Let's divide 16018382 by 644
Let's see how many times 644 fits into 16018382.

Step 1:
644 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 644

Let's proceed to step 2:
644 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 644

Step 3:
When dividing 160 by 644, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 160, we get 160.
Append the next digit (1) from the dividend to 160 and continue with: 1601 / 644

Let's proceed to step 4:
The number 644 fits into 1601 2 times, leaving a remainder of 313.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1288 from 1601 and we're left with 313.
Bring next digit (8) of the dividend behind the 313 and repeat the process: 3138 / 644

Step 5:
When dividing 3138 by 644, we get 4 with a remainder of 562.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 2576 from 3138 to get 562.
Take the next digit (3) from the dividend and append it to 562, then repeat: 5623 / 644

Let's proceed to step 6:
If we divide 5623 by 644, we get 8 and a remainder of 471.
Write down 8 as next digit of the result. 
Result so far: 248.0
Deduct 5152 from 5623 and we're left with 471.
Grab the next digit (8) from the dividend, add it to 471, then carry on: 4718 / 644

Moving on to step 7:
644 goes into 4718 7 times with a remainder of 210.
The number 7 becomes the next digit in our result. 
Result so far: 2487.0
Subtracting 4508 from 4718 leaves us with 210.
Take the next digit (2) from the dividend and append it to 210, then repeat: 2102 / 644

Going ahead to step 8:
The number 644 fits into 2102 3 times, leaving a remainder of 170.
The number 3 becomes the next digit in our result. 
Result so far: 24873.0
Subtracting 1932 from 2102 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 9:
644 can be fit into 1700 2 times, resulting in a remainder of 412.
Put 2 as the next digit of the answer. 
Result so far: 24873.2
Subtract 1288 from 1700 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 10:
4120 divided by 644 is 6 with a remainder of 256.
Put 6 as the next digit of the answer. 
Result so far: 24873.26
Subtracting 3864 from 4120 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 11:
If we divide 2560 by 644, we get 3 and a remainder of 628.
Put 3 as the next digit of the answer. 
Result so far: 24873.263
Subtracting 1932 from 2560 leaves us with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 12:
644 can be fit into 6280 9 times, resulting in a remainder of 484.
Use 9 as the next digit of our solution. 
Result so far: 24873.2639
Subtracting 5796 from 6280 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 13:
4840 divided by 644 is 7 with a remainder of 332.
Use 7 as the next digit of our solution. 
Result so far: 24873.26397
If we subtract 4508 from 4840, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 14:
3320 divided by 644 is 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 24873.263975
Subtract 3220 from 3320 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
644 goes into 1000 1 times with a remainder of 356.
Write down 1 as next digit of the result. 
Result so far: 24873.2639751
Subtracting 644 from 1000 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 16:
644 goes into 3560 5 times with a remainder of 340.
The number 5 becomes the next digit in our result. 
Result so far: 24873.26397515
Subtract 3220 from 3560 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

In conclusion, the division gives 24873.26397515 with a balance of 3.4e-07.
