We divide 19973 by 21
We want to divide 19973 by 21.

Step 1:
1 divided by 21 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 21

Step 2:
If we divide 19 by 21, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 21

On to step 3:
199 divided by 21 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 10 after subtracting 189 from 199.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 21

Step 4:
The number 21 fits into 107 5 times, leaving a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
The remainder is 2 after subtracting 105 from 107.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 21

On to step 5:
21 goes into 23 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 951.0
The remainder is 2 after subtracting 21 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
20 divided by 21 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 951.0
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 7:
200 divided by 21 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 951.09
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.

Advancing to step 8:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 951.095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
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: 951.0952
Subtracting 42 from 50 leaves us 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.

Moving on to step 10:
When dividing 80 by 21, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 951.09523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 951.095238
Subtracting 168 from 170 leaves us 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.

Step 12:
When dividing 20 by 21, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 951.095238
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.

Advancing to step 13:
21 goes into 200 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 951.09523809
If we take 189 away from 200, we end up 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.

The final outcome is 951.09523809, with a leftover of 1.1e-08.
