We divide 339336 by 40
We want to figure out the number of times 339336 can be divided by 40.

Moving on to step 1:
If we divide 3 by 40, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 40

Moving on to step 2:
The number 40 fits into 33 0 times, leaving a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 40

Let's proceed to step 3:
339 divided by 40 is 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 320 from 339 and we're left with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 40

Step 4:
When dividing 193 by 40, we get 4 with a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 84.0
The remainder is 33 after subtracting 160 from 193.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 40

On to step 5:
If we divide 333 by 40, we get 8 and a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 848.0
If we take 320 away from 333, we end up with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 40

Let's proceed to step 6:
When dividing 136 by 40, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 8483.0
Subtracting 120 from 136 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
160 divided by 40 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 8483.4
If we subtract 160 from 160, 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.

Moving on to step 8:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8483.4
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.

Advancing to step 9:
When dividing 0 by 40, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8483.4
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 8483.4, with a leftover of 0.0.
