We're dividing 72165819 by 863 
Our goal is to divide 72165819 by 863.

Moving on to step 1:
The number 863 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 863

Moving on to step 2:
72 divided by 863 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 863

Step 3:
863 can be fit into 721 0 times, resulting in a remainder of 721.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 721 after subtracting 0 from 721.
Include the next digit (6) from the dividend after 721, then repeat: 7216 / 863

On to step 4:
When dividing 7216 by 863, we get 8 with a remainder of 312.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 6904 from 7216 to get 312.
Append the next digit (5) from the dividend to 312 and continue with: 3125 / 863

Advancing to step 5:
If we divide 3125 by 863, we get 3 and a remainder of 536.
The next digit of our result is 3. 
Result so far: 83.0
If we take 2589 away from 3125, we end up with 536.
Append the next digit (8) from the dividend to 536 and continue with: 5368 / 863

Moving on to step 6:
863 can be fit into 5368 6 times, resulting in a remainder of 190.
Use 6 as the next digit of our solution. 
Result so far: 836.0
Subtract 5178 from 5368 to get 190.
Fetch the next digit (1) from the dividend, attach it to 190 and continue: 1901 / 863

On to step 7:
When dividing 1901 by 863, we get 2 with a remainder of 175.
Record the quotient 2 as the next digit in the result. 
Result so far: 8362.0
If we subtract 1726 from 1901, we get 175.
Grab the next digit (9) from the dividend, add it to 175, then carry on: 1759 / 863

On to step 8:
863 can be fit into 1759 2 times, resulting in a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 83622.0
Subtracting 1726 from 1759 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
If we divide 330 by 863, we get 0 and a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 83622.0
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 10:
3300 divided by 863 is 3 with a remainder of 711.
Record the quotient 3 as the next digit in the result. 
Result so far: 83622.03
The remainder is 711 after subtracting 2589 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Let's proceed to step 11:
863 goes into 7110 8 times with a remainder of 206.
Write down 8 as next digit of the result. 
Result so far: 83622.038
If we subtract 6904 from 7110, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 12:
2060 divided by 863 is 2 with a remainder of 334.
The number 2 becomes the next digit in our result. 
Result so far: 83622.0382
Subtracting 1726 from 2060 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 13:
When dividing 3340 by 863, we get 3 with a remainder of 751.
The next digit of our result is 3. 
Result so far: 83622.03823
Deduct 2589 from 3340 and we're left with 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Step 14:
863 can be fit into 7510 8 times, resulting in a remainder of 606.
Record the quotient 8 as the next digit in the result. 
Result so far: 83622.038238
If we take 6904 away from 7510, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Moving on to step 15:
863 goes into 6060 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 83622.0382387
The remainder is 19 after subtracting 6041 from 6060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 16:
The number 863 fits into 190 0 times, leaving a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 83622.0382387
If we subtract 0 from 190, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final result is 83622.0382387 with a remainder of 1.9e-07.
