We're dividing 210509 by 63 
We want to figure out the number of times 210509 can be divided by 63.

On to step 1:
2 divided by 63 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 63

Let's proceed to step 2:
63 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 63

On to step 3:
63 can be fit into 210 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 189 from 210 to get 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 63

Step 4:
When dividing 215 by 63, we get 3 with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtract 189 from 215 to get 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 63

Advancing to step 5:
The number 63 fits into 260 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 334.0
Deduct 252 from 260 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 63

Moving on to step 6:
If we divide 89 by 63, we get 1 and a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 3341.0
The remainder is 26 after subtracting 63 from 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
If we divide 260 by 63, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 3341.4
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
80 divided by 63 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 3341.41
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
If we divide 170 by 63, we get 2 and a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 3341.412
If we subtract 126 from 170, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
440 divided by 63 is 6 with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 3341.4126
Subtracting 378 from 440 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
The number 63 fits into 620 9 times, leaving a remainder of 53.
The next digit of our result is 9. 
Result so far: 3341.41269
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 12:
63 goes into 530 8 times with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 3341.412698
Subtract 504 from 530 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
When dividing 260 by 63, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 3341.4126984
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
63 can be fit into 80 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 3341.41269841
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 3341.41269841, and the remainder is 1.7e-08.
