66869118 ÷ 811 
We want to figure out the number of times 66869118 can be divided by 811.

Moving on to step 1:
811 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 811

Advancing to step 2:
If we divide 66 by 811, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 811

On to step 3:
When dividing 668 by 811, we get 0 with a remainder of 668.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 668 after subtracting 0 from 668.
Bring next digit (6) of the dividend behind the 668 and repeat the process: 6686 / 811

Let's proceed to step 4:
811 goes into 6686 8 times with a remainder of 198.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 6488 from 6686 leaves us with 198.
Bring next digit (9) of the dividend behind the 198 and repeat the process: 1989 / 811

Advancing to step 5:
When dividing 1989 by 811, we get 2 with a remainder of 367.
The next digit of our result is 2. 
Result so far: 82.0
Subtract 1622 from 1989 to get 367.
Grab the next digit (1) from the dividend, add it to 367, then carry on: 3671 / 811

Advancing to step 6:
811 can be fit into 3671 4 times, resulting in a remainder of 427.
Use 4 as the next digit of our solution. 
Result so far: 824.0
If we take 3244 away from 3671, we end up with 427.
Include the next digit (1) from the dividend after 427, then repeat: 4271 / 811

Let's proceed to step 7:
811 can be fit into 4271 5 times, resulting in a remainder of 216.
The number 5 becomes the next digit in our result. 
Result so far: 8245.0
Subtract 4055 from 4271 to get 216.
Include the next digit (8) from the dividend after 216, then repeat: 2168 / 811

Advancing to step 8:
The number 811 fits into 2168 2 times, leaving a remainder of 546.
The number 2 becomes the next digit in our result. 
Result so far: 82452.0
Subtracting 1622 from 2168 leaves us with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

On to step 9:
The number 811 fits into 5460 6 times, leaving a remainder of 594.
Record the quotient 6 as the next digit in the result. 
Result so far: 82452.6
Subtracting 4866 from 5460 leaves us with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Going ahead to step 10:
If we divide 5940 by 811, we get 7 and a remainder of 263.
Use 7 as the next digit of our solution. 
Result so far: 82452.67
The remainder is 263 after subtracting 5677 from 5940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 11:
If we divide 2630 by 811, we get 3 and a remainder of 197.
Use 3 as the next digit of our solution. 
Result so far: 82452.673
If we subtract 2433 from 2630, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 12:
If we divide 1970 by 811, we get 2 and a remainder of 348.
Use 2 as the next digit of our solution. 
Result so far: 82452.6732
If we take 1622 away from 1970, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 13:
811 goes into 3480 4 times with a remainder of 236.
The next digit of our result is 4. 
Result so far: 82452.67324
Subtract 3244 from 3480 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 14:
When dividing 2360 by 811, we get 2 with a remainder of 738.
Record the quotient 2 as the next digit in the result. 
Result so far: 82452.673242
If we subtract 1622 from 2360, we get 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Step 15:
811 goes into 7380 9 times with a remainder of 81.
The next digit of our result is 9. 
Result so far: 82452.6732429
Subtract 7299 from 7380 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 16:
If we divide 810 by 811, we get 0 and a remainder of 810.
The number 0 becomes the next digit in our result. 
Result so far: 82452.6732429
Deduct 0 from 810 and we're left with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

The final result is 82452.6732429 with a remainder of 8.1e-07.
