We're dividing 2099357 by 648 
We want to divide 2099357 by 648.

Step 1:
648 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 648

Advancing to step 2:
When dividing 20 by 648, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 648

Going ahead to step 3:
When dividing 209 by 648, we get 0 with a remainder of 209.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Append the next digit (9) from the dividend to 209 and continue with: 2099 / 648

Advancing to step 4:
2099 divided by 648 is 3 with a remainder of 155.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1944 from 2099 and we're left with 155.
Take the next digit (3) from the dividend and append it to 155, then repeat: 1553 / 648

Let's proceed to step 5:
648 can be fit into 1553 2 times, resulting in a remainder of 257.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtracting 1296 from 1553 leaves us with 257.
Grab the next digit (5) from the dividend, add it to 257, then carry on: 2575 / 648

Advancing to step 6:
The number 648 fits into 2575 3 times, leaving a remainder of 631.
Put 3 as the next digit of the answer. 
Result so far: 323.0
If we subtract 1944 from 2575, we get 631.
Take the next digit (7) from the dividend and append it to 631, then repeat: 6317 / 648

Moving on to step 7:
The number 648 fits into 6317 9 times, leaving a remainder of 485.
Write down 9 as next digit of the result. 
Result so far: 3239.0
Subtracting 5832 from 6317 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 8:
The number 648 fits into 4850 7 times, leaving a remainder of 314.
Put 7 as the next digit of the answer. 
Result so far: 3239.7
If we take 4536 away from 4850, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 9:
If we divide 3140 by 648, we get 4 and a remainder of 548.
Use 4 as the next digit of our solution. 
Result so far: 3239.74
Subtract 2592 from 3140 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 10:
648 goes into 5480 8 times with a remainder of 296.
The number 8 becomes the next digit in our result. 
Result so far: 3239.748
If we take 5184 away from 5480, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 11:
If we divide 2960 by 648, we get 4 and a remainder of 368.
The next digit of our result is 4. 
Result so far: 3239.7484
The remainder is 368 after subtracting 2592 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 12:
648 goes into 3680 5 times with a remainder of 440.
Record the quotient 5 as the next digit in the result. 
Result so far: 3239.74845
The remainder is 440 after subtracting 3240 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 13:
If we divide 4400 by 648, we get 6 and a remainder of 512.
Write down 6 as next digit of the result. 
Result so far: 3239.748456
The remainder is 512 after subtracting 3888 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 14:
If we divide 5120 by 648, we get 7 and a remainder of 584.
The next digit of our result is 7. 
Result so far: 3239.7484567
The remainder is 584 after subtracting 4536 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

On to step 15:
If we divide 5840 by 648, we get 9 and a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 3239.74845679
If we subtract 5832 from 5840, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 3239.74845679, and the remainder is 8e-09.
