Let's divide 972150 by 21
We want to divide 972150 by 21.

On to step 1:
When dividing 9 by 21, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 21

Step 2:
97 divided by 21 is 4 with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 84 from 97, we get 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 21

Step 3:
The number 21 fits into 132 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 46.0
If we take 126 away from 132, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 21

Going ahead to step 4:
If we divide 61 by 21, we get 2 and a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 462.0
If we take 42 away from 61, we end up with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 21

Step 5:
21 can be fit into 195 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 4629.0
If we take 189 away from 195, we end up with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 21

Moving on 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: 46292.0
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.

Advancing to step 7:
When dividing 180 by 21, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 46292.8
If we take 168 away from 180, we end up 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.

Step 8:
When dividing 120 by 21, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 46292.85
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.

Advancing to step 9:
When dividing 150 by 21, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 46292.857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
When dividing 30 by 21, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 46292.8571
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 11:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 46292.85714
Deduct 84 from 90 and we're left 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.

Moving on to step 12:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 46292.857142
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.

Going ahead to step 13:
21 goes into 180 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 46292.8571428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 46292.85714285
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.

In conclusion, the division gives 46292.85714285 with a balance of 1.5e-08.
