We divide 82312501 by 644
Let's see how many times 644 fits into 82312501.

Advancing to step 1:
If we divide 8 by 644, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 644

On to step 2:
644 can be fit into 82 0 times, resulting in a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Include the next digit (3) from the dividend after 82, then repeat: 823 / 644

Going ahead to step 3:
644 can be fit into 823 1 times, resulting in a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 644 away from 823, we end up with 179.
Fetch the next digit (1) from the dividend, attach it to 179 and continue: 1791 / 644

Moving on to step 4:
When dividing 1791 by 644, we get 2 with a remainder of 503.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1288 from 1791 and we're left with 503.
Append the next digit (2) from the dividend to 503 and continue with: 5032 / 644

Step 5:
The number 644 fits into 5032 7 times, leaving a remainder of 524.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Subtract 4508 from 5032 to get 524.
Fetch the next digit (5) from the dividend, attach it to 524 and continue: 5245 / 644

Let's proceed to step 6:
The number 644 fits into 5245 8 times, leaving a remainder of 93.
Use 8 as the next digit of our solution. 
Result so far: 1278.0
Subtract 5152 from 5245 to get 93.
Grab the next digit (0) from the dividend, add it to 93, then carry on: 930 / 644

Step 7:
930 divided by 644 is 1 with a remainder of 286.
The number 1 becomes the next digit in our result. 
Result so far: 12781.0
Subtract 644 from 930 to get 286.
Grab the next digit (1) from the dividend, add it to 286, then carry on: 2861 / 644

Moving on to step 8:
The number 644 fits into 2861 4 times, leaving a remainder of 285.
Use 4 as the next digit of our solution. 
Result so far: 127814.0
Deduct 2576 from 2861 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 9:
2850 divided by 644 is 4 with a remainder of 274.
The next digit of our result is 4. 
Result so far: 127814.4
The remainder is 274 after subtracting 2576 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 10:
The number 644 fits into 2740 4 times, leaving a remainder of 164.
The number 4 becomes the next digit in our result. 
Result so far: 127814.44
Subtract 2576 from 2740 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Our division results in 127814.44 with a remaining 0.164.
