We're dividing 72533739 by 864 
Let's see how many times 864 fits into 72533739.

Step 1:
The number 864 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 864

On to step 2:
864 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Grab the next digit (5) from the dividend, add it to 72, then carry on: 725 / 864

Let's proceed to step 3:
If we divide 725 by 864, we get 0 and a remainder of 725.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 725 and we're left with 725.
Append the next digit (3) from the dividend to 725 and continue with: 7253 / 864

Moving on to step 4:
The number 864 fits into 7253 8 times, leaving a remainder of 341.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 6912 from 7253 to get 341.
Fetch the next digit (3) from the dividend, attach it to 341 and continue: 3413 / 864

Advancing to step 5:
864 goes into 3413 3 times with a remainder of 821.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
If we take 2592 away from 3413, we end up with 821.
Fetch the next digit (7) from the dividend, attach it to 821 and continue: 8217 / 864

Moving on to step 6:
If we divide 8217 by 864, we get 9 and a remainder of 441.
Record the quotient 9 as the next digit in the result. 
Result so far: 839.0
If we subtract 7776 from 8217, we get 441.
Grab the next digit (3) from the dividend, add it to 441, then carry on: 4413 / 864

Let's proceed to step 7:
The number 864 fits into 4413 5 times, leaving a remainder of 93.
The next digit of our result is 5. 
Result so far: 8395.0
The remainder is 93 after subtracting 4320 from 4413.
Bring next digit (9) of the dividend behind the 93 and repeat the process: 939 / 864

Going ahead to step 8:
When dividing 939 by 864, we get 1 with a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 83951.0
Subtract 864 from 939 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 9:
864 goes into 750 0 times with a remainder of 750.
Record the quotient 0 as the next digit in the result. 
Result so far: 83951.0
Subtract 0 from 750 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 10:
If we divide 7500 by 864, we get 8 and a remainder of 588.
The number 8 becomes the next digit in our result. 
Result so far: 83951.08
If we take 6912 away from 7500, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Advancing to step 11:
If we divide 5880 by 864, we get 6 and a remainder of 696.
Put 6 as the next digit of the answer. 
Result so far: 83951.086
If we subtract 5184 from 5880, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Let's proceed to step 12:
If we divide 6960 by 864, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 83951.0868
Subtracting 6912 from 6960 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
When dividing 480 by 864, we get 0 with a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 83951.0868
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 14:
864 goes into 4800 5 times with a remainder of 480.
The number 5 becomes the next digit in our result. 
Result so far: 83951.086805
Subtract 4320 from 4800 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 15:
4800 divided by 864 is 5 with a remainder of 480.
The number 5 becomes the next digit in our result. 
Result so far: 83951.0868055
If we subtract 4320 from 4800, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

After the division, we end up with 83951.0868055 and a remainder of 4.8e-06.
