89403709 ÷ 65 
We want to figure out the number of times 89403709 can be divided by 65.

On to step 1:
When dividing 8 by 65, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 65

Step 2:
89 divided by 65 is 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 65 from 89 to get 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 65

Step 3:
65 can be fit into 244 3 times, resulting in a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 49 after subtracting 195 from 244.
Grab the next digit (0) from the dividend, add it to 49, then carry on: 490 / 65

Moving on to step 4:
If we divide 490 by 65, we get 7 and a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtract 455 from 490 to get 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 65

On to step 5:
65 can be fit into 353 5 times, resulting in a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 1375.0
Subtracting 325 from 353 leaves us with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 65

Step 6:
287 divided by 65 is 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 13754.0
If we subtract 260 from 287, we get 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 65

Step 7:
If we divide 270 by 65, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 137544.0
Deduct 260 from 270 and we're left with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 65

On to step 8:
When dividing 109 by 65, we get 1 with a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 1375441.0
If we take 65 away from 109, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
440 divided by 65 is 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 1375441.6
If we take 390 away from 440, we end up 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.

Going ahead to step 10:
When dividing 500 by 65, we get 7 with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 1375441.67
Subtracting 455 from 500 leaves us 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.

Advancing to step 11:
65 goes into 450 6 times with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 1375441.676
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.

Let's proceed to step 12:
65 can be fit into 600 9 times, resulting in a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 1375441.6769
If we take 585 away from 600, we end up 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.

Step 13:
When dividing 150 by 65, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 1375441.67692
If we subtract 130 from 150, 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.

Going ahead to step 14:
When dividing 200 by 65, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 1375441.676923
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.

Moving on to step 15:
50 divided by 65 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 1375441.676923
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.

Going ahead to step 16:
The number 65 fits into 500 7 times, leaving a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 1375441.67692307
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.

The final outcome is 1375441.67692307, with a leftover of 4.5e-08.
