We divide 21216462 by 538
Let's see how many times 538 fits into 21216462.

On to step 1:
If we divide 2 by 538, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 538

Step 2:
538 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 538

Moving on to step 3:
212 divided by 538 is 0 with a remainder of 212.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Bring next digit (1) of the dividend behind the 212 and repeat the process: 2121 / 538

Let's proceed to step 4:
538 goes into 2121 3 times with a remainder of 507.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 507 after subtracting 1614 from 2121.
Append the next digit (6) from the dividend to 507 and continue with: 5076 / 538

On to step 5:
538 can be fit into 5076 9 times, resulting in a remainder of 234.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtracting 4842 from 5076 leaves us with 234.
Include the next digit (4) from the dividend after 234, then repeat: 2344 / 538

Going ahead to step 6:
538 goes into 2344 4 times with a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 394.0
Subtracting 2152 from 2344 leaves us with 192.
Append the next digit (6) from the dividend to 192 and continue with: 1926 / 538

Going ahead to step 7:
1926 divided by 538 is 3 with a remainder of 312.
Write down 3 as next digit of the result. 
Result so far: 3943.0
If we take 1614 away from 1926, we end up with 312.
Include the next digit (2) from the dividend after 312, then repeat: 3122 / 538

On to step 8:
When dividing 3122 by 538, we get 5 with a remainder of 432.
The next digit of our result is 5. 
Result so far: 39435.0
Subtracting 2690 from 3122 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 9:
4320 divided by 538 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 39435.8
The remainder is 16 after subtracting 4304 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
160 divided by 538 is 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 39435.8
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 11:
If we divide 1600 by 538, we get 2 and a remainder of 524.
Record the quotient 2 as the next digit in the result. 
Result so far: 39435.802
Subtract 1076 from 1600 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 12:
When dividing 5240 by 538, we get 9 with a remainder of 398.
The next digit of our result is 9. 
Result so far: 39435.8029
Subtract 4842 from 5240 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 13:
538 goes into 3980 7 times with a remainder of 214.
Put 7 as the next digit of the answer. 
Result so far: 39435.80297
Subtract 3766 from 3980 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 14:
If we divide 2140 by 538, we get 3 and a remainder of 526.
The number 3 becomes the next digit in our result. 
Result so far: 39435.802973
Subtracting 1614 from 2140 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Going ahead to step 15:
When dividing 5260 by 538, we get 9 with a remainder of 418.
Write down 9 as next digit of the result. 
Result so far: 39435.8029739
The remainder is 418 after subtracting 4842 from 5260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 16:
The number 538 fits into 4180 7 times, leaving a remainder of 414.
Write down 7 as next digit of the result. 
Result so far: 39435.80297397
If we take 3766 away from 4180, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The final result is 39435.80297397 with a remainder of 4.14e-07.
