312291 ÷ 65 
Our goal is to divide 312291 by 65.

Let's proceed to step 1:
The number 65 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 65

Let's proceed to step 2:
If we divide 31 by 65, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 65

Let's proceed to step 3:
If we divide 312 by 65, we get 4 and a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 52 after subtracting 260 from 312.
Include the next digit (2) from the dividend after 52, then repeat: 522 / 65

On to step 4:
522 divided by 65 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtract 520 from 522 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 65

Advancing to step 5:
29 divided by 65 is 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 480.0
If we subtract 0 from 29, we get 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 65

Moving on to step 6:
291 divided by 65 is 4 with a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 4804.0
If we subtract 260 from 291, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
65 can be fit into 310 4 times, resulting in a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 4804.4
Subtract 260 from 310 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
If we divide 500 by 65, we get 7 and a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 4804.47
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
65 can be fit into 450 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 4804.476
The remainder is 60 after subtracting 390 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
65 goes into 600 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 4804.4769
If we subtract 585 from 600, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
When dividing 150 by 65, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 4804.47692
Subtract 130 from 150 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
200 divided by 65 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 4804.476923
If we take 195 away from 200, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
The number 65 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4804.476923
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
If we divide 500 by 65, we get 7 and a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 4804.47692307
If we subtract 455 from 500, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 4804.47692307, with a leftover of 4.5e-08.
