We look at the division of 39369 by 40 
Our goal is to divide 39369 by 40.

Going ahead to step 1:
40 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 40

Going ahead to step 2:
40 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 40

On to step 3:
The number 40 fits into 393 9 times, leaving a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 33 after subtracting 360 from 393.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 40

On to step 4:
The number 40 fits into 336 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 98.0
The remainder is 16 after subtracting 320 from 336.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 40

On to step 5:
When dividing 169 by 40, we get 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 984.0
If we subtract 160 from 169, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 6:
40 goes into 90 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 984.2
Deduct 80 from 90 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 40, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 984.22
Subtracting 80 from 100 leaves us 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.

The final outcome is 984.22, with a leftover of 0.02.
