We're dividing 1640701 by 648 
We want to divide 1640701 by 648.

Let's proceed to step 1:
The number 648 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 648

Let's proceed to step 2:
16 divided by 648 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 648

Step 3:
The number 648 fits into 164 0 times, leaving a remainder of 164.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 164, we end up with 164.
Append the next digit (0) from the dividend to 164 and continue with: 1640 / 648

Moving on to step 4:
1640 divided by 648 is 2 with a remainder of 344.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 344 after subtracting 1296 from 1640.
Grab the next digit (7) from the dividend, add it to 344, then carry on: 3447 / 648

Going ahead to step 5:
648 goes into 3447 5 times with a remainder of 207.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 3240 away from 3447, we end up with 207.
Append the next digit (0) from the dividend to 207 and continue with: 2070 / 648

Moving on to step 6:
648 can be fit into 2070 3 times, resulting in a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 253.0
If we take 1944 away from 2070, we end up with 126.
Grab the next digit (1) from the dividend, add it to 126, then carry on: 1261 / 648

Advancing to step 7:
1261 divided by 648 is 1 with a remainder of 613.
Put 1 as the next digit of the answer. 
Result so far: 2531.0
Subtracting 648 from 1261 leaves us with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Let's proceed to step 8:
648 can be fit into 6130 9 times, resulting in a remainder of 298.
Put 9 as the next digit of the answer. 
Result so far: 2531.9
Subtracting 5832 from 6130 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 9:
If we divide 2980 by 648, we get 4 and a remainder of 388.
Use 4 as the next digit of our solution. 
Result so far: 2531.94
Deduct 2592 from 2980 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.

On to step 10:
648 can be fit into 3880 5 times, resulting in a remainder of 640.
Write down 5 as next digit of the result. 
Result so far: 2531.945
Deduct 3240 from 3880 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 11:
If we divide 6400 by 648, we get 9 and a remainder of 568.
The next digit of our result is 9. 
Result so far: 2531.9459
Deduct 5832 from 6400 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Going ahead to step 12:
5680 divided by 648 is 8 with a remainder of 496.
Record the quotient 8 as the next digit in the result. 
Result so far: 2531.94598
Deduct 5184 from 5680 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 13:
If we divide 4960 by 648, we get 7 and a remainder of 424.
The next digit of our result is 7. 
Result so far: 2531.945987
If we take 4536 away from 4960, we end up with 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 14:
4240 divided by 648 is 6 with a remainder of 352.
The next digit of our result is 6. 
Result so far: 2531.9459876
Subtracting 3888 from 4240 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 15:
3520 divided by 648 is 5 with a remainder of 280.
The next digit of our result is 5. 
Result so far: 2531.94598765
The remainder is 280 after subtracting 3240 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The quotient of the division is 2531.94598765, and the remainder is 2.8e-07.
