We're dividing 18698735 by 648 
Our goal is to divide 18698735 by 648.

Moving on to step 1:
648 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 648

On to step 2:
648 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 648

Step 3:
The number 648 fits into 186 0 times, leaving a remainder of 186.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 186 and we're left with 186.
Take the next digit (9) from the dividend and append it to 186, then repeat: 1869 / 648

Moving on to step 4:
If we divide 1869 by 648, we get 2 and a remainder of 573.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1296 away from 1869, we end up with 573.
Bring next digit (8) of the dividend behind the 573 and repeat the process: 5738 / 648

Going ahead to step 5:
5738 divided by 648 is 8 with a remainder of 554.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 5184 away from 5738, we end up with 554.
Append the next digit (7) from the dividend to 554 and continue with: 5547 / 648

Advancing to step 6:
5547 divided by 648 is 8 with a remainder of 363.
Record the quotient 8 as the next digit in the result. 
Result so far: 288.0
If we take 5184 away from 5547, we end up with 363.
Grab the next digit (3) from the dividend, add it to 363, then carry on: 3633 / 648

On to step 7:
3633 divided by 648 is 5 with a remainder of 393.
Use 5 as the next digit of our solution. 
Result so far: 2885.0
If we subtract 3240 from 3633, we get 393.
Include the next digit (5) from the dividend after 393, then repeat: 3935 / 648

Moving on to step 8:
When dividing 3935 by 648, we get 6 with a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 28856.0
If we subtract 3888 from 3935, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
If we divide 470 by 648, we get 0 and a remainder of 470.
Use 0 as the next digit of our solution. 
Result so far: 28856.0
If we subtract 0 from 470, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 10:
648 goes into 4700 7 times with a remainder of 164.
Put 7 as the next digit of the answer. 
Result so far: 28856.07
Deduct 4536 from 4700 and we're left 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.

Advancing to step 11:
If we divide 1640 by 648, we get 2 and a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 28856.072
Deduct 1296 from 1640 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 12:
If we divide 3440 by 648, we get 5 and a remainder of 200.
The next digit of our result is 5. 
Result so far: 28856.0725
Subtract 3240 from 3440 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
The number 648 fits into 2000 3 times, leaving a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 28856.07253
The remainder is 56 after subtracting 1944 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
648 can be fit into 560 0 times, resulting in a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 28856.07253
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 15:
When dividing 5600 by 648, we get 8 with a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 28856.0725308
Subtracting 5184 from 5600 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 16:
4160 divided by 648 is 6 with a remainder of 272.
Put 6 as the next digit of the answer. 
Result so far: 28856.07253086
Subtract 3888 from 4160 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final result is 28856.07253086 with a remainder of 2.72e-07.
