We're dividing 19753292 by 21 
Let's see how many times 21 fits into 19753292.

Going ahead to step 1:
21 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 21

On to step 2:
When dividing 19 by 21, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 21

Moving on to step 3:
When dividing 197 by 21, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 189 away from 197, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 21

On to step 4:
When dividing 85 by 21, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we subtract 84 from 85, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 21

On to step 5:
13 divided by 21 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 940.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 21

Moving on to step 6:
21 goes into 132 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 9406.0
Deduct 126 from 132 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 21

Moving on to step 7:
21 can be fit into 69 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 94063.0
Subtract 63 from 69 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 21

Advancing to step 8:
21 can be fit into 62 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 940632.0
Subtract 42 from 62 to 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.

Going ahead to step 9:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 940632.9
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 940632.95
If we take 105 away from 110, we end up with 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 11:
The number 21 fits into 50 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 940632.952
If we subtract 42 from 50, we get 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 12:
If we divide 80 by 21, we get 3 and a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 940632.9523
If we take 63 away from 80, we end up 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.

Let's proceed to step 13:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 940632.95238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
21 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 940632.95238
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.

Moving on to step 15:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 940632.9523809
Deduct 189 from 200 and we're left 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 16:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 940632.95238095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 940632.95238095 with a remainder of 5e-09.
