We're dividing 66042531 by 649 
We want to divide 66042531 by 649.

Step 1:
649 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 649

On to step 2:
When dividing 66 by 649, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 649

Moving on to step 3:
When dividing 660 by 649, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 649 away from 660, we end up with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 649

On to step 4:
If we divide 114 by 649, we get 0 and a remainder of 114.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 114 to get 114.
Bring next digit (2) of the dividend behind the 114 and repeat the process: 1142 / 649

Step 5:
When dividing 1142 by 649, we get 1 with a remainder of 493.
Write down 1 as next digit of the result. 
Result so far: 101.0
If we take 649 away from 1142, we end up with 493.
Append the next digit (5) from the dividend to 493 and continue with: 4935 / 649

Moving on to step 6:
When dividing 4935 by 649, we get 7 with a remainder of 392.
Write down 7 as next digit of the result. 
Result so far: 1017.0
The remainder is 392 after subtracting 4543 from 4935.
Include the next digit (3) from the dividend after 392, then repeat: 3923 / 649

Going ahead to step 7:
3923 divided by 649 is 6 with a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 10176.0
If we subtract 3894 from 3923, we get 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 649

Moving on to step 8:
291 divided by 649 is 0 with a remainder of 291.
Record the quotient 0 as the next digit in the result. 
Result so far: 101760.0
Subtract 0 from 291 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Going ahead to step 9:
649 goes into 2910 4 times with a remainder of 314.
The next digit of our result is 4. 
Result so far: 101760.4
Deduct 2596 from 2910 and we're left 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.

Going ahead to step 10:
The number 649 fits into 3140 4 times, leaving a remainder of 544.
Put 4 as the next digit of the answer. 
Result so far: 101760.44
Deduct 2596 from 3140 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

In conclusion, the division gives 101760.44 with a balance of 0.544.
