Let's divide 390076 by 90
Let's see how many times 90 fits into 390076.

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
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 90

Going ahead to step 2:
When dividing 39 by 90, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 90

Step 3:
90 can be fit into 390 4 times, resulting in a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 360 from 390 to get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 90

Advancing to step 4:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 30 after subtracting 270 from 300.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 90

Advancing to step 5:
If we divide 307 by 90, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 433.0
The remainder is 37 after subtracting 270 from 307.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 90

Step 6:
If we divide 376 by 90, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 4334.0
Subtract 360 from 376 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
90 goes into 160 1 times with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 4334.1
If we take 90 away from 160, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
90 goes into 700 7 times with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 4334.17
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
90 goes into 700 7 times with a remainder of 70.
The next digit of our result is 7. 
Result so far: 4334.177
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 4334.177 and a remainder of 0.007.
