We're dividing 66945303 by 810 
We're looking to find how many times 810 goes into 66945303.

Advancing to step 1:
The number 810 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 810

Let's proceed to step 2:
66 divided by 810 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 810

Step 3:
810 goes into 669 0 times with a remainder of 669.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 669 after subtracting 0 from 669.
Append the next digit (4) from the dividend to 669 and continue with: 6694 / 810

Advancing to step 4:
810 goes into 6694 8 times with a remainder of 214.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 6480 from 6694 leaves us with 214.
Fetch the next digit (5) from the dividend, attach it to 214 and continue: 2145 / 810

Advancing to step 5:
The number 810 fits into 2145 2 times, leaving a remainder of 525.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Deduct 1620 from 2145 and we're left with 525.
Append the next digit (3) from the dividend to 525 and continue with: 5253 / 810

Let's proceed to step 6:
If we divide 5253 by 810, we get 6 and a remainder of 393.
Record the quotient 6 as the next digit in the result. 
Result so far: 826.0
If we take 4860 away from 5253, we end up with 393.
Append the next digit (0) from the dividend to 393 and continue with: 3930 / 810

On to step 7:
810 goes into 3930 4 times with a remainder of 690.
Write down 4 as next digit of the result. 
Result so far: 8264.0
Subtract 3240 from 3930 to get 690.
Include the next digit (3) from the dividend after 690, then repeat: 6903 / 810

Advancing to step 8:
The number 810 fits into 6903 8 times, leaving a remainder of 423.
Put 8 as the next digit of the answer. 
Result so far: 82648.0
If we subtract 6480 from 6903, we get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

On to step 9:
810 can be fit into 4230 5 times, resulting in a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 82648.5
If we subtract 4050 from 4230, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
If we divide 1800 by 810, we get 2 and a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 82648.52
The remainder is 180 after subtracting 1620 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
If we divide 1800 by 810, we get 2 and a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 82648.522
Subtracting 1620 from 1800 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 82648.522 with a remaining 0.018.
