We're dividing 336939 by 90 
We want to divide 336939 by 90.

Moving on to step 1:
90 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 90

Moving on to step 2:
90 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: 0.0
Deduct 0 from 33 and we're left with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 90

Step 3:
If we divide 336 by 90, we get 3 and a remainder of 66.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 270 from 336, we get 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 90

Step 4:
90 can be fit into 669 7 times, resulting in a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Deduct 630 from 669 and we're left with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 90

Going ahead to step 5:
The number 90 fits into 393 4 times, leaving a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 374.0
Subtract 360 from 393 to get 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 90

Advancing to step 6:
The number 90 fits into 339 3 times, leaving a remainder of 69.
The next digit of our result is 3. 
Result so far: 3743.0
The remainder is 69 after subtracting 270 from 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
90 goes into 690 7 times with a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 3743.7
If we subtract 630 from 690, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
600 divided by 90 is 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 3743.76
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
90 goes into 600 6 times with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 3743.766
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 3743.766 and a remainder of 0.006.
