We're dividing 599416 by 21 
We want to divide 599416 by 21.

Step 1:
21 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 21

Let's proceed to step 2:
If we divide 59 by 21, we get 2 and a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 42 from 59 and we're left with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 21

Let's proceed to step 3:
When dividing 179 by 21, we get 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 168 from 179 to get 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 21

Advancing to step 4:
21 can be fit into 114 5 times, resulting in a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 285.0
Deduct 105 from 114 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 21

Moving on to step 5:
If we divide 91 by 21, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 2854.0
Deduct 84 from 91 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 21

Step 6:
21 goes into 76 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 28543.0
If we take 63 away from 76, 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.

Advancing to step 7:
When dividing 130 by 21, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 28543.6
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.

Let's proceed to step 8:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 28543.61
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
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: 28543.619
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.

Step 10:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 28543.619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 28543.61904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
If we divide 160 by 21, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 28543.619047
Deduct 147 from 160 and we're left 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.

Step 13:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 28543.6190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
21 goes into 40 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 28543.61904761
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.

Our division results in 28543.61904761 with a remaining 1.9e-08.
