We're dividing 297550 by 21 
We want to figure out the number of times 297550 can be divided by 21.

On to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 21

Going ahead to step 2:
The number 21 fits into 29 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 21 from 29, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 21

On to step 3:
87 divided by 21 is 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 84 from 87 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 21

On to step 4:
When dividing 35 by 21, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 141.0
If we subtract 21 from 35, we get 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 21

On to step 5:
When dividing 145 by 21, we get 6 with a remainder of 19.
The next digit of our result is 6. 
Result so far: 1416.0
Subtract 126 from 145 to get 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 21

Let's proceed to step 6:
When dividing 190 by 21, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 14169.0
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 14169.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 21, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 14169.04
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 14169.047
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
130 divided by 21 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 14169.0476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 14169.04761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 14169.047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
When dividing 10 by 21, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 14169.047619
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
If we divide 100 by 21, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 14169.04761904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 14169.04761904 with a balance of 1.6e-08.
