87317986 ÷ 65 
We want to figure out the number of times 87317986 can be divided by 65.

Advancing to step 1:
If we divide 8 by 65, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 65

Advancing to step 2:
If we divide 87 by 65, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 65 from 87, we get 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 65

Let's proceed to step 3:
If we divide 223 by 65, we get 3 and a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 28 after subtracting 195 from 223.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 65

On to step 4:
The number 65 fits into 281 4 times, leaving a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 134.0
Subtracting 260 from 281 leaves us with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 65

Going ahead to step 5:
65 can be fit into 217 3 times, resulting in a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 1343.0
If we take 195 away from 217, we end up with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 65

On to step 6:
The number 65 fits into 229 3 times, leaving a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 13433.0
If we subtract 195 from 229, we get 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 65

Advancing to step 7:
65 can be fit into 348 5 times, resulting in a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 134335.0
Deduct 325 from 348 and we're left with 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 65

On to step 8:
When dividing 236 by 65, we get 3 with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 1343353.0
Deduct 195 from 236 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
65 can be fit into 410 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 1343353.6
The remainder is 20 after subtracting 390 from 410.
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:
200 divided by 65 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 1343353.63
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.

Let's proceed to step 11:
65 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 1343353.63
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.

Moving on to step 12:
500 divided by 65 is 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 1343353.6307
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.

Advancing to step 13:
The number 65 fits into 450 6 times, leaving a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 1343353.63076
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.
The next digit of our result is 9. 
Result so far: 1343353.630769
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.

Going ahead to step 15:
If we divide 150 by 65, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 1343353.6307692
If we take 130 away from 150, we end up 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:
When dividing 200 by 65, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 1343353.63076923
Deduct 195 from 200 and we're left 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.

In conclusion, the division gives 1343353.63076923 with a balance of 5e-09.
