219538 divided by 21 
We want to figure out the number of times 219538 can be divided by 21.

Let's proceed to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 21

Let's proceed to step 2:
The number 21 fits into 21 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 21 away from 21, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 21

Going ahead to step 3:
If we divide 9 by 21, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 21

Step 4:
The number 21 fits into 95 4 times, leaving a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtract 84 from 95 to get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 21

Going ahead to step 5:
If we divide 113 by 21, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 1045.0
If we subtract 105 from 113, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 21

Moving on to step 6:
If we divide 88 by 21, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 10454.0
Subtract 84 from 88 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
21 goes into 40 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 10454.1
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
21 goes into 190 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 10454.19
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
21 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 10454.19
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
21 can be fit into 100 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 10454.1904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 10454.19047
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
130 divided by 21 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 10454.190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
If we divide 40 by 21, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 10454.1904761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
If we divide 190 by 21, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 10454.19047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 10454.19047619 with a balance of 1e-09.
