We look at the division of 400839 by 65 
Our goal is to divide 400839 by 65.

Let's proceed to step 1:
65 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 65

Moving on to step 2:
The number 65 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 65

Advancing to step 3:
400 divided by 65 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 390 from 400 and we're left with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 65

Going ahead to step 4:
108 divided by 65 is 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
If we subtract 65 from 108, we get 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 65

Let's proceed to step 5:
65 goes into 433 6 times with a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 616.0
The remainder is 43 after subtracting 390 from 433.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 65

Let's proceed to step 6:
The number 65 fits into 439 6 times, leaving a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 6166.0
If we subtract 390 from 439, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
When dividing 490 by 65, we get 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 6166.7
Subtract 455 from 490 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.

On to step 8:
65 can be fit into 350 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 6166.75
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 9:
The number 65 fits into 250 3 times, leaving a remainder of 55.
The next digit of our result is 3. 
Result so far: 6166.753
Subtract 195 from 250 to 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.

Going ahead to step 10:
If we divide 550 by 65, we get 8 and a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 6166.7538
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.

Let's proceed to step 11:
When dividing 300 by 65, we get 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 6166.75384
If we subtract 260 from 300, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
65 can be fit into 400 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 6166.753846
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.

Let's proceed to step 13:
100 divided by 65 is 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 6166.7538461
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.

Step 14:
65 goes into 350 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 6166.75384615
Deduct 325 from 350 and we're left 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 6166.75384615 with a remaining 2.5e-08.
