820187 ÷ 66 
Let's see how many times 66 fits into 820187.

Moving on to step 1:
If we divide 8 by 66, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 66

Step 2:
82 divided by 66 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 66 from 82 to get 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 66

Step 3:
66 goes into 160 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 132 from 160 to get 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 66

Let's proceed to step 4:
When dividing 281 by 66, we get 4 with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtracting 264 from 281 leaves us with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 66

Let's proceed to step 5:
If we divide 178 by 66, we get 2 and a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 1242.0
The remainder is 46 after subtracting 132 from 178.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 66

Let's proceed to step 6:
467 divided by 66 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 12427.0
If we take 462 away from 467, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
66 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 12427.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 66 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 12427.07
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
The number 66 fits into 380 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 12427.075
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
When dividing 500 by 66, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 12427.0757
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
380 divided by 66 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 12427.07575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
66 goes into 500 7 times with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 12427.075757
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
When dividing 380 by 66, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 12427.0757575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
500 divided by 66 is 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 12427.07575757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 12427.07575757, and the remainder is 3.8e-08.
