348501 divided by 90 
Our goal is to divide 348501 by 90.

Step 1:
The number 90 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 90

Let's proceed to step 2:
When dividing 34 by 90, we get 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 90

Moving on to step 3:
348 divided by 90 is 3 with a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 270 from 348 leaves us with 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 90

Step 4:
When dividing 785 by 90, we get 8 with a remainder of 65.
The next digit of our result is 8. 
Result so far: 38.0
Subtracting 720 from 785 leaves us with 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 90

On to step 5:
90 goes into 650 7 times with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 387.0
If we subtract 630 from 650, we get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 90

Going ahead to step 6:
90 goes into 201 2 times with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 3872.0
If we subtract 180 from 201, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
90 can be fit into 210 2 times, resulting in a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 3872.2
If we take 180 away from 210, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
90 goes into 300 3 times with a remainder of 30.
The next digit of our result is 3. 
Result so far: 3872.23
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 90 is 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 3872.233
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 3872.233, with a leftover of 0.003.
