We look at the division of 30812435 by 864 
We want to divide 30812435 by 864.

Step 1:
When dividing 3 by 864, 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.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 864

Let's proceed to step 2:
The number 864 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 864

Step 3:
864 can be fit into 308 0 times, resulting in a remainder of 308.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 308, we end up with 308.
Include the next digit (1) from the dividend after 308, then repeat: 3081 / 864

On to step 4:
The number 864 fits into 3081 3 times, leaving a remainder of 489.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2592 from 3081 and we're left with 489.
Grab the next digit (2) from the dividend, add it to 489, then carry on: 4892 / 864

Going ahead to step 5:
4892 divided by 864 is 5 with a remainder of 572.
The next digit of our result is 5. 
Result so far: 35.0
Deduct 4320 from 4892 and we're left with 572.
Fetch the next digit (4) from the dividend, attach it to 572 and continue: 5724 / 864

Step 6:
864 goes into 5724 6 times with a remainder of 540.
Write down 6 as next digit of the result. 
Result so far: 356.0
The remainder is 540 after subtracting 5184 from 5724.
Include the next digit (3) from the dividend after 540, then repeat: 5403 / 864

Advancing to step 7:
864 goes into 5403 6 times with a remainder of 219.
The next digit of our result is 6. 
Result so far: 3566.0
Subtract 5184 from 5403 to get 219.
Fetch the next digit (5) from the dividend, attach it to 219 and continue: 2195 / 864

Moving on to step 8:
864 can be fit into 2195 2 times, resulting in a remainder of 467.
Put 2 as the next digit of the answer. 
Result so far: 35662.0
Deduct 1728 from 2195 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Moving on to step 9:
864 goes into 4670 5 times with a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 35662.5
If we subtract 4320 from 4670, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 10:
864 goes into 3500 4 times with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 35662.54
If we subtract 3456 from 3500, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
864 goes into 440 0 times with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 35662.54
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
4400 divided by 864 is 5 with a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 35662.5405
Subtracting 4320 from 4400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
864 can be fit into 800 0 times, resulting in a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 35662.5405
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 14:
If we divide 8000 by 864, we get 9 and a remainder of 224.
Put 9 as the next digit of the answer. 
Result so far: 35662.540509
Subtracting 7776 from 8000 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 15:
864 can be fit into 2240 2 times, resulting in a remainder of 512.
Write down 2 as next digit of the result. 
Result so far: 35662.5405092
Deduct 1728 from 2240 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 16:
If we divide 5120 by 864, we get 5 and a remainder of 800.
Put 5 as the next digit of the answer. 
Result so far: 35662.54050925
Deduct 4320 from 5120 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

In conclusion, the division gives 35662.54050925 with a balance of 8e-07.
