18820157 ÷ 864 
We want to divide 18820157 by 864.

On to step 1:
The number 864 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 864

Advancing to step 2:
18 divided by 864 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 864

Moving on to step 3:
188 divided by 864 is 0 with a remainder of 188.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 188, we end up with 188.
Fetch the next digit (2) from the dividend, attach it to 188 and continue: 1882 / 864

Let's proceed to step 4:
864 goes into 1882 2 times with a remainder of 154.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1728 away from 1882, we end up with 154.
Fetch the next digit (0) from the dividend, attach it to 154 and continue: 1540 / 864

Moving on to step 5:
When dividing 1540 by 864, we get 1 with a remainder of 676.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 676 after subtracting 864 from 1540.
Take the next digit (1) from the dividend and append it to 676, then repeat: 6761 / 864

On to step 6:
If we divide 6761 by 864, we get 7 and a remainder of 713.
The next digit of our result is 7. 
Result so far: 217.0
Subtracting 6048 from 6761 leaves us with 713.
Append the next digit (5) from the dividend to 713 and continue with: 7135 / 864

Let's proceed to step 7:
The number 864 fits into 7135 8 times, leaving a remainder of 223.
Use 8 as the next digit of our solution. 
Result so far: 2178.0
Subtract 6912 from 7135 to get 223.
Include the next digit (7) from the dividend after 223, then repeat: 2237 / 864

On to step 8:
864 can be fit into 2237 2 times, resulting in a remainder of 509.
Use 2 as the next digit of our solution. 
Result so far: 21782.0
Subtract 1728 from 2237 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Moving on to step 9:
When dividing 5090 by 864, we get 5 with a remainder of 770.
The number 5 becomes the next digit in our result. 
Result so far: 21782.5
If we take 4320 away from 5090, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Advancing to step 10:
If we divide 7700 by 864, we get 8 and a remainder of 788.
Record the quotient 8 as the next digit in the result. 
Result so far: 21782.58
If we take 6912 away from 7700, we end up with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Moving on to step 11:
7880 divided by 864 is 9 with a remainder of 104.
The next digit of our result is 9. 
Result so far: 21782.589
Subtract 7776 from 7880 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 12:
When dividing 1040 by 864, we get 1 with a remainder of 176.
Write down 1 as next digit of the result. 
Result so far: 21782.5891
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.

Step 13:
If we divide 1760 by 864, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 21782.58912
The remainder is 32 after subtracting 1728 from 1760.
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:
If we divide 320 by 864, we get 0 and a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 21782.58912
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
When dividing 3200 by 864, we get 3 with a remainder of 608.
Use 3 as the next digit of our solution. 
Result so far: 21782.5891203
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.

Let's proceed to step 16:
If we divide 6080 by 864, we get 7 and a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 21782.58912037
The remainder is 32 after subtracting 6048 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 21782.58912037 with a balance of 3.2e-08.
