We divide 12046408 by 644
We want to divide 12046408 by 644.

Advancing to step 1:
If we divide 1 by 644, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 644

Advancing to step 2:
644 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 644

Let's proceed to step 3:
If we divide 120 by 644, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 120 and we're left with 120.
Fetch the next digit (4) from the dividend, attach it to 120 and continue: 1204 / 644

Let's proceed to step 4:
644 goes into 1204 1 times with a remainder of 560.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 644 from 1204 to get 560.
Grab the next digit (6) from the dividend, add it to 560, then carry on: 5606 / 644

Step 5:
The number 644 fits into 5606 8 times, leaving a remainder of 454.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 5152 from 5606 to get 454.
Append the next digit (4) from the dividend to 454 and continue with: 4544 / 644

Let's proceed to step 6:
If we divide 4544 by 644, we get 7 and a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 187.0
The remainder is 36 after subtracting 4508 from 4544.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 644

On to step 7:
360 divided by 644 is 0 with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 1870.0
If we take 0 away from 360, we end up with 360.
Grab the next digit (8) from the dividend, add it to 360, then carry on: 3608 / 644

On to step 8:
3608 divided by 644 is 5 with a remainder of 388.
Use 5 as the next digit of our solution. 
Result so far: 18705.0
Deduct 3220 from 3608 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 9:
If we divide 3880 by 644, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 18705.6
Subtracting 3864 from 3880 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 644, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 18705.6
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
1600 divided by 644 is 2 with a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 18705.602
The remainder is 312 after subtracting 1288 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 12:
644 can be fit into 3120 4 times, resulting in a remainder of 544.
Use 4 as the next digit of our solution. 
Result so far: 18705.6024
The remainder is 544 after subtracting 2576 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 13:
644 goes into 5440 8 times with a remainder of 288.
The next digit of our result is 8. 
Result so far: 18705.60248
If we take 5152 away from 5440, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 14:
If we divide 2880 by 644, we get 4 and a remainder of 304.
Record the quotient 4 as the next digit in the result. 
Result so far: 18705.602484
Subtract 2576 from 2880 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 15:
644 goes into 3040 4 times with a remainder of 464.
Put 4 as the next digit of the answer. 
Result so far: 18705.6024844
If we subtract 2576 from 3040, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The quotient of the division is 18705.6024844, and the remainder is 4.64e-06.
