66489935 ÷ 811 
We want to divide 66489935 by 811.

Moving on to step 1:
6 divided by 811 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 811

Step 2:
811 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 811

Advancing to step 3:
811 can be fit into 664 0 times, resulting in a remainder of 664.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 664, we get 664.
Bring next digit (8) of the dividend behind the 664 and repeat the process: 6648 / 811

Advancing to step 4:
811 can be fit into 6648 8 times, resulting in a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 6488 from 6648 leaves us with 160.
Grab the next digit (9) from the dividend, add it to 160, then carry on: 1609 / 811

Going ahead to step 5:
811 can be fit into 1609 1 times, resulting in a remainder of 798.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtracting 811 from 1609 leaves us with 798.
Append the next digit (9) from the dividend to 798 and continue with: 7989 / 811

Let's proceed to step 6:
When dividing 7989 by 811, we get 9 with a remainder of 690.
Use 9 as the next digit of our solution. 
Result so far: 819.0
The remainder is 690 after subtracting 7299 from 7989.
Include the next digit (3) from the dividend after 690, then repeat: 6903 / 811

Let's proceed to step 7:
When dividing 6903 by 811, we get 8 with a remainder of 415.
Use 8 as the next digit of our solution. 
Result so far: 8198.0
Deduct 6488 from 6903 and we're left with 415.
Append the next digit (5) from the dividend to 415 and continue with: 4155 / 811

Going ahead to step 8:
If we divide 4155 by 811, we get 5 and a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 81985.0
If we take 4055 away from 4155, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 9:
If we divide 1000 by 811, we get 1 and a remainder of 189.
The next digit of our result is 1. 
Result so far: 81985.1
If we take 811 away from 1000, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 10:
811 can be fit into 1890 2 times, resulting in a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 81985.12
Subtract 1622 from 1890 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 11:
811 can be fit into 2680 3 times, resulting in a remainder of 247.
Put 3 as the next digit of the answer. 
Result so far: 81985.123
Subtracting 2433 from 2680 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 12:
When dividing 2470 by 811, we get 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 81985.1233
Subtracting 2433 from 2470 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The quotient of the division is 81985.1233, and the remainder is 0.00037.
