We divide 20815432 by 63
We want to figure out the number of times 20815432 can be divided by 63.

Step 1:
When dividing 2 by 63, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 63

Going ahead to step 2:
63 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 63

Moving on to step 3:
If we divide 208 by 63, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 189 from 208 leaves us with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 63

Going ahead to step 4:
63 can be fit into 191 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtract 189 from 191 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 63

Going ahead to step 5:
If we divide 25 by 63, we get 0 and a remainder of 25.
The next digit of our result is 0. 
Result so far: 330.0
Subtracting 0 from 25 leaves us with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 63

Advancing to step 6:
The number 63 fits into 254 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 3304.0
Subtracting 252 from 254 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 63

Step 7:
If we divide 23 by 63, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 33040.0
Subtracting 0 from 23 leaves us with 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 63

On to step 8:
232 divided by 63 is 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 330403.0
If we take 189 away from 232, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
When dividing 430 by 63, we get 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 330403.6
The remainder is 52 after subtracting 378 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
When dividing 520 by 63, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 330403.68
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
If we divide 160 by 63, we get 2 and a remainder of 34.
The next digit of our result is 2. 
Result so far: 330403.682
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
63 can be fit into 340 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 330403.6825
Subtracting 315 from 340 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
If we divide 250 by 63, we get 3 and a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 330403.68253
Subtracting 189 from 250 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 14:
If we divide 610 by 63, we get 9 and a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 330403.682539
Subtract 567 from 610 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 15:
If we divide 430 by 63, we get 6 and a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 330403.6825396
Deduct 378 from 430 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 16:
63 goes into 520 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 330403.68253968
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 330403.68253968, with a leftover of 1.6e-08.
