Let's divide 90030380 by 315
We want to divide 90030380 by 315.

Moving on to step 1:
The number 315 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 315

Step 2:
315 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Bring next digit (0) of the dividend behind the 90 and repeat the process: 900 / 315

Going ahead to step 3:
315 can be fit into 900 2 times, resulting in a remainder of 270.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 630 away from 900, we end up with 270.
Take the next digit (3) from the dividend and append it to 270, then repeat: 2703 / 315

Moving on to step 4:
315 goes into 2703 8 times with a remainder of 183.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 2520 from 2703 leaves us with 183.
Fetch the next digit (0) from the dividend, attach it to 183 and continue: 1830 / 315

Moving on to step 5:
315 goes into 1830 5 times with a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 285.0
The remainder is 255 after subtracting 1575 from 1830.
Append the next digit (3) from the dividend to 255 and continue with: 2553 / 315

Let's proceed to step 6:
315 can be fit into 2553 8 times, resulting in a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 2858.0
Subtract 2520 from 2553 to get 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 315

Step 7:
If we divide 338 by 315, we get 1 and a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 28581.0
Subtract 315 from 338 to get 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 315

On to step 8:
315 goes into 230 0 times with a remainder of 230.
The next digit of our result is 0. 
Result so far: 285810.0
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 9:
2300 divided by 315 is 7 with a remainder of 95.
Use 7 as the next digit of our solution. 
Result so far: 285810.7
Subtracting 2205 from 2300 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 10:
950 divided by 315 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 285810.73
Subtracting 945 from 950 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
The number 315 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 285810.73
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
The number 315 fits into 500 1 times, leaving a remainder of 185.
Put 1 as the next digit of the answer. 
Result so far: 285810.7301
If we subtract 315 from 500, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 13:
315 goes into 1850 5 times with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 285810.73015
Subtracting 1575 from 1850 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 14:
The number 315 fits into 2750 8 times, leaving a remainder of 230.
Write down 8 as next digit of the result. 
Result so far: 285810.730158
Deduct 2520 from 2750 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 15:
2300 divided by 315 is 7 with a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 285810.7301587
Subtracting 2205 from 2300 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 16:
The number 315 fits into 950 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 285810.73015873
The remainder is 5 after subtracting 945 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 285810.73015873 with a remaining 5e-09.
