Let's divide 54618299 by 648
We want to divide 54618299 by 648.

Going ahead to step 1:
The number 648 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 648

On to step 2:
648 can be fit into 54 0 times, resulting in a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Append the next digit (6) from the dividend to 54 and continue with: 546 / 648

Advancing to step 3:
648 goes into 546 0 times with a remainder of 546.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 546 and we're left with 546.
Fetch the next digit (1) from the dividend, attach it to 546 and continue: 5461 / 648

Let's proceed to step 4:
The number 648 fits into 5461 8 times, leaving a remainder of 277.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 5184 from 5461 leaves us with 277.
Grab the next digit (8) from the dividend, add it to 277, then carry on: 2778 / 648

On to step 5:
648 can be fit into 2778 4 times, resulting in a remainder of 186.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Subtracting 2592 from 2778 leaves us with 186.
Fetch the next digit (2) from the dividend, attach it to 186 and continue: 1862 / 648

Moving on to step 6:
If we divide 1862 by 648, we get 2 and a remainder of 566.
The number 2 becomes the next digit in our result. 
Result so far: 842.0
Subtract 1296 from 1862 to get 566.
Bring next digit (9) of the dividend behind the 566 and repeat the process: 5669 / 648

On to step 7:
648 goes into 5669 8 times with a remainder of 485.
Put 8 as the next digit of the answer. 
Result so far: 8428.0
If we take 5184 away from 5669, we end up with 485.
Include the next digit (9) from the dividend after 485, then repeat: 4859 / 648

Let's proceed to step 8:
648 goes into 4859 7 times with a remainder of 323.
The next digit of our result is 7. 
Result so far: 84287.0
Subtracting 4536 from 4859 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 9:
The number 648 fits into 3230 4 times, leaving a remainder of 638.
Write down 4 as next digit of the result. 
Result so far: 84287.4
Subtract 2592 from 3230 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Step 10:
648 goes into 6380 9 times with a remainder of 548.
Use 9 as the next digit of our solution. 
Result so far: 84287.49
The remainder is 548 after subtracting 5832 from 6380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 11:
When dividing 5480 by 648, we get 8 with a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 84287.498
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.

Advancing to step 12:
If we divide 2960 by 648, we get 4 and a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 84287.4984
Subtracting 2592 from 2960 leaves us with 368.
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 13:
If we divide 3680 by 648, we get 5 and a remainder of 440.
Put 5 as the next digit of the answer. 
Result so far: 84287.49845
Subtract 3240 from 3680 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 14:
648 goes into 4400 6 times with a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 84287.498456
Subtracting 3888 from 4400 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 15:
648 goes into 5120 7 times with a remainder of 584.
Write down 7 as next digit of the result. 
Result so far: 84287.4984567
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.

Step 16:
648 can be fit into 5840 9 times, resulting in a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 84287.49845679
Subtracting 5832 from 5840 leaves us with 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 84287.49845679, and the remainder is 8e-09.
