16315086 ÷ 664 
We want to divide 16315086 by 664.

On to step 1:
If we divide 1 by 664, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 664

Let's proceed to step 2:
If we divide 16 by 664, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 664

On to step 3:
163 divided by 664 is 0 with a remainder of 163.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 163, we end up with 163.
Include the next digit (1) from the dividend after 163, then repeat: 1631 / 664

Step 4:
If we divide 1631 by 664, we get 2 and a remainder of 303.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1328 from 1631 and we're left with 303.
Include the next digit (5) from the dividend after 303, then repeat: 3035 / 664

Let's proceed to step 5:
If we divide 3035 by 664, we get 4 and a remainder of 379.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 2656 from 3035 to get 379.
Fetch the next digit (0) from the dividend, attach it to 379 and continue: 3790 / 664

Going ahead to step 6:
664 goes into 3790 5 times with a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
The remainder is 470 after subtracting 3320 from 3790.
Include the next digit (8) from the dividend after 470, then repeat: 4708 / 664

Let's proceed to step 7:
When dividing 4708 by 664, we get 7 with a remainder of 60.
The next digit of our result is 7. 
Result so far: 2457.0
Deduct 4648 from 4708 and we're left with 60.
Take the next digit (6) from the dividend and append it to 60, then repeat: 606 / 664

Let's proceed to step 8:
664 can be fit into 606 0 times, resulting in a remainder of 606.
The next digit of our result is 0. 
Result so far: 24570.0
Deduct 0 from 606 and we're left with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

On to step 9:
664 goes into 6060 9 times with a remainder of 84.
Put 9 as the next digit of the answer. 
Result so far: 24570.9
If we take 5976 away from 6060, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 10:
If we divide 840 by 664, we get 1 and a remainder of 176.
Put 1 as the next digit of the answer. 
Result so far: 24570.91
If we subtract 664 from 840, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 11:
664 can be fit into 1760 2 times, resulting in a remainder of 432.
Put 2 as the next digit of the answer. 
Result so far: 24570.912
If we take 1328 away from 1760, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 12:
The number 664 fits into 4320 6 times, leaving a remainder of 336.
Record the quotient 6 as the next digit in the result. 
Result so far: 24570.9126
Subtract 3984 from 4320 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 13:
If we divide 3360 by 664, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 24570.91265
If we take 3320 away from 3360, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
The number 664 fits into 400 0 times, leaving a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 24570.91265
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 15:
When dividing 4000 by 664, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 24570.9126506
If we subtract 3984 from 4000, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 16:
160 divided by 664 is 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 24570.9126506
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 24570.9126506, with a leftover of 1.6e-07.
