86245889 ÷ 65 
We want to divide 86245889 by 65.

Step 1:
The number 65 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 65

Going ahead to step 2:
65 goes into 86 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 65 from 86 and we're left with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 65

Step 3:
212 divided by 65 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 195 from 212, we get 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 65

Step 4:
65 goes into 174 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Subtract 130 from 174 to get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 65

Step 5:
When dividing 445 by 65, we get 6 with a remainder of 55.
The next digit of our result is 6. 
Result so far: 1326.0
Subtract 390 from 445 to get 55.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 65

Moving on to step 6:
When dividing 558 by 65, we get 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 13268.0
Subtract 520 from 558 to get 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 65

On to step 7:
65 goes into 388 5 times with a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 132685.0
If we take 325 away from 388, we end up with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 65

Step 8:
The number 65 fits into 639 9 times, leaving a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 1326859.0
Subtracting 585 from 639 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 9:
540 divided by 65 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 1326859.8
If we subtract 520 from 540, we 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.

Moving on to step 10:
If we divide 200 by 65, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 1326859.83
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.

On to step 11:
65 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1326859.83
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
65 can be fit into 500 7 times, resulting in a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 1326859.8307
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.

Going ahead to step 13:
The number 65 fits into 450 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 1326859.83076
If we take 390 away from 450, we end up 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.

Let's proceed to step 14:
If we divide 600 by 65, we get 9 and a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 1326859.830769
Deduct 585 from 600 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 15:
The number 65 fits into 150 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 1326859.8307692
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.

On to step 16:
200 divided by 65 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 1326859.83076923
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.

The final result is 1326859.83076923 with a remainder of 5e-09.
