We're dividing 18588497 by 864 
We're looking to find how many times 864 goes into 18588497.

Step 1:
864 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 864

Moving on to step 2:
When dividing 18 by 864, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 864

Step 3:
864 goes into 185 0 times with a remainder of 185.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 185, we get 185.
Take the next digit (8) from the dividend and append it to 185, then repeat: 1858 / 864

On to step 4:
The number 864 fits into 1858 2 times, leaving a remainder of 130.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1728 from 1858 leaves us with 130.
Include the next digit (8) from the dividend after 130, then repeat: 1308 / 864

Going ahead to step 5:
The number 864 fits into 1308 1 times, leaving a remainder of 444.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 864 from 1308 to get 444.
Bring next digit (4) of the dividend behind the 444 and repeat the process: 4444 / 864

Let's proceed to step 6:
864 goes into 4444 5 times with a remainder of 124.
Put 5 as the next digit of the answer. 
Result so far: 215.0
Subtract 4320 from 4444 to get 124.
Append the next digit (9) from the dividend to 124 and continue with: 1249 / 864

Moving on to step 7:
The number 864 fits into 1249 1 times, leaving a remainder of 385.
Use 1 as the next digit of our solution. 
Result so far: 2151.0
If we take 864 away from 1249, we end up with 385.
Bring next digit (7) of the dividend behind the 385 and repeat the process: 3857 / 864

Going ahead to step 8:
864 can be fit into 3857 4 times, resulting in a remainder of 401.
The next digit of our result is 4. 
Result so far: 21514.0
If we take 3456 away from 3857, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 9:
864 can be fit into 4010 4 times, resulting in a remainder of 554.
Write down 4 as next digit of the result. 
Result so far: 21514.4
The remainder is 554 after subtracting 3456 from 4010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Advancing to step 10:
5540 divided by 864 is 6 with a remainder of 356.
The number 6 becomes the next digit in our result. 
Result so far: 21514.46
Subtract 5184 from 5540 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 11:
864 goes into 3560 4 times with a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 21514.464
If we take 3456 away from 3560, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 12:
When dividing 1040 by 864, we get 1 with a remainder of 176.
The next digit of our result is 1. 
Result so far: 21514.4641
Subtracting 864 from 1040 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 13:
1760 divided by 864 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 21514.46412
If we take 1728 away from 1760, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
320 divided by 864 is 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 21514.46412
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 15:
3200 divided by 864 is 3 with a remainder of 608.
Record the quotient 3 as the next digit in the result. 
Result so far: 21514.4641203
The remainder is 608 after subtracting 2592 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 16:
If we divide 6080 by 864, we get 7 and a remainder of 32.
The next digit of our result is 7. 
Result so far: 21514.46412037
Subtracting 6048 from 6080 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 21514.46412037 and a remainder of 3.2e-08.
