We look at the division of 66409401 by 884 
Let's see how many times 884 fits into 66409401.

Step 1:
6 divided by 884 is 0 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.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 884

Going ahead to step 2:
884 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 subtract 0 from 66, we get 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 884

On to step 3:
The number 884 fits into 664 0 times, leaving a remainder of 664.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 664 and we're left with 664.
Include the next digit (0) from the dividend after 664, then repeat: 6640 / 884

Going ahead to step 4:
884 can be fit into 6640 7 times, resulting in a remainder of 452.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 6188 from 6640 to get 452.
Append the next digit (9) from the dividend to 452 and continue with: 4529 / 884

On to step 5:
884 can be fit into 4529 5 times, resulting in a remainder of 109.
The next digit of our result is 5. 
Result so far: 75.0
The remainder is 109 after subtracting 4420 from 4529.
Fetch the next digit (4) from the dividend, attach it to 109 and continue: 1094 / 884

Let's proceed to step 6:
1094 divided by 884 is 1 with a remainder of 210.
Use 1 as the next digit of our solution. 
Result so far: 751.0
If we subtract 884 from 1094, we get 210.
Bring next digit (0) of the dividend behind the 210 and repeat the process: 2100 / 884

Advancing to step 7:
884 can be fit into 2100 2 times, resulting in a remainder of 332.
Use 2 as the next digit of our solution. 
Result so far: 7512.0
Subtracting 1768 from 2100 leaves us with 332.
Bring next digit (1) of the dividend behind the 332 and repeat the process: 3321 / 884

Step 8:
If we divide 3321 by 884, we get 3 and a remainder of 669.
Use 3 as the next digit of our solution. 
Result so far: 75123.0
Deduct 2652 from 3321 and we're left with 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Advancing to step 9:
884 can be fit into 6690 7 times, resulting in a remainder of 502.
Record the quotient 7 as the next digit in the result. 
Result so far: 75123.7
The remainder is 502 after subtracting 6188 from 6690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Advancing to step 10:
5020 divided by 884 is 5 with a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 75123.75
The remainder is 600 after subtracting 4420 from 5020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 11:
The number 884 fits into 6000 6 times, leaving a remainder of 696.
The next digit of our result is 6. 
Result so far: 75123.756
If we take 5304 away from 6000, we end up with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Let's proceed to step 12:
6960 divided by 884 is 7 with a remainder of 772.
The number 7 becomes the next digit in our result. 
Result so far: 75123.7567
Subtracting 6188 from 6960 leaves us with 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Advancing to step 13:
When dividing 7720 by 884, we get 8 with a remainder of 648.
The number 8 becomes the next digit in our result. 
Result so far: 75123.75678
If we take 7072 away from 7720, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 14:
The number 884 fits into 6480 7 times, leaving a remainder of 292.
Put 7 as the next digit of the answer. 
Result so far: 75123.756787
Subtract 6188 from 6480 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 15:
884 goes into 2920 3 times with a remainder of 268.
The number 3 becomes the next digit in our result. 
Result so far: 75123.7567873
The remainder is 268 after subtracting 2652 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 16:
2680 divided by 884 is 3 with a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 75123.75678733
Deduct 2652 from 2680 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 75123.75678733, and the remainder is 2.8e-08.
