We divide 21897907 by 815
We're looking to find how many times 815 goes into 21897907.

On to step 1:
815 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 815

Step 2:
The number 815 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 815

Let's proceed to step 3:
815 can be fit into 218 0 times, resulting in a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 218 to get 218.
Grab the next digit (9) from the dividend, add it to 218, then carry on: 2189 / 815

Moving on to step 4:
The number 815 fits into 2189 2 times, leaving a remainder of 559.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1630 from 2189 to get 559.
Append the next digit (7) from the dividend to 559 and continue with: 5597 / 815

Advancing to step 5:
The number 815 fits into 5597 6 times, leaving a remainder of 707.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtracting 4890 from 5597 leaves us with 707.
Fetch the next digit (9) from the dividend, attach it to 707 and continue: 7079 / 815

Going ahead to step 6:
7079 divided by 815 is 8 with a remainder of 559.
Write down 8 as next digit of the result. 
Result so far: 268.0
Deduct 6520 from 7079 and we're left with 559.
Grab the next digit (0) from the dividend, add it to 559, then carry on: 5590 / 815

Advancing to step 7:
If we divide 5590 by 815, we get 6 and a remainder of 700.
The number 6 becomes the next digit in our result. 
Result so far: 2686.0
If we take 4890 away from 5590, we end up with 700.
Include the next digit (7) from the dividend after 700, then repeat: 7007 / 815

Going ahead to step 8:
When dividing 7007 by 815, we get 8 with a remainder of 487.
Record the quotient 8 as the next digit in the result. 
Result so far: 26868.0
Subtracting 6520 from 7007 leaves us with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Step 9:
815 can be fit into 4870 5 times, resulting in a remainder of 795.
The number 5 becomes the next digit in our result. 
Result so far: 26868.5
Deduct 4075 from 4870 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.

Going ahead to step 10:
When dividing 7950 by 815, we get 9 with a remainder of 615.
Record the quotient 9 as the next digit in the result. 
Result so far: 26868.59
If we take 7335 away from 7950, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Moving on to step 11:
815 can be fit into 6150 7 times, resulting in a remainder of 445.
The next digit of our result is 7. 
Result so far: 26868.597
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.

Going ahead to step 12:
When dividing 4450 by 815, we get 5 with a remainder of 375.
The next digit of our result is 5. 
Result so far: 26868.5975
Subtracting 4075 from 4450 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 13:
815 can be fit into 3750 4 times, resulting in a remainder of 490.
Write down 4 as next digit of the result. 
Result so far: 26868.59754
If we subtract 3260 from 3750, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 14:
815 goes into 4900 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 26868.597546
If we take 4890 away from 4900, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 15:
If we divide 100 by 815, we get 0 and a remainder of 100.
The next digit of our result is 0. 
Result so far: 26868.597546
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 16:
1000 divided by 815 is 1 with a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 26868.59754601
The remainder is 185 after subtracting 815 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

The final result is 26868.59754601 with a remainder of 1.85e-07.
