We divide 28603013 by 813
We want to figure out the number of times 28603013 can be divided by 813.

On to step 1:
2 divided by 813 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 813

Advancing to step 2:
28 divided by 813 is 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 813

Going ahead to step 3:
286 divided by 813 is 0 with a remainder of 286.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 286, we get 286.
Grab the next digit (0) from the dividend, add it to 286, then carry on: 2860 / 813

Let's proceed to step 4:
813 can be fit into 2860 3 times, resulting in a remainder of 421.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2439 from 2860 to get 421.
Grab the next digit (3) from the dividend, add it to 421, then carry on: 4213 / 813

Let's proceed to step 5:
The number 813 fits into 4213 5 times, leaving a remainder of 148.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Deduct 4065 from 4213 and we're left with 148.
Append the next digit (0) from the dividend to 148 and continue with: 1480 / 813

On to step 6:
1480 divided by 813 is 1 with a remainder of 667.
Use 1 as the next digit of our solution. 
Result so far: 351.0
Subtracting 813 from 1480 leaves us with 667.
Take the next digit (1) from the dividend and append it to 667, then repeat: 6671 / 813

Going ahead to step 7:
If we divide 6671 by 813, we get 8 and a remainder of 167.
Put 8 as the next digit of the answer. 
Result so far: 3518.0
Deduct 6504 from 6671 and we're left with 167.
Append the next digit (3) from the dividend to 167 and continue with: 1673 / 813

On to step 8:
813 can be fit into 1673 2 times, resulting in a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 35182.0
If we take 1626 away from 1673, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 9:
813 can be fit into 470 0 times, resulting in a remainder of 470.
The next digit of our result is 0. 
Result so far: 35182.0
The remainder is 470 after subtracting 0 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 10:
If we divide 4700 by 813, we get 5 and a remainder of 635.
Record the quotient 5 as the next digit in the result. 
Result so far: 35182.05
If we take 4065 away from 4700, we end up with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Let's proceed to step 11:
813 can be fit into 6350 7 times, resulting in a remainder of 659.
The number 7 becomes the next digit in our result. 
Result so far: 35182.057
Subtract 5691 from 6350 to get 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Moving on to step 12:
When dividing 6590 by 813, we get 8 with a remainder of 86.
Write down 8 as next digit of the result. 
Result so far: 35182.0578
Subtract 6504 from 6590 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 13:
When dividing 860 by 813, we get 1 with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 35182.05781
Subtracting 813 from 860 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 14:
470 divided by 813 is 0 with a remainder of 470.
Use 0 as the next digit of our solution. 
Result so far: 35182.05781
If we subtract 0 from 470, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 15:
813 goes into 4700 5 times with a remainder of 635.
The number 5 becomes the next digit in our result. 
Result so far: 35182.0578105
If we subtract 4065 from 4700, we get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Step 16:
When dividing 6350 by 813, we get 7 with a remainder of 659.
Record the quotient 7 as the next digit in the result. 
Result so far: 35182.05781057
Deduct 5691 from 6350 and we're left with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

After the division, we end up with 35182.05781057 and a remainder of 6.59e-07.
