We look at the division of 21930809 by 524 
We want to figure out the number of times 21930809 can be divided by 524.

Going ahead to step 1:
524 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 524

Moving on to step 2:
524 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 524

Going ahead to step 3:
If we divide 219 by 524, we get 0 and a remainder of 219.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 219, we get 219.
Include the next digit (3) from the dividend after 219, then repeat: 2193 / 524

Step 4:
If we divide 2193 by 524, we get 4 and a remainder of 97.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 2096 from 2193 and we're left with 97.
Fetch the next digit (0) from the dividend, attach it to 97 and continue: 970 / 524

Going ahead to step 5:
The number 524 fits into 970 1 times, leaving a remainder of 446.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 524 from 970 and we're left with 446.
Fetch the next digit (8) from the dividend, attach it to 446 and continue: 4468 / 524

Advancing to step 6:
If we divide 4468 by 524, we get 8 and a remainder of 276.
Write down 8 as next digit of the result. 
Result so far: 418.0
The remainder is 276 after subtracting 4192 from 4468.
Bring next digit (0) of the dividend behind the 276 and repeat the process: 2760 / 524

Step 7:
If we divide 2760 by 524, we get 5 and a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 4185.0
Deduct 2620 from 2760 and we're left with 140.
Bring next digit (9) of the dividend behind the 140 and repeat the process: 1409 / 524

Moving on to step 8:
524 can be fit into 1409 2 times, resulting in a remainder of 361.
The number 2 becomes the next digit in our result. 
Result so far: 41852.0
Subtracting 1048 from 1409 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 9:
524 goes into 3610 6 times with a remainder of 466.
The number 6 becomes the next digit in our result. 
Result so far: 41852.6
Subtracting 3144 from 3610 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 10:
4660 divided by 524 is 8 with a remainder of 468.
The number 8 becomes the next digit in our result. 
Result so far: 41852.68
If we take 4192 away from 4660, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 11:
4680 divided by 524 is 8 with a remainder of 488.
Use 8 as the next digit of our solution. 
Result so far: 41852.688
Subtract 4192 from 4680 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

In conclusion, the division gives 41852.688 with a balance of 0.0488.
