21455074 ÷ 223 
Our goal is to divide 21455074 by 223.

Moving on to step 1:
When dividing 2 by 223, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 223

On to step 2:
223 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 223

Step 3:
If we divide 214 by 223, we get 0 and a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 214 after subtracting 0 from 214.
Fetch the next digit (5) from the dividend, attach it to 214 and continue: 2145 / 223

On to step 4:
223 goes into 2145 9 times with a remainder of 138.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 2007 from 2145 and we're left with 138.
Fetch the next digit (5) from the dividend, attach it to 138 and continue: 1385 / 223

Step 5:
223 can be fit into 1385 6 times, resulting in a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtracting 1338 from 1385 leaves us with 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 223

On to step 6:
If we divide 470 by 223, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 962.0
Subtracting 446 from 470 leaves us with 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 223

On to step 7:
The number 223 fits into 247 1 times, leaving a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 9621.0
Subtracting 223 from 247 leaves us with 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 223

Advancing to step 8:
223 can be fit into 244 1 times, resulting in a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 96211.0
If we subtract 223 from 244, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
210 divided by 223 is 0 with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 96211.0
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
When dividing 2100 by 223, we get 9 with a remainder of 93.
The next digit of our result is 9. 
Result so far: 96211.09
Subtracting 2007 from 2100 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 11:
930 divided by 223 is 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 96211.094
Deduct 892 from 930 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
223 can be fit into 380 1 times, resulting in a remainder of 157.
The next digit of our result is 1. 
Result so far: 96211.0941
Deduct 223 from 380 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 13:
1570 divided by 223 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 96211.09417
Subtracting 1561 from 1570 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
223 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 96211.09417
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 15:
When dividing 900 by 223, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 96211.0941704
The remainder is 8 after subtracting 892 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 16:
223 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 96211.0941704
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 96211.0941704 and a remainder of 8e-08.
