21904017 ÷ 894 
Let's see how many times 894 fits into 21904017.

Let's proceed to step 1:
894 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 894

On to step 2:
If we divide 21 by 894, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 894

Moving on to step 3:
894 goes into 219 0 times with a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 219 and we're left with 219.
Bring next digit (0) of the dividend behind the 219 and repeat the process: 2190 / 894

Going ahead to step 4:
When dividing 2190 by 894, we get 2 with a remainder of 402.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1788 from 2190 and we're left with 402.
Append the next digit (4) from the dividend to 402 and continue with: 4024 / 894

Let's proceed to step 5:
4024 divided by 894 is 4 with a remainder of 448.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 448 after subtracting 3576 from 4024.
Include the next digit (0) from the dividend after 448, then repeat: 4480 / 894

Step 6:
894 goes into 4480 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 245.0
Deduct 4470 from 4480 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 894

Let's proceed to step 7:
When dividing 101 by 894, we get 0 with a remainder of 101.
Put 0 as the next digit of the answer. 
Result so far: 2450.0
If we take 0 away from 101, we end up with 101.
Fetch the next digit (7) from the dividend, attach it to 101 and continue: 1017 / 894

Going ahead to step 8:
The number 894 fits into 1017 1 times, leaving a remainder of 123.
Use 1 as the next digit of our solution. 
Result so far: 24501.0
If we subtract 894 from 1017, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
894 goes into 1230 1 times with a remainder of 336.
The number 1 becomes the next digit in our result. 
Result so far: 24501.1
Subtracting 894 from 1230 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 10:
894 goes into 3360 3 times with a remainder of 678.
Record the quotient 3 as the next digit in the result. 
Result so far: 24501.13
Subtract 2682 from 3360 to get 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

On to step 11:
If we divide 6780 by 894, we get 7 and a remainder of 522.
The number 7 becomes the next digit in our result. 
Result so far: 24501.137
The remainder is 522 after subtracting 6258 from 6780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Moving on to step 12:
894 can be fit into 5220 5 times, resulting in a remainder of 750.
Use 5 as the next digit of our solution. 
Result so far: 24501.1375
If we take 4470 away from 5220, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 13:
894 goes into 7500 8 times with a remainder of 348.
The next digit of our result is 8. 
Result so far: 24501.13758
If we take 7152 away from 7500, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 14:
The number 894 fits into 3480 3 times, leaving a remainder of 798.
Write down 3 as next digit of the result. 
Result so far: 24501.137583
If we subtract 2682 from 3480, we get 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Moving on to step 15:
7980 divided by 894 is 8 with a remainder of 828.
Use 8 as the next digit of our solution. 
Result so far: 24501.1375838
If we take 7152 away from 7980, we end up with 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Let's proceed to step 16:
If we divide 8280 by 894, we get 9 and a remainder of 234.
Put 9 as the next digit of the answer. 
Result so far: 24501.13758389
If we take 8046 away from 8280, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The final outcome is 24501.13758389, with a leftover of 2.34e-07.
