We're dividing 66804249 by 661 
We want to divide 66804249 by 661.

Let's proceed to step 1:
661 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 661

Step 2:
661 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 661

Step 3:
661 goes into 668 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 661 from 668 to get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 661

Going ahead to step 4:
661 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 70 leaves us with 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 661

On to step 5:
If we divide 704 by 661, we get 1 and a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtract 661 from 704 to get 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 661

Advancing to step 6:
661 goes into 432 0 times with a remainder of 432.
Write down 0 as next digit of the result. 
Result so far: 1010.0
Subtract 0 from 432 to get 432.
Include the next digit (4) from the dividend after 432, then repeat: 4324 / 661

Let's proceed to step 7:
661 can be fit into 4324 6 times, resulting in a remainder of 358.
The next digit of our result is 6. 
Result so far: 10106.0
If we take 3966 away from 4324, we end up with 358.
Bring next digit (9) of the dividend behind the 358 and repeat the process: 3589 / 661

Moving on to step 8:
When dividing 3589 by 661, we get 5 with a remainder of 284.
The next digit of our result is 5. 
Result so far: 101065.0
The remainder is 284 after subtracting 3305 from 3589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 9:
If we divide 2840 by 661, we get 4 and a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 101065.4
If we subtract 2644 from 2840, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 10:
The number 661 fits into 1960 2 times, leaving a remainder of 638.
Write down 2 as next digit of the result. 
Result so far: 101065.42
Subtracting 1322 from 1960 leaves us with 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 11:
661 goes into 6380 9 times with a remainder of 431.
The number 9 becomes the next digit in our result. 
Result so far: 101065.429
Deduct 5949 from 6380 and we're left with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

On to step 12:
When dividing 4310 by 661, we get 6 with a remainder of 344.
The number 6 becomes the next digit in our result. 
Result so far: 101065.4296
If we subtract 3966 from 4310, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 13:
661 goes into 3440 5 times with a remainder of 135.
The next digit of our result is 5. 
Result so far: 101065.42965
If we take 3305 away from 3440, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 14:
The number 661 fits into 1350 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 101065.429652
If we subtract 1322 from 1350, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 15:
280 divided by 661 is 0 with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 101065.429652
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 16:
If we divide 2800 by 661, we get 4 and a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 101065.42965204
Subtract 2644 from 2800 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

After the division, we end up with 101065.42965204 and a remainder of 1.56e-07.
