We divide 850288 by 40
We're looking to find how many times 40 goes into 850288.

Step 1:
40 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 40

Going ahead to step 2:
40 can be fit into 85 2 times, resulting in a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 80 from 85 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 40

Going ahead to step 3:
If we divide 50 by 40, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 40 from 50 leaves us with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 40

Let's proceed to step 4:
40 can be fit into 102 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
The remainder is 22 after subtracting 80 from 102.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 40

Going ahead to step 5:
40 goes into 228 5 times with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 2125.0
If we subtract 200 from 228, we get 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 40

On to step 6:
288 divided by 40 is 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 21257.0
The remainder is 8 after subtracting 280 from 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
When dividing 80 by 40, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 21257.2
The remainder is 0 after subtracting 80 from 80.
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:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21257.2
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.

Step 9:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21257.2
If we subtract 0 from 0, we get 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 21257.2, and the remainder is 0.0.
