21011227 ÷ 921 
Let's see how many times 921 fits into 21011227.

On to step 1:
The number 921 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 921

Step 2:
921 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 921

Let's proceed to step 3:
921 goes into 210 0 times with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Fetch the next digit (1) from the dividend, attach it to 210 and continue: 2101 / 921

Moving on to step 4:
The number 921 fits into 2101 2 times, leaving a remainder of 259.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1842 from 2101 and we're left with 259.
Fetch the next digit (1) from the dividend, attach it to 259 and continue: 2591 / 921

Going ahead to step 5:
921 goes into 2591 2 times with a remainder of 749.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 749 after subtracting 1842 from 2591.
Fetch the next digit (2) from the dividend, attach it to 749 and continue: 7492 / 921

Step 6:
If we divide 7492 by 921, we get 8 and a remainder of 124.
The next digit of our result is 8. 
Result so far: 228.0
If we subtract 7368 from 7492, we get 124.
Bring next digit (2) of the dividend behind the 124 and repeat the process: 1242 / 921

Let's proceed to step 7:
When dividing 1242 by 921, we get 1 with a remainder of 321.
Put 1 as the next digit of the answer. 
Result so far: 2281.0
Deduct 921 from 1242 and we're left with 321.
Bring next digit (7) of the dividend behind the 321 and repeat the process: 3217 / 921

Let's proceed to step 8:
3217 divided by 921 is 3 with a remainder of 454.
The number 3 becomes the next digit in our result. 
Result so far: 22813.0
If we take 2763 away from 3217, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 9:
If we divide 4540 by 921, we get 4 and a remainder of 856.
Use 4 as the next digit of our solution. 
Result so far: 22813.4
If we take 3684 away from 4540, we end up with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Moving on to step 10:
921 can be fit into 8560 9 times, resulting in a remainder of 271.
Record the quotient 9 as the next digit in the result. 
Result so far: 22813.49
Deduct 8289 from 8560 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 11:
If we divide 2710 by 921, we get 2 and a remainder of 868.
Write down 2 as next digit of the result. 
Result so far: 22813.492
Subtract 1842 from 2710 to get 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

On to step 12:
921 goes into 8680 9 times with a remainder of 391.
The next digit of our result is 9. 
Result so far: 22813.4929
Subtract 8289 from 8680 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Step 13:
921 can be fit into 3910 4 times, resulting in a remainder of 226.
The number 4 becomes the next digit in our result. 
Result so far: 22813.49294
If we take 3684 away from 3910, we end up 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.

On to step 14:
921 can be fit into 2260 2 times, resulting in a remainder of 418.
Write down 2 as next digit of the result. 
Result so far: 22813.492942
Deduct 1842 from 2260 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 15:
The number 921 fits into 4180 4 times, leaving a remainder of 496.
Put 4 as the next digit of the answer. 
Result so far: 22813.4929424
Subtract 3684 from 4180 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 16:
921 goes into 4960 5 times with a remainder of 355.
The next digit of our result is 5. 
Result so far: 22813.49294245
The remainder is 355 after subtracting 4605 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

In conclusion, the division gives 22813.49294245 with a balance of 3.55e-07.
