Let's divide 43329809 by 864
We want to figure out the number of times 43329809 can be divided by 864.

Advancing to step 1:
When dividing 4 by 864, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 864

On to step 2:
The number 864 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 864

Moving on to step 3:
864 goes into 433 0 times with a remainder of 433.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 433 after subtracting 0 from 433.
Include the next digit (2) from the dividend after 433, then repeat: 4332 / 864

Moving on to step 4:
When dividing 4332 by 864, we get 5 with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 4320 from 4332 leaves us with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 864

Moving on to step 5:
The number 864 fits into 129 0 times, leaving a remainder of 129.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we subtract 0 from 129, we get 129.
Append the next digit (8) from the dividend to 129 and continue with: 1298 / 864

On to step 6:
864 can be fit into 1298 1 times, resulting in a remainder of 434.
The next digit of our result is 1. 
Result so far: 501.0
If we take 864 away from 1298, we end up with 434.
Grab the next digit (0) from the dividend, add it to 434, then carry on: 4340 / 864

Moving on to step 7:
864 goes into 4340 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 5015.0
Deduct 4320 from 4340 and we're left with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 864

Going ahead to step 8:
The number 864 fits into 209 0 times, leaving a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 50150.0
Subtract 0 from 209 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 9:
864 goes into 2090 2 times with a remainder of 362.
Record the quotient 2 as the next digit in the result. 
Result so far: 50150.2
Subtract 1728 from 2090 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 10:
The number 864 fits into 3620 4 times, leaving a remainder of 164.
Use 4 as the next digit of our solution. 
Result so far: 50150.24
Subtracting 3456 from 3620 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 11:
864 goes into 1640 1 times with a remainder of 776.
Write down 1 as next digit of the result. 
Result so far: 50150.241
If we take 864 away from 1640, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Moving on to step 12:
7760 divided by 864 is 8 with a remainder of 848.
The number 8 becomes the next digit in our result. 
Result so far: 50150.2418
Subtract 6912 from 7760 to get 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Advancing to step 13:
864 can be fit into 8480 9 times, resulting in a remainder of 704.
Write down 9 as next digit of the result. 
Result so far: 50150.24189
The remainder is 704 after subtracting 7776 from 8480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Moving on to step 14:
7040 divided by 864 is 8 with a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 50150.241898
The remainder is 128 after subtracting 6912 from 7040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 15:
If we divide 1280 by 864, we get 1 and a remainder of 416.
The number 1 becomes the next digit in our result. 
Result so far: 50150.2418981
Deduct 864 from 1280 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 16:
If we divide 4160 by 864, we get 4 and a remainder of 704.
Write down 4 as next digit of the result. 
Result so far: 50150.24189814
Subtracting 3456 from 4160 leaves us with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Our division results in 50150.24189814 with a remaining 7.04e-07.
