We look at the division of 30628953 by 813 
We're looking to find how many times 813 goes into 30628953.

Step 1:
813 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 813

Moving on to step 2:
If we divide 30 by 813, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 813

Step 3:
When dividing 306 by 813, we get 0 with a remainder of 306.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 306 and we're left with 306.
Include the next digit (2) from the dividend after 306, then repeat: 3062 / 813

Let's proceed to step 4:
When dividing 3062 by 813, we get 3 with a remainder of 623.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 2439 from 3062 to get 623.
Bring next digit (8) of the dividend behind the 623 and repeat the process: 6238 / 813

On to step 5:
If we divide 6238 by 813, we get 7 and a remainder of 547.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we take 5691 away from 6238, we end up with 547.
Fetch the next digit (9) from the dividend, attach it to 547 and continue: 5479 / 813

Step 6:
813 can be fit into 5479 6 times, resulting in a remainder of 601.
The next digit of our result is 6. 
Result so far: 376.0
Deduct 4878 from 5479 and we're left with 601.
Bring next digit (5) of the dividend behind the 601 and repeat the process: 6015 / 813

On to step 7:
813 can be fit into 6015 7 times, resulting in a remainder of 324.
Record the quotient 7 as the next digit in the result. 
Result so far: 3767.0
If we take 5691 away from 6015, we end up with 324.
Fetch the next digit (3) from the dividend, attach it to 324 and continue: 3243 / 813

Let's proceed to step 8:
The number 813 fits into 3243 3 times, leaving a remainder of 804.
Use 3 as the next digit of our solution. 
Result so far: 37673.0
The remainder is 804 after subtracting 2439 from 3243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Advancing to step 9:
When dividing 8040 by 813, we get 9 with a remainder of 723.
Put 9 as the next digit of the answer. 
Result so far: 37673.9
Subtract 7317 from 8040 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

On to step 10:
7230 divided by 813 is 8 with a remainder of 726.
The number 8 becomes the next digit in our result. 
Result so far: 37673.98
If we take 6504 away from 7230, we end up with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Let's proceed to step 11:
When dividing 7260 by 813, we get 8 with a remainder of 756.
Use 8 as the next digit of our solution. 
Result so far: 37673.988
If we subtract 6504 from 7260, we get 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

The final outcome is 37673.988, with a leftover of 0.0756.
