Let's divide 34499821 by 815
We want to figure out the number of times 34499821 can be divided by 815.

Advancing to step 1:
If we divide 3 by 815, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 815

Advancing to step 2:
815 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 815

Step 3:
344 divided by 815 is 0 with a remainder of 344.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 344 and we're left with 344.
Take the next digit (9) from the dividend and append it to 344, then repeat: 3449 / 815

Moving on to step 4:
815 goes into 3449 4 times with a remainder of 189.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 3260 from 3449 to get 189.
Fetch the next digit (9) from the dividend, attach it to 189 and continue: 1899 / 815

Moving on to step 5:
If we divide 1899 by 815, we get 2 and a remainder of 269.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtract 1630 from 1899 to get 269.
Include the next digit (8) from the dividend after 269, then repeat: 2698 / 815

Moving on to step 6:
If we divide 2698 by 815, we get 3 and a remainder of 253.
Write down 3 as next digit of the result. 
Result so far: 423.0
The remainder is 253 after subtracting 2445 from 2698.
Bring next digit (2) of the dividend behind the 253 and repeat the process: 2532 / 815

Moving on to step 7:
815 can be fit into 2532 3 times, resulting in a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 4233.0
The remainder is 87 after subtracting 2445 from 2532.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 815

Going ahead to step 8:
When dividing 871 by 815, we get 1 with a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 42331.0
If we take 815 away from 871, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
815 goes into 560 0 times with a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 42331.0
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 10:
815 goes into 5600 6 times with a remainder of 710.
Write down 6 as next digit of the result. 
Result so far: 42331.06
Subtract 4890 from 5600 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Let's proceed to step 11:
The number 815 fits into 7100 8 times, leaving a remainder of 580.
Use 8 as the next digit of our solution. 
Result so far: 42331.068
Subtracting 6520 from 7100 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 12:
When dividing 5800 by 815, we get 7 with a remainder of 95.
The next digit of our result is 7. 
Result so far: 42331.0687
Subtract 5705 from 5800 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 13:
815 can be fit into 950 1 times, resulting in a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 42331.06871
If we subtract 815 from 950, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 14:
815 can be fit into 1350 1 times, resulting in a remainder of 535.
Write down 1 as next digit of the result. 
Result so far: 42331.068711
Subtracting 815 from 1350 leaves us with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Our division results in 42331.068711 with a remaining 5.35e-05.
