We're dividing 21054678 by 263 
We're looking to find how many times 263 goes into 21054678.

Advancing to step 1:
When dividing 2 by 263, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 263

Step 2:
263 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 263

Step 3:
263 goes into 210 0 times with a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 210, we get 210.
Append the next digit (5) from the dividend to 210 and continue with: 2105 / 263

Advancing to step 4:
263 can be fit into 2105 8 times, resulting in a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 2104 away from 2105, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 263

Moving on to step 5:
If we divide 14 by 263, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 80.0
If we take 0 away from 14, we end up with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 263

Going ahead to step 6:
If we divide 146 by 263, we get 0 and a remainder of 146.
Write down 0 as next digit of the result. 
Result so far: 800.0
Subtracting 0 from 146 leaves us with 146.
Fetch the next digit (7) from the dividend, attach it to 146 and continue: 1467 / 263

Moving on to step 7:
If we divide 1467 by 263, we get 5 and a remainder of 152.
The next digit of our result is 5. 
Result so far: 8005.0
Subtract 1315 from 1467 to get 152.
Include the next digit (8) from the dividend after 152, then repeat: 1528 / 263

Advancing to step 8:
263 can be fit into 1528 5 times, resulting in a remainder of 213.
Write down 5 as next digit of the result. 
Result so far: 80055.0
Deduct 1315 from 1528 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Going ahead to step 9:
The number 263 fits into 2130 8 times, leaving a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 80055.8
If we subtract 2104 from 2130, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
263 goes into 260 0 times with a remainder of 260.
The next digit of our result is 0. 
Result so far: 80055.8
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 11:
263 can be fit into 2600 9 times, resulting in a remainder of 233.
Put 9 as the next digit of the answer. 
Result so far: 80055.809
Deduct 2367 from 2600 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 12:
263 goes into 2330 8 times with a remainder of 226.
The number 8 becomes the next digit in our result. 
Result so far: 80055.8098
Subtracting 2104 from 2330 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 13:
263 can be fit into 2260 8 times, resulting in a remainder of 156.
The next digit of our result is 8. 
Result so far: 80055.80988
Deduct 2104 from 2260 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The final result is 80055.80988 with a remainder of 0.000156.
