We're dividing 658162 by 21 
Our goal is to divide 658162 by 21.

Going ahead to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 21

Moving on to step 2:
When dividing 65 by 21, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 2 after subtracting 63 from 65.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 21

On to step 3:
21 can be fit into 28 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 21 from 28 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 21

Step 4:
When dividing 71 by 21, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 313.0
Subtracting 63 from 71 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 21

Let's proceed to step 5:
If we divide 86 by 21, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3134.0
Subtracting 84 from 86 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 21

Advancing to step 6:
If we divide 22 by 21, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 31341.0
If we take 21 away from 22, 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.

Advancing to step 7:
10 divided by 21 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 31341.0
If we take 0 away from 10, we end up 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.

Going ahead to step 8:
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: 31341.04
Subtract 84 from 100 to get 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 9:
21 goes into 160 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 31341.047
Subtracting 147 from 160 leaves us 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.

Going ahead to step 10:
130 divided by 21 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 31341.0476
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.

Moving on to step 11:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 31341.04761
Deduct 21 from 40 and we're left 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.

Let's proceed to step 12:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 31341.047619
Deduct 189 from 190 and we're left 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.

Advancing to step 13:
21 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 31341.047619
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.

Advancing to step 14:
100 divided by 21 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 31341.04761904
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.

Our division results in 31341.04761904 with a remaining 1.6e-08.
