We divide 12001104 by 644
We want to divide 12001104 by 644.

Going ahead to step 1:
1 divided by 644 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 644

On to step 2:
When dividing 12 by 644, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 644

On to step 3:
The number 644 fits into 120 0 times, leaving a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 120 and we're left with 120.
Append the next digit (0) from the dividend to 120 and continue with: 1200 / 644

Let's proceed to step 4:
The number 644 fits into 1200 1 times, leaving a remainder of 556.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 644 from 1200 to get 556.
Include the next digit (1) from the dividend after 556, then repeat: 5561 / 644

Advancing to step 5:
The number 644 fits into 5561 8 times, leaving a remainder of 409.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 409 after subtracting 5152 from 5561.
Include the next digit (1) from the dividend after 409, then repeat: 4091 / 644

Going ahead to step 6:
644 goes into 4091 6 times with a remainder of 227.
Write down 6 as next digit of the result. 
Result so far: 186.0
The remainder is 227 after subtracting 3864 from 4091.
Take the next digit (0) from the dividend and append it to 227, then repeat: 2270 / 644

Going ahead to step 7:
The number 644 fits into 2270 3 times, leaving a remainder of 338.
The next digit of our result is 3. 
Result so far: 1863.0
If we take 1932 away from 2270, we end up with 338.
Append the next digit (4) from the dividend to 338 and continue with: 3384 / 644

On to step 8:
3384 divided by 644 is 5 with a remainder of 164.
Use 5 as the next digit of our solution. 
Result so far: 18635.0
If we take 3220 away from 3384, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 9:
If we divide 1640 by 644, we get 2 and a remainder of 352.
The number 2 becomes the next digit in our result. 
Result so far: 18635.2
The remainder is 352 after subtracting 1288 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 10:
3520 divided by 644 is 5 with a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 18635.25
Deduct 3220 from 3520 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
The number 644 fits into 3000 4 times, leaving a remainder of 424.
Use 4 as the next digit of our solution. 
Result so far: 18635.254
Subtract 2576 from 3000 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 12:
644 can be fit into 4240 6 times, resulting in a remainder of 376.
Record the quotient 6 as the next digit in the result. 
Result so far: 18635.2546
The remainder is 376 after subtracting 3864 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 13:
3760 divided by 644 is 5 with a remainder of 540.
Record the quotient 5 as the next digit in the result. 
Result so far: 18635.25465
If we subtract 3220 from 3760, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 14:
644 goes into 5400 8 times with a remainder of 248.
Write down 8 as next digit of the result. 
Result so far: 18635.254658
Subtract 5152 from 5400 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 15:
The number 644 fits into 2480 3 times, leaving a remainder of 548.
Write down 3 as next digit of the result. 
Result so far: 18635.2546583
Deduct 1932 from 2480 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 16:
When dividing 5480 by 644, we get 8 with a remainder of 328.
The number 8 becomes the next digit in our result. 
Result so far: 18635.25465838
Subtracting 5152 from 5480 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

In conclusion, the division gives 18635.25465838 with a balance of 3.28e-07.
