Let's divide 455597 by 21
Let's see how many times 21 fits into 455597.

Step 1:
4 divided by 21 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 21

Let's proceed to step 2:
If we divide 45 by 21, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 3 after subtracting 42 from 45.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 21

Advancing to step 3:
35 divided by 21 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 21 from 35 leaves us with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 21

Moving on to step 4:
The number 21 fits into 145 6 times, leaving a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 216.0
If we take 126 away from 145, we end up with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 21

Let's proceed to step 5:
199 divided by 21 is 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 2169.0
If we subtract 189 from 199, we get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 21

Moving on to step 6:
If we divide 107 by 21, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 21695.0
Subtract 105 from 107 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 21695.0
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.

On to step 8:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 21695.09
Deduct 189 from 200 and we're left 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.

Advancing to step 9:
When dividing 110 by 21, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 21695.095
If we subtract 105 from 110, 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.

Moving on to step 10:
When dividing 50 by 21, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 21695.0952
Subtracting 42 from 50 leaves us 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.

Let's proceed to step 11:
When dividing 80 by 21, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 21695.09523
Subtracting 63 from 80 leaves us 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.

Let's proceed to step 12:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 21695.095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
20 divided by 21 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 21695.095238
Subtract 0 from 20 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.

On to step 14:
The number 21 fits into 200 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 21695.09523809
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.

In conclusion, the division gives 21695.09523809 with a balance of 1.1e-08.
