66670510 ÷ 135 
Let's see how many times 135 fits into 66670510.

Advancing to step 1:
135 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 135

Advancing to step 2:
When dividing 66 by 135, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 135

Let's proceed to step 3:
When dividing 666 by 135, we get 4 with a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 540 from 666 to get 126.
Include the next digit (7) from the dividend after 126, then repeat: 1267 / 135

Step 4:
135 can be fit into 1267 9 times, resulting in a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 1215 from 1267, we get 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 135

Going ahead to step 5:
If we divide 520 by 135, we get 3 and a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 493.0
The remainder is 115 after subtracting 405 from 520.
Append the next digit (5) from the dividend to 115 and continue with: 1155 / 135

Advancing to step 6:
1155 divided by 135 is 8 with a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 4938.0
If we take 1080 away from 1155, we end up with 75.
Fetch the next digit (1) from the dividend, attach it to 75 and continue: 751 / 135

Advancing to step 7:
If we divide 751 by 135, we get 5 and a remainder of 76.
The next digit of our result is 5. 
Result so far: 49385.0
Subtract 675 from 751 to get 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 135

Going ahead to step 8:
The number 135 fits into 760 5 times, leaving a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 493855.0
If we take 675 away from 760, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 9:
The number 135 fits into 850 6 times, leaving a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 493855.6
Subtracting 810 from 850 leaves us 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.

Let's proceed to step 10:
The number 135 fits into 400 2 times, leaving a remainder of 130.
The next digit of our result is 2. 
Result so far: 493855.62
If we subtract 270 from 400, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
135 goes into 1300 9 times with a remainder of 85.
The next digit of our result is 9. 
Result so far: 493855.629
Deduct 1215 from 1300 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 12:
850 divided by 135 is 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 493855.6296
If we subtract 810 from 850, 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 13:
When dividing 400 by 135, we get 2 with a remainder of 130.
The number 2 becomes the next digit in our result. 
Result so far: 493855.62962
If we subtract 270 from 400, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 14:
135 can be fit into 1300 9 times, resulting in a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 493855.629629
The remainder is 85 after subtracting 1215 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 15:
850 divided by 135 is 6 with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 493855.6296296
If we subtract 810 from 850, 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.

On to step 16:
400 divided by 135 is 2 with a remainder of 130.
The next digit of our result is 2. 
Result so far: 493855.62962962
If we take 270 away from 400, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final result is 493855.62962962 with a remainder of 1.3e-07.
