Let's divide 405144 by 65
We want to figure out the number of times 405144 can be divided by 65.

Going ahead to step 1:
4 divided by 65 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 65

Advancing to step 2:
40 divided by 65 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 65

Step 3:
When dividing 405 by 65, we get 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 390 away from 405, we end up with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 65

Going ahead to step 4:
151 divided by 65 is 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we take 130 away from 151, we end up with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 65

Going ahead to step 5:
65 can be fit into 214 3 times, resulting in a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 623.0
Subtracting 195 from 214 leaves us with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 65

Step 6:
194 divided by 65 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 6232.0
Deduct 130 from 194 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
640 divided by 65 is 9 with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 6232.9
Subtract 585 from 640 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 8:
550 divided by 65 is 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 6232.98
If we take 520 away from 550, we end up 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.

Step 9:
300 divided by 65 is 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 6232.984
Subtract 260 from 300 to 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.

Step 10:
400 divided by 65 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 6232.9846
Subtracting 390 from 400 leaves us 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.

Step 11:
When dividing 100 by 65, we get 1 with a remainder of 35.
The next digit of our result is 1. 
Result so far: 6232.98461
Subtracting 65 from 100 leaves us 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 12:
65 goes into 350 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 6232.984615
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.

On to step 13:
65 can be fit into 250 3 times, resulting in a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 6232.9846153
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.

Let's proceed to step 14:
550 divided by 65 is 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 6232.98461538
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.

Our division results in 6232.98461538 with a remaining 3e-08.
