Let's divide 363465 by 90
We want to figure out the number of times 363465 can be divided by 90.

Moving on to step 1:
When dividing 3 by 90, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 90

Let's proceed to step 2:
The number 90 fits into 36 0 times, leaving a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 90

On to step 3:
If we divide 363 by 90, we get 4 and a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 360 away from 363, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 90

Going ahead to step 4:
34 divided by 90 is 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
The remainder is 34 after subtracting 0 from 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 90

Moving on to step 5:
90 goes into 346 3 times with a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 403.0
Deduct 270 from 346 and we're left with 76.
Grab the next digit (5) from the dividend, add it to 76, then carry on: 765 / 90

Advancing to step 6:
90 goes into 765 8 times with a remainder of 45.
The next digit of our result is 8. 
Result so far: 4038.0
The remainder is 45 after subtracting 720 from 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
The number 90 fits into 450 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4038.5
Subtracting 450 from 450 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4038.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 90 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4038.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 4038.5 and a remainder of 0.0.
