We look at the division of 785404 by 66 
We want to figure out the number of times 785404 can be divided by 66.

On to step 1:
When dividing 7 by 66, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 66

Going ahead to step 2:
If we divide 78 by 66, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 66 from 78 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 66

Step 3:
If we divide 125 by 66, we get 1 and a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 66 from 125 leaves us with 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 66

Step 4:
The number 66 fits into 594 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 119.0
If we subtract 594 from 594, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 66

On to step 5:
When dividing 0 by 66, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1190.0
If we take 0 away from 0, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 66

Step 6:
If we divide 4 by 66, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 11900.0
If we take 0 away from 4, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
66 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11900.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
If we divide 400 by 66, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 11900.06
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
The number 66 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 11900.06
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 66 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 11900.0606
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
66 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11900.0606
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
The number 66 fits into 400 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 11900.060606
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
66 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 11900.060606
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
When dividing 400 by 66, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 11900.06060606
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 11900.06060606 and a remainder of 4e-09.
