Let's divide 14197581 by 21
We want to divide 14197581 by 21.

Let's proceed to step 1:
When dividing 1 by 21, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 21

Step 2:
If we divide 14 by 21, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 21

On to step 3:
21 goes into 141 6 times with a remainder of 15.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 126 from 141 and we're left with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 21

Let's proceed to step 4:
The number 21 fits into 159 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Deduct 147 from 159 and we're left with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 21

On to step 5:
127 divided by 21 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 676.0
Subtracting 126 from 127 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 21

Going ahead to step 6:
15 divided by 21 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 6760.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 21

Going ahead to step 7:
158 divided by 21 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 67607.0
Deduct 147 from 158 and we're left with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 21

Step 8:
When dividing 111 by 21, we get 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 676075.0
If we subtract 105 from 111, 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 9:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 676075.2
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.

On to step 10:
21 goes into 180 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 676075.28
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.

Let's proceed to step 11:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 676075.285
If we subtract 105 from 120, we 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.

Step 12:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 676075.2857
Subtract 147 from 150 to 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 13:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 676075.28571
The remainder is 9 after subtracting 21 from 30.
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 14:
21 goes into 90 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 676075.285714
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.

Moving on to step 15:
When dividing 60 by 21, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 676075.2857142
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.

Let's proceed to step 16:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 676075.28571428
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.

The quotient of the division is 676075.28571428, and the remainder is 1.2e-08.
