307700 divided by 90 
We want to divide 307700 by 90.

Moving on to step 1:
3 divided by 90 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 90

Step 2:
The number 90 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 90

Advancing to step 3:
If we divide 307 by 90, we get 3 and a remainder of 37.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 270 from 307, we get 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 90

Let's proceed to step 4:
377 divided by 90 is 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 360 from 377 and we're left with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 90

Let's proceed to step 5:
90 can be fit into 170 1 times, resulting in a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 341.0
Deduct 90 from 170 and we're left with 80.
Take the next digit (0) from the dividend and append it to 80, then repeat: 800 / 90

Step 6:
If we divide 800 by 90, we get 8 and a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 3418.0
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 7:
90 goes into 800 8 times with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 3418.8
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 3418.88
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 3418.88 with a remainder of 0.08.
