991408 divided by 20 
Our goal is to divide 991408 by 20.

Moving on to step 1:
9 divided by 20 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 20

Going ahead to step 2:
The number 20 fits into 99 4 times, leaving a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 80 from 99 to get 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 20

On to step 3:
The number 20 fits into 191 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 11 after subtracting 180 from 191.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 20

Let's proceed to step 4:
The number 20 fits into 114 5 times, leaving a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 495.0
Subtract 100 from 114 to get 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 20

Advancing to step 5:
20 can be fit into 140 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 4957.0
If we subtract 140 from 140, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 20

Step 6:
The number 20 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 49570.0
If we subtract 0 from 8, 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.

Going ahead to step 7:
If we divide 80 by 20, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 49570.4
If we take 80 away from 80, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 49570.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49570.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 49570.4 with a balance of 0.0.
