975318 ÷ 21 
We want to figure out the number of times 975318 can be divided by 21.

Let's proceed 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
Subtract 0 from 9 to get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 21

Going ahead to step 2:
21 can be fit into 97 4 times, resulting in a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 84 away from 97, we end up with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 21

Going ahead to step 3:
If we divide 135 by 21, we get 6 and a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtract 126 from 135 to get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 21

Going ahead to step 4:
The number 21 fits into 93 4 times, leaving a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 464.0
If we take 84 away from 93, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 21

Moving on to step 5:
The number 21 fits into 91 4 times, leaving a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4644.0
Deduct 84 from 91 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 21

On to step 6:
21 can be fit into 78 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 46443.0
Subtract 63 from 78 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 7:
150 divided by 21 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 46443.7
If we subtract 147 from 150, we 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.

Let's proceed to step 8:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 46443.71
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.

Let's proceed to step 9:
When dividing 90 by 21, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 46443.714
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.

Moving on to step 10:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 46443.7142
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.

Step 11:
21 goes into 180 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 46443.71428
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.

Moving on to step 12:
21 goes into 120 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 46443.714285
Subtracting 105 from 120 leaves us with 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 13:
If we divide 150 by 21, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 46443.7142857
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.

Advancing to step 14:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 46443.71428571
Subtract 21 from 30 to 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.

The final outcome is 46443.71428571, with a leftover of 9e-09.
