
Subtracting 325 from 350 leaves us 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.

The final result is 6021.35384615 with a remainder of 2.5e-08.
