We look at the division of 970910 by 21 
We want to divide 970910 by 21.

Step 1:
9 divided by 21 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 21

Step 2:
When dividing 97 by 21, we get 4 with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 84 from 97, we get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 21

Let's proceed to step 3:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 4 after subtracting 126 from 130.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 21

On to step 4:
The number 21 fits into 49 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 462.0
Subtracting 42 from 49 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 21

Step 5:
The number 21 fits into 71 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 4623.0
The remainder is 8 after subtracting 63 from 71.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 21

Let's proceed to step 6:
21 goes into 80 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 46233.0
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
If we divide 170 by 21, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 46233.8
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 46233.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
21 goes into 200 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 46233.809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
When dividing 110 by 21, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 46233.8095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
When dividing 50 by 21, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 46233.80952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
21 goes into 80 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 46233.809523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
170 divided by 21 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 46233.8095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
21 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 46233.8095238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 46233.8095238 with a remaining 2e-08.
