991481 ÷ 20 
We want to figure out the number of times 991481 can be divided by 20.

Let's proceed to step 1:
20 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 20

Step 2:
20 can be fit into 99 4 times, resulting in a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 19 after subtracting 80 from 99.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 20

Going ahead to step 3:
If we divide 191 by 20, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtracting 180 from 191 leaves us with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 20

Step 4:
20 can be fit into 114 5 times, resulting in a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 495.0
The remainder is 14 after subtracting 100 from 114.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 20

Advancing to step 5:
20 goes into 148 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 4957.0
If we subtract 140 from 148, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 20

Let's proceed to step 6:
The number 20 fits into 81 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 49574.0
Subtracting 80 from 81 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
20 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 49574.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 49574.05
Deduct 100 from 100 and we're left 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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 49574.05
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.

Let's proceed to step 10:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 49574.05
If we take 0 away from 0, 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.

The quotient of the division is 49574.05, and the remainder is 0.0.
