We look at the division of 202193 by 21 
We want to figure out the number of times 202193 can be divided by 21.

Moving on to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 21

Step 2:
When dividing 20 by 21, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 21

Advancing to step 3:
21 can be fit into 202 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 189 from 202 to get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 21

Let's proceed to step 4:
The number 21 fits into 131 6 times, leaving a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we take 126 away from 131, we end up with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 21

Going ahead to step 5:
21 goes into 59 2 times with a remainder of 17.
The next digit of our result is 2. 
Result so far: 962.0
If we subtract 42 from 59, we get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 21

On to step 6:
If we divide 173 by 21, we get 8 and a remainder of 5.
The next digit of our result is 8. 
Result so far: 9628.0
The remainder is 5 after subtracting 168 from 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
When dividing 50 by 21, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 9628.2
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 8:
80 divided by 21 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 9628.23
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.

On to step 9:
170 divided by 21 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 9628.238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 21 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9628.238
If we subtract 0 from 20, we 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.

Let's proceed to step 11:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 9628.23809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 12:
If we divide 110 by 21, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9628.238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
When dividing 50 by 21, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 9628.2380952
Deduct 42 from 50 and we're left 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.

Advancing to step 14:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 9628.23809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 9628.23809523, and the remainder is 1.7e-08.
