The remainder is 21 after subtracting 0 from 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 889

On to step 3:
When dividing 211 by 889, we get 0 with a remainder of 211.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 211 and we're left with 211.
Include the next digit (2) from the dividend after 211, then repeat: 2112 / 889

Step 4:
If we divide 2112 by 889, we get 2 and a remainder of 334.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1778 from 2112 to get 334.
Include the next digit (9) from the dividend after 334, then repeat: 3349 / 889

Step 5:
889 can be fit into 3349 3 times, resulting in a remainder of 682.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 2667 from 3349 and we're left with 682.
Append the next digit (4) from the dividend to 682 and continue with: 6824 / 889

Step 6:
889 can be fit into 6824 7 times, resulting in a remainder of 601.
Record the quotient 7 as the next digit in the result. 
Result so far: 237.0
If we take 6223 away from 6824, we end up with 601.
Append the next digit (1) from the dividend to 601 and continue with: 6011 / 889

Let's proceed to step 7:
If we divide 6011 by 889, we get 6 and a remainder of 677.
The next digit of our result is 6. 
Result so far: 2376.0
Subtracting 5334 from 6011 leaves us with 677.
Append the next digit (8) from the dividend to 677 and continue with: 6778 / 889

Step 8:
When dividing 6778 by 889, we get 7 with a remainder of 555.
Write down 7 as next digit of the result. 
Result so far: 23767.0
Subtracting 6223 from 6778 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 9:
The number 889 fits into 5550 6 times, leaving a remainder of 216.
Write down 6 as next digit of the result. 
Result so far: 23767.6
Subtract 5334 from 5550 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 10:
If we divide 2160 by 889, we get 2 and a remainder of 382.
Write down 2 as next digit of the result. 
Result so far: 23767.62
Deduct 1778 from 2160 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 11:
If we divide 3820 by 889, we get 4 and a remainder of 264.
Use 4 as the next digit of our solution. 
Result so far: 23767.624
Subtracting 3556 from 3820 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 12:
2640 divided by 889 is 2 with a remainder of 862.
Put 2 as the next digit of the answer. 
Result so far: 23767.6242
Subtract 1778 from 2640 to get 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

Going ahead to step 13:
The number 889 fits into 8620 9 times, leaving a remainder of 619.
Write down 9 as next digit of the result. 
Result so far: 23767.62429
The remainder is 619 after subtracting 8001 from 8620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Advancing to step 14:
If we divide 6190 by 889, we get 6 and a remainder of 856.
Use 6 as the next digit of our solution. 
Result so far: 23767.624296
Subtract 5334 from 6190 to get 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Advancing to step 15:
8560 divided by 889 is 9 with a remainder of 559.
Record the quotient 9 as the next digit in the result. 
Result so far: 23767.6242969
Deduct 8001 from 8560 and we're left with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Going ahead to step 16:
If we divide 5590 by 889, we get 6 and a remainder of 256.
The next digit of our result is 6. 
Result so far: 23767.62429696
The remainder is 256 after subtracting 5334 from 5590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final result is 23767.62429696 with a remainder of 2.56e-07.
