80501670 divided by 813 
We want to divide 80501670 by 813.

Advancing to step 1:
The number 813 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 813

On to step 2:
813 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 813

Advancing to step 3:
If we divide 805 by 813, we get 0 and a remainder of 805.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 805 to get 805.
Take the next digit (0) from the dividend and append it to 805, then repeat: 8050 / 813

Let's proceed to step 4:
If we divide 8050 by 813, we get 9 and a remainder of 733.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 733 after subtracting 7317 from 8050.
Include the next digit (1) from the dividend after 733, then repeat: 7331 / 813

On to step 5:
When dividing 7331 by 813, we get 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we subtract 7317 from 7331, we get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 813

Let's proceed to step 6:
813 goes into 146 0 times with a remainder of 146.
Put 0 as the next digit of the answer. 
Result so far: 990.0
Subtract 0 from 146 to get 146.
Append the next digit (7) from the dividend to 146 and continue with: 1467 / 813

Going ahead to step 7:
If we divide 1467 by 813, we get 1 and a remainder of 654.
Use 1 as the next digit of our solution. 
Result so far: 9901.0
The remainder is 654 after subtracting 813 from 1467.
Include the next digit (0) from the dividend after 654, then repeat: 6540 / 813

Going ahead to step 8:
When dividing 6540 by 813, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 99018.0
The remainder is 36 after subtracting 6504 from 6540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
360 divided by 813 is 0 with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 99018.0
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
3600 divided by 813 is 4 with a remainder of 348.
Put 4 as the next digit of the answer. 
Result so far: 99018.04
Deduct 3252 from 3600 and we're left 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 11:
When dividing 3480 by 813, we get 4 with a remainder of 228.
Use 4 as the next digit of our solution. 
Result so far: 99018.044
Subtract 3252 from 3480 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The quotient of the division is 99018.044, and the remainder is 0.0228.
