90640336 ÷ 40 
Let's see how many times 40 fits into 90640336.

Step 1:
9 divided by 40 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 40

Going ahead to step 2:
40 goes into 90 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 10 after subtracting 80 from 90.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 40

Going ahead to step 3:
40 goes into 106 2 times with a remainder of 26.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 80 from 106 to get 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 40

Advancing to step 4:
264 divided by 40 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 226.0
Deduct 240 from 264 and we're left with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 40

Going ahead to step 5:
If we divide 240 by 40, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 2266.0
Deduct 240 from 240 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 40

Step 6:
40 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 22660.0
If we subtract 0 from 3, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 40

Step 7:
40 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 226600.0
Subtract 0 from 33 to get 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 40

Step 8:
The number 40 fits into 336 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 2266008.0
Subtract 320 from 336 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 40, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 2266008.4
If we take 160 away from 160, 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.

Moving on to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2266008.4
Subtract 0 from 0 to 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.

Step 11:
0 divided by 40 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2266008.4
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 final outcome is 2266008.4, with a leftover of 0.0.
