80620501 ÷ 813 
We want to figure out the number of times 80620501 can be divided by 813.

Advancing to step 1:
If we divide 8 by 813, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 813

Step 2:
The number 813 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 813

Advancing to step 3:
When dividing 806 by 813, we get 0 with a remainder of 806.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 806, we get 806.
Fetch the next digit (2) from the dividend, attach it to 806 and continue: 8062 / 813

Let's proceed to step 4:
When dividing 8062 by 813, we get 9 with a remainder of 745.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 745 after subtracting 7317 from 8062.
Fetch the next digit (0) from the dividend, attach it to 745 and continue: 7450 / 813

Advancing to step 5:
If we divide 7450 by 813, we get 9 and a remainder of 133.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 7317 from 7450 to get 133.
Include the next digit (5) from the dividend after 133, then repeat: 1335 / 813

On to step 6:
If we divide 1335 by 813, we get 1 and a remainder of 522.
The next digit of our result is 1. 
Result so far: 991.0
Subtracting 813 from 1335 leaves us with 522.
Include the next digit (0) from the dividend after 522, then repeat: 5220 / 813

Step 7:
813 can be fit into 5220 6 times, resulting in a remainder of 342.
Use 6 as the next digit of our solution. 
Result so far: 9916.0
Deduct 4878 from 5220 and we're left with 342.
Include the next digit (1) from the dividend after 342, then repeat: 3421 / 813

Going ahead to step 8:
If we divide 3421 by 813, we get 4 and a remainder of 169.
Record the quotient 4 as the next digit in the result. 
Result so far: 99164.0
Subtract 3252 from 3421 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 9:
If we divide 1690 by 813, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 99164.2
The remainder is 64 after subtracting 1626 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
640 divided by 813 is 0 with a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 99164.2
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 11:
813 can be fit into 6400 7 times, resulting in a remainder of 709.
Use 7 as the next digit of our solution. 
Result so far: 99164.207
If we subtract 5691 from 6400, we get 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Step 12:
When dividing 7090 by 813, we get 8 with a remainder of 586.
Put 8 as the next digit of the answer. 
Result so far: 99164.2078
The remainder is 586 after subtracting 6504 from 7090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Step 13:
When dividing 5860 by 813, we get 7 with a remainder of 169.
Put 7 as the next digit of the answer. 
Result so far: 99164.20787
If we take 5691 away from 5860, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 14:
When dividing 1690 by 813, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 99164.207872
If we take 1626 away from 1690, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
The number 813 fits into 640 0 times, leaving a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 99164.207872
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 16:
813 can be fit into 6400 7 times, resulting in a remainder of 709.
Put 7 as the next digit of the answer. 
Result so far: 99164.20787207
If we take 5691 away from 6400, we end up with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

After the division, we end up with 99164.20787207 and a remainder of 7.09e-07.
