We're dividing 598683 by 21 
Let's see how many times 21 fits into 598683.

Let's proceed to step 1:
The number 21 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 21

Going ahead to step 2:
If we divide 59 by 21, we get 2 and a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 42 from 59 and we're left with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 21

Let's proceed to step 3:
If we divide 178 by 21, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 168 from 178 to get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 21

Going ahead to step 4:
The number 21 fits into 106 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 285.0
The remainder is 1 after subtracting 105 from 106.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 21

Going ahead to step 5:
21 can be fit into 18 0 times, resulting in a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 2850.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 21

Moving on to step 6:
When dividing 183 by 21, we get 8 with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 28508.0
Subtract 168 from 183 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
150 divided by 21 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 28508.7
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
When dividing 30 by 21, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 28508.71
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 28508.714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
60 divided by 21 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 28508.7142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
21 goes into 180 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 28508.71428
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 21, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 28508.714285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
When dividing 150 by 21, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 28508.7142857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
If we divide 30 by 21, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 28508.71428571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 28508.71428571 with a remaining 9e-09.
