We look at the division of 21273447 by 63 
We want to figure out the number of times 21273447 can be divided by 63.

On to step 1:
63 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 63

Going ahead to step 2:
63 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 63

Advancing to step 3:
63 goes into 212 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 23 after subtracting 189 from 212.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 63

Let's proceed to step 4:
If we divide 237 by 63, we get 3 and a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we subtract 189 from 237, we get 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 63

Advancing to step 5:
483 divided by 63 is 7 with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 337.0
Subtracting 441 from 483 leaves us with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 63

Let's proceed to step 6:
63 can be fit into 424 6 times, resulting in a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 3376.0
Subtract 378 from 424 to get 46.
Grab the next digit (4) from the dividend, add it to 46, then carry on: 464 / 63

Going ahead to step 7:
63 goes into 464 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 33767.0
If we take 441 away from 464, we end up with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 63

Going ahead to step 8:
63 can be fit into 237 3 times, resulting in a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 337673.0
Deduct 189 from 237 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
480 divided by 63 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 337673.7
Subtract 441 from 480 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 10:
When dividing 390 by 63, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 337673.76
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
If we divide 120 by 63, we get 1 and a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 337673.761
Deduct 63 from 120 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 12:
The number 63 fits into 570 9 times, leaving a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 337673.7619
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
63 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 337673.7619
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
When dividing 300 by 63, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 337673.761904
The remainder is 48 after subtracting 252 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 15:
The number 63 fits into 480 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 337673.7619047
The remainder is 39 after subtracting 441 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 16:
63 goes into 390 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 337673.76190476
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 337673.76190476 with a remaining 1.2e-08.
