21581 divided by 52 
We want to divide 21581 by 52.

Going ahead to step 1:
The number 52 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 52

Moving on to step 2:
52 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 52

Advancing to step 3:
215 divided by 52 is 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 208 from 215 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 52

Advancing to step 4:
The number 52 fits into 78 1 times, leaving a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 52 from 78 leaves us with 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 52

On to step 5:
The number 52 fits into 261 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 415.0
The remainder is 1 after subtracting 260 from 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
10 divided by 52 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 415.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
100 divided by 52 is 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 415.01
If we take 52 away from 100, we end up 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.

Step 8:
The number 52 fits into 480 9 times, leaving a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 415.019
If we subtract 468 from 480, we get 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 9:
120 divided by 52 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 415.0192
The remainder is 16 after subtracting 104 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
When dividing 160 by 52, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 415.01923
Deduct 156 from 160 and we're left 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.

Step 11:
52 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 415.01923
If we take 0 away from 40, we end up 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:
400 divided by 52 is 7 with a remainder of 36.
The next digit of our result is 7. 
Result so far: 415.0192307
If we take 364 away from 400, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
52 can be fit into 360 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 415.01923076
If we take 312 away from 360, we end up 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.

In conclusion, the division gives 415.01923076 with a balance of 4.8e-08.
