We divide 140328 by 21
Our goal is to divide 140328 by 21.

Going ahead to step 1:
1 divided by 21 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 21

Advancing to step 2:
21 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 21

On to step 3:
21 can be fit into 140 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 126 from 140 and we're left with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 21

Step 4:
When dividing 143 by 21, we get 6 with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 126 from 143 to get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 21

On to step 5:
When dividing 172 by 21, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 668.0
If we subtract 168 from 172, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 21

Step 6:
48 divided by 21 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 6682.0
If we subtract 42 from 48, 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.

Going ahead to step 7:
When dividing 60 by 21, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 6682.2
If we subtract 42 from 60, we 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.

Moving on to step 8:
If we divide 180 by 21, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 6682.28
Deduct 168 from 180 and we're left 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.

On to step 9:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 6682.285
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.

On to step 10:
When dividing 150 by 21, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 6682.2857
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 11:
21 goes into 30 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 6682.28571
Subtracting 21 from 30 leaves us 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.

Step 12:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 6682.285714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
21 goes into 60 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 6682.2857142
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.

Let's proceed to step 14:
21 goes into 180 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 6682.28571428
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.

After the division, we end up with 6682.28571428 and a remainder of 1.2e-08.
