We divide 347663 by 90
We want to figure out the number of times 347663 can be divided by 90.

Let's proceed to step 1:
When dividing 3 by 90, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 90

Step 2:
90 can be fit into 34 0 times, resulting in a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 90

Advancing to step 3:
90 goes into 347 3 times with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 270 from 347, we get 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 90

On to step 4:
776 divided by 90 is 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 38.0
Deduct 720 from 776 and we're left with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 90

On to step 5:
When dividing 566 by 90, we get 6 with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 386.0
The remainder is 26 after subtracting 540 from 566.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 90

Let's proceed to step 6:
The number 90 fits into 263 2 times, leaving a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 3862.0
Deduct 180 from 263 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 7:
830 divided by 90 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 3862.9
If we subtract 810 from 830, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
90 can be fit into 200 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 3862.92
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 90, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 3862.922
If we subtract 180 from 200, we get 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 quotient of the division is 3862.922, and the remainder is 0.002.
