We're dividing 996650 by 21 
We want to figure out the number of times 996650 can be divided by 21.

Going ahead to step 1:
21 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 21

Let's proceed to step 2:
99 divided by 21 is 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 84 from 99 and we're left with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 21

Moving on to step 3:
If we divide 156 by 21, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtracting 147 from 156 leaves us with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 21

On to step 4:
21 goes into 96 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 474.0
Deduct 84 from 96 and we're left with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 21

Advancing to step 5:
If we divide 125 by 21, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 4745.0
If we subtract 105 from 125, we get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 21

Advancing to step 6:
200 divided by 21 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 47459.0
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.

Moving on to step 7:
110 divided by 21 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 47459.5
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.

Let's proceed to step 8:
50 divided by 21 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 47459.52
The remainder is 8 after subtracting 42 from 50.
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 9:
21 goes into 80 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 47459.523
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.

Advancing to step 10:
21 goes into 170 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 47459.5238
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.

Advancing to step 11:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 47459.5238
The remainder is 20 after subtracting 0 from 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 12:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 47459.523809
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 13:
When dividing 110 by 21, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 47459.5238095
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.

Advancing to step 14:
50 divided by 21 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 47459.52380952
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.

The final outcome is 47459.52380952, with a leftover of 8e-09.
