We're dividing 21563120 by 53 
Let's see how many times 53 fits into 21563120.

Going ahead to step 1:
53 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
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 53

Advancing to step 2:
53 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 53

Advancing to step 3:
53 goes into 215 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 212 from 215 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 53

On to step 4:
53 goes into 36 0 times with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 36, we end up with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 53

Going ahead to step 5:
If we divide 363 by 53, we get 6 and a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 406.0
Subtract 318 from 363 to get 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 53

Let's proceed to step 6:
If we divide 451 by 53, we get 8 and a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 4068.0
Subtracting 424 from 451 leaves us with 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 53

Advancing to step 7:
272 divided by 53 is 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 40685.0
If we subtract 265 from 272, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 53

Let's proceed to step 8:
53 goes into 70 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 406851.0
If we take 53 away from 70, we end up 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.

On to step 9:
53 can be fit into 170 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 406851.3
Subtracting 159 from 170 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
The number 53 fits into 110 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 406851.32
Subtracting 106 from 110 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
53 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 406851.32
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
53 goes into 400 7 times with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 406851.3207
If we take 371 away from 400, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
When dividing 290 by 53, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 406851.32075
If we take 265 away from 290, we end up 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 14:
The number 53 fits into 250 4 times, leaving a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 406851.320754
If we subtract 212 from 250, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 15:
If we divide 380 by 53, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 406851.3207547
Subtract 371 from 380 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 16:
If we divide 90 by 53, we get 1 and a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 406851.32075471
If we subtract 53 from 90, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 406851.32075471 with a remaining 3.7e-08.
