We divide 534602 by 21
Let's see how many times 21 fits into 534602.

Let's proceed to step 1:
If we divide 5 by 21, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 21

Going ahead to step 2:
21 can be fit into 53 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 42 from 53 leaves us with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 21

On to step 3:
21 goes into 114 5 times with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 105 from 114 and we're left with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 21

On to step 4:
96 divided by 21 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 254.0
If we subtract 84 from 96, we get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 21

Advancing to step 5:
When dividing 120 by 21, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 2545.0
If we take 105 away from 120, we end up with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 21

Step 6:
152 divided by 21 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 25457.0
If we subtract 147 from 152, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 21 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 25457.2
Subtract 42 from 50 to get 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 8:
When dividing 80 by 21, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 25457.23
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
170 divided by 21 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 25457.238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
20 divided by 21 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 25457.238
If we subtract 0 from 20, we 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.

Going ahead to step 11:
200 divided by 21 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 25457.23809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 25457.238095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
If we divide 50 by 21, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 25457.2380952
Subtract 42 from 50 to get 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 14:
80 divided by 21 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 25457.23809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 25457.23809523 and a remainder of 1.7e-08.
