Let's divide 21645790 by 447
Let's see how many times 447 fits into 21645790.

On to step 1:
When dividing 2 by 447, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 447

Going ahead to step 2:
If we divide 21 by 447, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 447

On to step 3:
If we divide 216 by 447, we get 0 and a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 216 after subtracting 0 from 216.
Grab the next digit (4) from the dividend, add it to 216, then carry on: 2164 / 447

Step 4:
If we divide 2164 by 447, we get 4 and a remainder of 376.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 376 after subtracting 1788 from 2164.
Bring next digit (5) of the dividend behind the 376 and repeat the process: 3765 / 447

Let's proceed to step 5:
If we divide 3765 by 447, we get 8 and a remainder of 189.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 3576 away from 3765, we end up with 189.
Bring next digit (7) of the dividend behind the 189 and repeat the process: 1897 / 447

Step 6:
When dividing 1897 by 447, we get 4 with a remainder of 109.
Put 4 as the next digit of the answer. 
Result so far: 484.0
Subtracting 1788 from 1897 leaves us with 109.
Fetch the next digit (9) from the dividend, attach it to 109 and continue: 1099 / 447

Let's proceed to step 7:
447 can be fit into 1099 2 times, resulting in a remainder of 205.
The next digit of our result is 2. 
Result so far: 4842.0
Subtracting 894 from 1099 leaves us with 205.
Include the next digit (0) from the dividend after 205, then repeat: 2050 / 447

Going ahead to step 8:
If we divide 2050 by 447, we get 4 and a remainder of 262.
Write down 4 as next digit of the result. 
Result so far: 48424.0
The remainder is 262 after subtracting 1788 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 9:
If we divide 2620 by 447, we get 5 and a remainder of 385.
The next digit of our result is 5. 
Result so far: 48424.5
If we take 2235 away from 2620, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 10:
If we divide 3850 by 447, we get 8 and a remainder of 274.
The number 8 becomes the next digit in our result. 
Result so far: 48424.58
The remainder is 274 after subtracting 3576 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 11:
When dividing 2740 by 447, we get 6 with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 48424.586
Deduct 2682 from 2740 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
When dividing 580 by 447, we get 1 with a remainder of 133.
Record the quotient 1 as the next digit in the result. 
Result so far: 48424.5861
The remainder is 133 after subtracting 447 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 13:
447 can be fit into 1330 2 times, resulting in a remainder of 436.
Use 2 as the next digit of our solution. 
Result so far: 48424.58612
If we take 894 away from 1330, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 14:
447 goes into 4360 9 times with a remainder of 337.
The number 9 becomes the next digit in our result. 
Result so far: 48424.586129
If we take 4023 away from 4360, we end up with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 15:
3370 divided by 447 is 7 with a remainder of 241.
Use 7 as the next digit of our solution. 
Result so far: 48424.5861297
Subtract 3129 from 3370 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Advancing to step 16:
447 can be fit into 2410 5 times, resulting in a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 48424.58612975
The remainder is 175 after subtracting 2235 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

In conclusion, the division gives 48424.58612975 with a balance of 1.75e-07.
