782357 ÷ 66 
We're looking to find how many times 66 goes into 782357.

Step 1:
66 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 66

Advancing to step 2:
66 goes into 78 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 66 from 78 and we're left with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 66

Moving on to step 3:
When dividing 122 by 66, we get 1 with a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 66 away from 122, we end up with 56.
Include the next digit (3) from the dividend after 56, then repeat: 563 / 66

Moving on to step 4:
When dividing 563 by 66, we get 8 with a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
If we take 528 away from 563, we end up with 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 66

Advancing to step 5:
355 divided by 66 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1185.0
If we subtract 330 from 355, we get 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 66

Advancing to step 6:
If we divide 257 by 66, we get 3 and a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 11853.0
Subtracting 198 from 257 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
The number 66 fits into 590 8 times, leaving a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 11853.8
Deduct 528 from 590 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
The number 66 fits into 620 9 times, leaving a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 11853.89
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
260 divided by 66 is 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 11853.893
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
66 can be fit into 620 9 times, resulting in a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 11853.8939
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
66 goes into 260 3 times with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 11853.89393
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
If we divide 620 by 66, we get 9 and a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 11853.893939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 11853.8939393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 14:
66 goes into 620 9 times with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 11853.89393939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 11853.89393939 with a remainder of 2.6e-08.
