Let's divide 66123642 by 909
Let's see how many times 909 fits into 66123642.

Step 1:
6 divided by 909 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 909

Moving on to step 2:
909 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 909

Step 3:
909 can be fit into 661 0 times, resulting in a remainder of 661.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 661 to get 661.
Take the next digit (2) from the dividend and append it to 661, then repeat: 6612 / 909

Step 4:
The number 909 fits into 6612 7 times, leaving a remainder of 249.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 6363 from 6612 to get 249.
Bring next digit (3) of the dividend behind the 249 and repeat the process: 2493 / 909

Moving on to step 5:
2493 divided by 909 is 2 with a remainder of 675.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 1818 from 2493 and we're left with 675.
Append the next digit (6) from the dividend to 675 and continue with: 6756 / 909

Let's proceed to step 6:
909 can be fit into 6756 7 times, resulting in a remainder of 393.
Record the quotient 7 as the next digit in the result. 
Result so far: 727.0
If we subtract 6363 from 6756, we get 393.
Append the next digit (4) from the dividend to 393 and continue with: 3934 / 909

Step 7:
909 goes into 3934 4 times with a remainder of 298.
Use 4 as the next digit of our solution. 
Result so far: 7274.0
Subtract 3636 from 3934 to get 298.
Bring next digit (2) of the dividend behind the 298 and repeat the process: 2982 / 909

Moving on to step 8:
When dividing 2982 by 909, we get 3 with a remainder of 255.
The next digit of our result is 3. 
Result so far: 72743.0
Subtracting 2727 from 2982 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 9:
909 goes into 2550 2 times with a remainder of 732.
Put 2 as the next digit of the answer. 
Result so far: 72743.2
Subtracting 1818 from 2550 leaves us with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Let's proceed to step 10:
When dividing 7320 by 909, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 72743.28
If we take 7272 away from 7320, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
When dividing 480 by 909, we get 0 with a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 72743.28
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 12:
4800 divided by 909 is 5 with a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 72743.2805
The remainder is 255 after subtracting 4545 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 13:
The number 909 fits into 2550 2 times, leaving a remainder of 732.
Use 2 as the next digit of our solution. 
Result so far: 72743.28052
Deduct 1818 from 2550 and we're left with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

On to step 14:
When dividing 7320 by 909, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 72743.280528
If we subtract 7272 from 7320, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 15:
909 goes into 480 0 times with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 72743.280528
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 16:
If we divide 4800 by 909, we get 5 and a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 72743.28052805
If we subtract 4545 from 4800, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Our division results in 72743.28052805 with a remaining 2.55e-07.
