Let's divide 90506308 by 813
We want to figure out the number of times 90506308 can be divided by 813.

Advancing to step 1:
813 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 813

Moving on to step 2:
90 divided by 813 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (5) from the dividend to 90 and continue with: 905 / 813

Moving on to step 3:
If we divide 905 by 813, we get 1 and a remainder of 92.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 813 from 905 to get 92.
Bring next digit (0) of the dividend behind the 92 and repeat the process: 920 / 813

Step 4:
920 divided by 813 is 1 with a remainder of 107.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 813 from 920 and we're left with 107.
Fetch the next digit (6) from the dividend, attach it to 107 and continue: 1076 / 813

Step 5:
When dividing 1076 by 813, we get 1 with a remainder of 263.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
If we subtract 813 from 1076, we get 263.
Bring next digit (3) of the dividend behind the 263 and repeat the process: 2633 / 813

Let's proceed to step 6:
2633 divided by 813 is 3 with a remainder of 194.
The number 3 becomes the next digit in our result. 
Result so far: 1113.0
Subtracting 2439 from 2633 leaves us with 194.
Take the next digit (0) from the dividend and append it to 194, then repeat: 1940 / 813

Let's proceed to step 7:
The number 813 fits into 1940 2 times, leaving a remainder of 314.
Use 2 as the next digit of our solution. 
Result so far: 11132.0
Subtracting 1626 from 1940 leaves us with 314.
Grab the next digit (8) from the dividend, add it to 314, then carry on: 3148 / 813

Moving on to step 8:
813 can be fit into 3148 3 times, resulting in a remainder of 709.
Write down 3 as next digit of the result. 
Result so far: 111323.0
Subtracting 2439 from 3148 leaves us 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.

Let's proceed to step 9:
813 can be fit into 7090 8 times, resulting in a remainder of 586.
Write down 8 as next digit of the result. 
Result so far: 111323.8
Subtract 6504 from 7090 to get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Advancing to step 10:
5860 divided by 813 is 7 with a remainder of 169.
Use 7 as the next digit of our solution. 
Result so far: 111323.87
The remainder is 169 after subtracting 5691 from 5860.
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 11:
If we divide 1690 by 813, we get 2 and a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 111323.872
If we subtract 1626 from 1690, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
813 can be fit into 640 0 times, resulting in a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 111323.872
Deduct 0 from 640 and we're left with 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 13:
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: 111323.87207
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.

On to step 14:
7090 divided by 813 is 8 with a remainder of 586.
Use 8 as the next digit of our solution. 
Result so far: 111323.872078
Subtracting 6504 from 7090 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Let's proceed to step 15:
When dividing 5860 by 813, we get 7 with a remainder of 169.
Record the quotient 7 as the next digit in the result. 
Result so far: 111323.8720787
Subtract 5691 from 5860 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.

On to step 16:
1690 divided by 813 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 111323.87207872
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.

The quotient of the division is 111323.87207872, and the remainder is 6.4e-08.
