Let's divide 89087040 by 312
We're looking to find how many times 312 goes into 89087040.

Step 1:
312 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 312

On to step 2:
If we divide 89 by 312, we get 0 and a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Bring next digit (0) of the dividend behind the 89 and repeat the process: 890 / 312

Step 3:
When dividing 890 by 312, we get 2 with a remainder of 266.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 624 away from 890, we end up with 266.
Fetch the next digit (8) from the dividend, attach it to 266 and continue: 2668 / 312

Let's proceed to step 4:
312 can be fit into 2668 8 times, resulting in a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 2496 from 2668 and we're left with 172.
Include the next digit (7) from the dividend after 172, then repeat: 1727 / 312

Let's proceed to step 5:
If we divide 1727 by 312, we get 5 and a remainder of 167.
The number 5 becomes the next digit in our result. 
Result so far: 285.0
Deduct 1560 from 1727 and we're left with 167.
Grab the next digit (0) from the dividend, add it to 167, then carry on: 1670 / 312

On to step 6:
1670 divided by 312 is 5 with a remainder of 110.
The next digit of our result is 5. 
Result so far: 2855.0
If we subtract 1560 from 1670, we get 110.
Take the next digit (4) from the dividend and append it to 110, then repeat: 1104 / 312

Moving on to step 7:
312 goes into 1104 3 times with a remainder of 168.
The next digit of our result is 3. 
Result so far: 28553.0
Subtracting 936 from 1104 leaves us with 168.
Append the next digit (0) from the dividend to 168 and continue with: 1680 / 312

Let's proceed to step 8:
The number 312 fits into 1680 5 times, leaving a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 285535.0
The remainder is 120 after subtracting 1560 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
When dividing 1200 by 312, we get 3 with a remainder of 264.
Write down 3 as next digit of the result. 
Result so far: 285535.3
If we subtract 936 from 1200, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 10:
312 can be fit into 2640 8 times, resulting in a remainder of 144.
The next digit of our result is 8. 
Result so far: 285535.38
Subtracting 2496 from 2640 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 11:
If we divide 1440 by 312, we get 4 and a remainder of 192.
The number 4 becomes the next digit in our result. 
Result so far: 285535.384
Subtracting 1248 from 1440 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 12:
If we divide 1920 by 312, we get 6 and a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 285535.3846
Subtract 1872 from 1920 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
The number 312 fits into 480 1 times, leaving a remainder of 168.
Write down 1 as next digit of the result. 
Result so far: 285535.38461
Deduct 312 from 480 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 14:
When dividing 1680 by 312, we get 5 with a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 285535.384615
Subtract 1560 from 1680 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 15:
When dividing 1200 by 312, we get 3 with a remainder of 264.
Write down 3 as next digit of the result. 
Result so far: 285535.3846153
If we take 936 away from 1200, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 16:
312 goes into 2640 8 times with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 285535.38461538
Subtracting 2496 from 2640 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

In conclusion, the division gives 285535.38461538 with a balance of 1.44e-07.
