26146478 ÷ 921 
Let's see how many times 921 fits into 26146478.

Step 1:
921 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 921

Advancing to step 2:
If we divide 26 by 921, we get 0 and a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 921

Moving on to step 3:
If we divide 261 by 921, we get 0 and a remainder of 261.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 261 after subtracting 0 from 261.
Fetch the next digit (4) from the dividend, attach it to 261 and continue: 2614 / 921

Let's proceed to step 4:
921 can be fit into 2614 2 times, resulting in a remainder of 772.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1842 from 2614, we get 772.
Grab the next digit (6) from the dividend, add it to 772, then carry on: 7726 / 921

Let's proceed to step 5:
921 goes into 7726 8 times with a remainder of 358.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 7368 away from 7726, we end up with 358.
Bring next digit (4) of the dividend behind the 358 and repeat the process: 3584 / 921

Let's proceed to step 6:
921 goes into 3584 3 times with a remainder of 821.
Use 3 as the next digit of our solution. 
Result so far: 283.0
If we subtract 2763 from 3584, we get 821.
Fetch the next digit (7) from the dividend, attach it to 821 and continue: 8217 / 921

Moving on to step 7:
921 goes into 8217 8 times with a remainder of 849.
The next digit of our result is 8. 
Result so far: 2838.0
If we subtract 7368 from 8217, we get 849.
Append the next digit (8) from the dividend to 849 and continue with: 8498 / 921

Moving on to step 8:
When dividing 8498 by 921, we get 9 with a remainder of 209.
Use 9 as the next digit of our solution. 
Result so far: 28389.0
Subtracting 8289 from 8498 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 9:
2090 divided by 921 is 2 with a remainder of 248.
The next digit of our result is 2. 
Result so far: 28389.2
The remainder is 248 after subtracting 1842 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 10:
921 goes into 2480 2 times with a remainder of 638.
Record the quotient 2 as the next digit in the result. 
Result so far: 28389.22
Subtracting 1842 from 2480 leaves us with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

The final outcome is 28389.22, with a leftover of 0.638.
