86867096 ÷ 663 
Our goal is to divide 86867096 by 663.

Going ahead to step 1:
If we divide 8 by 663, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 663

Step 2:
663 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 663

Let's proceed to step 3:
663 can be fit into 868 1 times, resulting in a remainder of 205.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 663 from 868, we get 205.
Take the next digit (6) from the dividend and append it to 205, then repeat: 2056 / 663

Step 4:
The number 663 fits into 2056 3 times, leaving a remainder of 67.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1989 from 2056, we get 67.
Take the next digit (7) from the dividend and append it to 67, then repeat: 677 / 663

Advancing to step 5:
If we divide 677 by 663, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 131.0
If we subtract 663 from 677, we get 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 663

Advancing to step 6:
When dividing 140 by 663, we get 0 with a remainder of 140.
The next digit of our result is 0. 
Result so far: 1310.0
Subtracting 0 from 140 leaves us with 140.
Bring next digit (9) of the dividend behind the 140 and repeat the process: 1409 / 663

Let's proceed to step 7:
1409 divided by 663 is 2 with a remainder of 83.
Use 2 as the next digit of our solution. 
Result so far: 13102.0
The remainder is 83 after subtracting 1326 from 1409.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 663

Advancing to step 8:
836 divided by 663 is 1 with a remainder of 173.
The next digit of our result is 1. 
Result so far: 131021.0
The remainder is 173 after subtracting 663 from 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 9:
663 can be fit into 1730 2 times, resulting in a remainder of 404.
Use 2 as the next digit of our solution. 
Result so far: 131021.2
Subtracting 1326 from 1730 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 10:
If we divide 4040 by 663, we get 6 and a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 131021.26
Subtract 3978 from 4040 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
663 goes into 620 0 times with a remainder of 620.
The number 0 becomes the next digit in our result. 
Result so far: 131021.26
The remainder is 620 after subtracting 0 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 12:
If we divide 6200 by 663, we get 9 and a remainder of 233.
Write down 9 as next digit of the result. 
Result so far: 131021.2609
If we subtract 5967 from 6200, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 13:
663 can be fit into 2330 3 times, resulting in a remainder of 341.
The next digit of our result is 3. 
Result so far: 131021.26093
Subtract 1989 from 2330 to get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 14:
If we divide 3410 by 663, we get 5 and a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 131021.260935
Subtract 3315 from 3410 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 15:
663 goes into 950 1 times with a remainder of 287.
Record the quotient 1 as the next digit in the result. 
Result so far: 131021.2609351
If we take 663 away from 950, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 16:
2870 divided by 663 is 4 with a remainder of 218.
Use 4 as the next digit of our solution. 
Result so far: 131021.26093514
The remainder is 218 after subtracting 2652 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Our division results in 131021.26093514 with a remaining 2.18e-07.
