We look at the division of 21110380 by 52 
Let's see how many times 52 fits into 21110380.

Going ahead to step 1:
52 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 52

Advancing to step 2:
21 divided by 52 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 52

Let's proceed to step 3:
If we divide 211 by 52, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 3 after subtracting 208 from 211.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 52

Moving on to step 4:
52 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 31 to get 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 52

Going ahead to step 5:
52 goes into 310 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 405.0
Subtracting 260 from 310 leaves us with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 52

Going ahead to step 6:
52 can be fit into 503 9 times, resulting in a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 4059.0
If we subtract 468 from 503, we get 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 52

Step 7:
If we divide 358 by 52, we get 6 and a remainder of 46.
The next digit of our result is 6. 
Result so far: 40596.0
Deduct 312 from 358 and we're left with 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 52

On to step 8:
If we divide 460 by 52, we get 8 and a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 405968.0
Deduct 416 from 460 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
440 divided by 52 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 405968.8
If we subtract 416 from 440, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
If we divide 240 by 52, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 405968.84
Subtracting 208 from 240 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
When dividing 320 by 52, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 405968.846
Deduct 312 from 320 and we're left 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.

Moving on to step 12:
52 goes into 80 1 times with a remainder of 28.
The next digit of our result is 1. 
Result so far: 405968.8461
Subtracting 52 from 80 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
The number 52 fits into 280 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 405968.84615
Subtract 260 from 280 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
52 can be fit into 200 3 times, resulting in a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 405968.846153
If we subtract 156 from 200, 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 15:
The number 52 fits into 440 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 405968.8461538
If we subtract 416 from 440, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 16:
When dividing 240 by 52, we get 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 405968.84615384
Subtracting 208 from 240 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 405968.84615384 with a remainder of 3.2e-08.
