We look at the division of 21203150 by 447 
We want to figure out the number of times 21203150 can be divided by 447.

Step 1:
When dividing 2 by 447, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 447

Moving on to step 2:
If we divide 21 by 447, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 447

Moving on to step 3:
447 goes into 212 0 times with a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 212 and we're left with 212.
Append the next digit (0) from the dividend to 212 and continue with: 2120 / 447

Let's proceed to step 4:
447 can be fit into 2120 4 times, resulting in a remainder of 332.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 1788 from 2120 to get 332.
Grab the next digit (3) from the dividend, add it to 332, then carry on: 3323 / 447

Moving on to step 5:
When dividing 3323 by 447, we get 7 with a remainder of 194.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 3129 away from 3323, we end up with 194.
Fetch the next digit (1) from the dividend, attach it to 194 and continue: 1941 / 447

Let's proceed to step 6:
447 can be fit into 1941 4 times, resulting in a remainder of 153.
Write down 4 as next digit of the result. 
Result so far: 474.0
Deduct 1788 from 1941 and we're left with 153.
Fetch the next digit (5) from the dividend, attach it to 153 and continue: 1535 / 447

Moving on to step 7:
447 goes into 1535 3 times with a remainder of 194.
The next digit of our result is 3. 
Result so far: 4743.0
Subtracting 1341 from 1535 leaves us with 194.
Grab the next digit (0) from the dividend, add it to 194, then carry on: 1940 / 447

Moving on to step 8:
When dividing 1940 by 447, we get 4 with a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 47434.0
Subtracting 1788 from 1940 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 9:
If we divide 1520 by 447, we get 3 and a remainder of 179.
Use 3 as the next digit of our solution. 
Result so far: 47434.3
If we take 1341 away from 1520, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 10:
447 goes into 1790 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 47434.34
Subtracting 1788 from 1790 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
447 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 47434.34
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
447 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 47434.34
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 47434.34, and the remainder is 0.002.
