We look at the division of 42628452 by 815 
We're looking to find how many times 815 goes into 42628452.

On to step 1:
The number 815 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 815

On to step 2:
If we divide 42 by 815, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 815

Going ahead to step 3:
815 can be fit into 426 0 times, resulting in a remainder of 426.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 426 and we're left with 426.
Include the next digit (2) from the dividend after 426, then repeat: 4262 / 815

Advancing to step 4:
815 goes into 4262 5 times with a remainder of 187.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 4075 away from 4262, we end up with 187.
Bring next digit (8) of the dividend behind the 187 and repeat the process: 1878 / 815

Going ahead to step 5:
815 goes into 1878 2 times with a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we subtract 1630 from 1878, we get 248.
Take the next digit (4) from the dividend and append it to 248, then repeat: 2484 / 815

On to step 6:
When dividing 2484 by 815, we get 3 with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 523.0
Subtracting 2445 from 2484 leaves us with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 815

Step 7:
815 goes into 395 0 times with a remainder of 395.
Record the quotient 0 as the next digit in the result. 
Result so far: 5230.0
The remainder is 395 after subtracting 0 from 395.
Include the next digit (2) from the dividend after 395, then repeat: 3952 / 815

Let's proceed to step 8:
815 can be fit into 3952 4 times, resulting in a remainder of 692.
Put 4 as the next digit of the answer. 
Result so far: 52304.0
Subtracting 3260 from 3952 leaves us with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Let's proceed to step 9:
815 can be fit into 6920 8 times, resulting in a remainder of 400.
Record the quotient 8 as the next digit in the result. 
Result so far: 52304.8
Subtract 6520 from 6920 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 10:
815 goes into 4000 4 times with a remainder of 740.
Record the quotient 4 as the next digit in the result. 
Result so far: 52304.84
If we take 3260 away from 4000, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 11:
7400 divided by 815 is 9 with a remainder of 65.
The next digit of our result is 9. 
Result so far: 52304.849
Deduct 7335 from 7400 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
815 can be fit into 650 0 times, resulting in a remainder of 650.
Write down 0 as next digit of the result. 
Result so far: 52304.849
Subtract 0 from 650 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 13:
6500 divided by 815 is 7 with a remainder of 795.
The number 7 becomes the next digit in our result. 
Result so far: 52304.84907
Deduct 5705 from 6500 and we're left with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Let's proceed to step 14:
When dividing 7950 by 815, we get 9 with a remainder of 615.
Use 9 as the next digit of our solution. 
Result so far: 52304.849079
Subtract 7335 from 7950 to get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Step 15:
The number 815 fits into 6150 7 times, leaving a remainder of 445.
Put 7 as the next digit of the answer. 
Result so far: 52304.8490797
Deduct 5705 from 6150 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 16:
When dividing 4450 by 815, we get 5 with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 52304.84907975
If we subtract 4075 from 4450, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Our division results in 52304.84907975 with a remaining 3.75e-07.
