21402715 ÷ 224 
Our goal is to divide 21402715 by 224.

Going ahead to step 1:
When dividing 2 by 224, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 224

Moving on to step 2:
224 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 224

On to step 3:
If we divide 214 by 224, we get 0 and a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 214 to get 214.
Bring next digit (0) of the dividend behind the 214 and repeat the process: 2140 / 224

Advancing to step 4:
The number 224 fits into 2140 9 times, leaving a remainder of 124.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 2016 from 2140 leaves us with 124.
Bring next digit (2) of the dividend behind the 124 and repeat the process: 1242 / 224

Let's proceed to step 5:
224 can be fit into 1242 5 times, resulting in a remainder of 122.
The next digit of our result is 5. 
Result so far: 95.0
Subtracting 1120 from 1242 leaves us with 122.
Bring next digit (7) of the dividend behind the 122 and repeat the process: 1227 / 224

Step 6:
224 goes into 1227 5 times with a remainder of 107.
The number 5 becomes the next digit in our result. 
Result so far: 955.0
Subtract 1120 from 1227 to get 107.
Take the next digit (1) from the dividend and append it to 107, then repeat: 1071 / 224

Step 7:
224 goes into 1071 4 times with a remainder of 175.
Put 4 as the next digit of the answer. 
Result so far: 9554.0
Deduct 896 from 1071 and we're left with 175.
Bring next digit (5) of the dividend behind the 175 and repeat the process: 1755 / 224

On to step 8:
The number 224 fits into 1755 7 times, leaving a remainder of 187.
Record the quotient 7 as the next digit in the result. 
Result so far: 95547.0
Subtracting 1568 from 1755 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 9:
224 goes into 1870 8 times with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 95547.8
The remainder is 78 after subtracting 1792 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 10:
If we divide 780 by 224, we get 3 and a remainder of 108.
Use 3 as the next digit of our solution. 
Result so far: 95547.83
Subtract 672 from 780 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 11:
1080 divided by 224 is 4 with a remainder of 184.
The next digit of our result is 4. 
Result so far: 95547.834
If we take 896 away from 1080, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 12:
224 goes into 1840 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 95547.8348
The remainder is 48 after subtracting 1792 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
480 divided by 224 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 95547.83482
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
224 goes into 320 1 times with a remainder of 96.
The next digit of our result is 1. 
Result so far: 95547.834821
If we take 224 away from 320, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 15:
When dividing 960 by 224, we get 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 95547.8348214
Deduct 896 from 960 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 16:
640 divided by 224 is 2 with a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 95547.83482142
If we subtract 448 from 640, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

In conclusion, the division gives 95547.83482142 with a balance of 1.92e-07.
