988569 ÷ 40 
We want to divide 988569 by 40.

Step 1:
The number 40 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 40

Advancing to step 2:
98 divided by 40 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 80 from 98 and we're left with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 40

Moving on to step 3:
188 divided by 40 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtracting 160 from 188 leaves us with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 40

Let's proceed to step 4:
The number 40 fits into 285 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 247.0
The remainder is 5 after subtracting 280 from 285.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 40

Let's proceed to step 5:
40 goes into 56 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 2471.0
Subtract 40 from 56 to get 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 40

Going ahead to step 6:
The number 40 fits into 169 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 24714.0
Subtracting 160 from 169 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 40 fits into 90 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 24714.2
The remainder is 10 after subtracting 80 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 40 fits into 100 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 24714.22
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 24714.22 with a remainder of 0.02.
