56366508 divided by 644 
We want to divide 56366508 by 644.

On to step 1:
5 divided by 644 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 644

Going ahead to step 2:
If we divide 56 by 644, we get 0 and a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Bring next digit (3) of the dividend behind the 56 and repeat the process: 563 / 644

On to step 3:
644 can be fit into 563 0 times, resulting in a remainder of 563.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 563 to get 563.
Include the next digit (6) from the dividend after 563, then repeat: 5636 / 644

On to step 4:
The number 644 fits into 5636 8 times, leaving a remainder of 484.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 5152 from 5636 to get 484.
Take the next digit (6) from the dividend and append it to 484, then repeat: 4846 / 644

Step 5:
The number 644 fits into 4846 7 times, leaving a remainder of 338.
The next digit of our result is 7. 
Result so far: 87.0
Subtracting 4508 from 4846 leaves us with 338.
Append the next digit (5) from the dividend to 338 and continue with: 3385 / 644

Going ahead to step 6:
3385 divided by 644 is 5 with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 875.0
Subtract 3220 from 3385 to get 165.
Append the next digit (0) from the dividend to 165 and continue with: 1650 / 644

Moving on to step 7:
1650 divided by 644 is 2 with a remainder of 362.
The next digit of our result is 2. 
Result so far: 8752.0
If we take 1288 away from 1650, we end up with 362.
Append the next digit (8) from the dividend to 362 and continue with: 3628 / 644

On to step 8:
3628 divided by 644 is 5 with a remainder of 408.
Record the quotient 5 as the next digit in the result. 
Result so far: 87525.0
Subtracting 3220 from 3628 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 9:
When dividing 4080 by 644, we get 6 with a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 87525.6
Subtract 3864 from 4080 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 10:
The number 644 fits into 2160 3 times, leaving a remainder of 228.
The number 3 becomes the next digit in our result. 
Result so far: 87525.63
The remainder is 228 after subtracting 1932 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 11:
The number 644 fits into 2280 3 times, leaving a remainder of 348.
Record the quotient 3 as the next digit in the result. 
Result so far: 87525.633
Subtracting 1932 from 2280 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

The quotient of the division is 87525.633, and the remainder is 0.0348.
