Advancing to step 4:
2178 divided by 827 is 2 with a remainder of 524.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1654 away from 2178, we end up with 524.
Grab the next digit (7) from the dividend, add it to 524, then carry on: 5247 / 827

Advancing to step 5:
When dividing 5247 by 827, we get 6 with a remainder of 285.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we subtract 4962 from 5247, we get 285.
Fetch the next digit (9) from the dividend, attach it to 285 and continue: 2859 / 827

Moving on to step 6:
2859 divided by 827 is 3 with a remainder of 378.
Write down 3 as next digit of the result. 
Result so far: 263.0
Deduct 2481 from 2859 and we're left with 378.
Append the next digit (4) from the dividend to 378 and continue with: 3784 / 827

Let's proceed to step 7:
The number 827 fits into 3784 4 times, leaving a remainder of 476.
The next digit of our result is 4. 
Result so far: 2634.0
If we take 3308 away from 3784, we end up with 476.
Bring next digit (7) of the dividend behind the 476 and repeat the process: 4767 / 827

Going ahead to step 8:
If we divide 4767 by 827, we get 5 and a remainder of 632.
Use 5 as the next digit of our solution. 
Result so far: 26345.0
Subtract 4135 from 4767 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 9:
If we divide 6320 by 827, we get 7 and a remainder of 531.
Record the quotient 7 as the next digit in the result. 
Result so far: 26345.7
The remainder is 531 after subtracting 5789 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Step 10:
827 goes into 5310 6 times with a remainder of 348.
The number 6 becomes the next digit in our result. 
Result so far: 26345.76
If we take 4962 away from 5310, 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.

Let's proceed to step 11:
The number 827 fits into 3480 4 times, leaving a remainder of 172.
Write down 4 as next digit of the result. 
Result so far: 26345.764
Subtract 3308 from 3480 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 12:
When dividing 1720 by 827, we get 2 with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 26345.7642
Subtracting 1654 from 1720 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
If we divide 660 by 827, we get 0 and a remainder of 660.
Record the quotient 0 as the next digit in the result. 
Result so far: 26345.7642
Subtracting 0 from 660 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 14:
827 goes into 6600 7 times with a remainder of 811.
Put 7 as the next digit of the answer. 
Result so far: 26345.764207
Deduct 5789 from 6600 and we're left with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Moving on to step 15:
The number 827 fits into 8110 9 times, leaving a remainder of 667.
The next digit of our result is 9. 
Result so far: 26345.7642079
Subtract 7443 from 8110 to get 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Let's proceed to step 16:
If we divide 6670 by 827, we get 8 and a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 26345.76420798
Deduct 6616 from 6670 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 26345.76420798 with a balance of 5.4e-08.
