We look at the division of 80864123 by 65 
Our goal is to divide 80864123 by 65.

Let's proceed to step 1:
If we divide 8 by 65, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 65

Going ahead to step 2:
When dividing 80 by 65, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 15 after subtracting 65 from 80.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 65

Advancing to step 3:
65 goes into 158 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 130 from 158 and we're left with 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 65

Moving on to step 4:
If we divide 286 by 65, we get 4 and a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtracting 260 from 286 leaves us with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 65

Moving on to step 5:
The number 65 fits into 264 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 1244.0
The remainder is 4 after subtracting 260 from 264.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 65

Step 6:
When dividing 41 by 65, we get 0 with a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 12440.0
Deduct 0 from 41 and we're left with 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 65

Advancing to step 7:
65 can be fit into 412 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 124406.0
Subtract 390 from 412 to get 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 65

Moving on to step 8:
223 divided by 65 is 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 1244063.0
Subtract 195 from 223 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
280 divided by 65 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1244063.4
Subtracting 260 from 280 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
The number 65 fits into 200 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 1244063.43
If we subtract 195 from 200, we get 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 11:
50 divided by 65 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 1244063.43
If we subtract 0 from 50, we 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 12:
The number 65 fits into 500 7 times, leaving a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 1244063.4307
If we take 455 away from 500, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
450 divided by 65 is 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 1244063.43076
Deduct 390 from 450 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
600 divided by 65 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 1244063.430769
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 15:
65 goes into 150 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 1244063.4307692
Subtracting 130 from 150 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
65 goes into 200 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 1244063.43076923
Subtracting 195 from 200 leaves us 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.

The final outcome is 1244063.43076923, with a leftover of 5e-09.
