984380 ÷ 40 
We're looking to find how many times 40 goes into 984380.

Step 1:
When dividing 9 by 40, we get 0 with 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.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 40

Moving on to step 2:
When dividing 98 by 40, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 80 from 98 and we're left with 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 40

Moving on to step 3:
184 divided by 40 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 160 from 184 leaves us with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 40

Step 4:
The number 40 fits into 243 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 246.0
If we subtract 240 from 243, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 40

Advancing to step 5:
40 goes into 38 0 times with a remainder of 38.
The next digit of our result is 0. 
Result so far: 2460.0
The remainder is 38 after subtracting 0 from 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 40

Moving on to step 6:
The number 40 fits into 380 9 times, leaving a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 24609.0
If we take 360 away from 380, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 24609.5
Subtracting 200 from 200 leaves us 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.

Step 8:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 24609.5
Subtracting 0 from 0 leaves us 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.

Advancing to step 9:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 24609.5
Subtracting 0 from 0 leaves us 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 24609.5, and the remainder is 0.0.
