We're dividing 99369616 by 863 
Our goal is to divide 99369616 by 863.

Let's proceed to step 1:
863 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 863

Going ahead to step 2:
If we divide 99 by 863, we get 0 and a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (3) from the dividend and append it to 99, then repeat: 993 / 863

Moving on to step 3:
The number 863 fits into 993 1 times, leaving a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 863 away from 993, we end up with 130.
Append the next digit (6) from the dividend to 130 and continue with: 1306 / 863

Let's proceed to step 4:
The number 863 fits into 1306 1 times, leaving a remainder of 443.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 863 from 1306, we get 443.
Grab the next digit (9) from the dividend, add it to 443, then carry on: 4439 / 863

Advancing to step 5:
If we divide 4439 by 863, we get 5 and a remainder of 124.
The next digit of our result is 5. 
Result so far: 115.0
If we take 4315 away from 4439, we end up with 124.
Take the next digit (6) from the dividend and append it to 124, then repeat: 1246 / 863

Advancing to step 6:
The number 863 fits into 1246 1 times, leaving a remainder of 383.
Use 1 as the next digit of our solution. 
Result so far: 1151.0
Subtract 863 from 1246 to get 383.
Append the next digit (1) from the dividend to 383 and continue with: 3831 / 863

Moving on to step 7:
863 can be fit into 3831 4 times, resulting in a remainder of 379.
Use 4 as the next digit of our solution. 
Result so far: 11514.0
Deduct 3452 from 3831 and we're left with 379.
Append the next digit (6) from the dividend to 379 and continue with: 3796 / 863

Moving on to step 8:
863 goes into 3796 4 times with a remainder of 344.
The number 4 becomes the next digit in our result. 
Result so far: 115144.0
Subtract 3452 from 3796 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 9:
3440 divided by 863 is 3 with a remainder of 851.
Record the quotient 3 as the next digit in the result. 
Result so far: 115144.3
Deduct 2589 from 3440 and we're left with 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Let's proceed to step 10:
8510 divided by 863 is 9 with a remainder of 743.
The number 9 becomes the next digit in our result. 
Result so far: 115144.39
The remainder is 743 after subtracting 7767 from 8510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Moving on to step 11:
863 goes into 7430 8 times with a remainder of 526.
The next digit of our result is 8. 
Result so far: 115144.398
If we subtract 6904 from 7430, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Moving on to step 12:
5260 divided by 863 is 6 with a remainder of 82.
Put 6 as the next digit of the answer. 
Result so far: 115144.3986
Deduct 5178 from 5260 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 13:
The number 863 fits into 820 0 times, leaving a remainder of 820.
Use 0 as the next digit of our solution. 
Result so far: 115144.3986
Subtracting 0 from 820 leaves us with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 14:
When dividing 8200 by 863, we get 9 with a remainder of 433.
The next digit of our result is 9. 
Result so far: 115144.398609
If we subtract 7767 from 8200, we get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Step 15:
If we divide 4330 by 863, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 115144.3986095
Deduct 4315 from 4330 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 16:
If we divide 150 by 863, we get 0 and a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 115144.3986095
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final outcome is 115144.3986095, with a leftover of 1.5e-07.
