We're dividing 133410 by 21 
Our goal is to divide 133410 by 21.

Going ahead to step 1:
The number 21 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 21

Let's proceed to step 2:
21 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 21

On to step 3:
When dividing 133 by 21, we get 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 126 from 133, we get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 21

Advancing to step 4:
When dividing 74 by 21, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtracting 63 from 74 leaves us with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 21

Moving on to step 5:
111 divided by 21 is 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 635.0
The remainder is 6 after subtracting 105 from 111.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 21

Let's proceed to step 6:
21 goes into 60 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 6352.0
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
The number 21 fits into 180 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 6352.8
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 6352.85
Subtract 105 from 120 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 9:
When dividing 150 by 21, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 6352.857
Subtracting 147 from 150 leaves us 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.

Step 10:
The number 21 fits into 30 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 6352.8571
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.

Advancing to step 11:
If we divide 90 by 21, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 6352.85714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
21 goes into 60 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 6352.857142
Deduct 42 from 60 and we're left 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.

On to step 13:
If we divide 180 by 21, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 6352.8571428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 6352.85714285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 6352.85714285 and a remainder of 1.5e-08.
