Let's divide 98886787 by 813
Our goal is to divide 98886787 by 813.

Going ahead to step 1:
9 divided by 813 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 813

Advancing to step 2:
When dividing 98 by 813, we get 0 with a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Bring next digit (8) of the dividend behind the 98 and repeat the process: 988 / 813

Moving on to step 3:
If we divide 988 by 813, we get 1 and a remainder of 175.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 175 after subtracting 813 from 988.
Grab the next digit (8) from the dividend, add it to 175, then carry on: 1758 / 813

On to step 4:
813 goes into 1758 2 times with a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1626 from 1758, we get 132.
Include the next digit (6) from the dividend after 132, then repeat: 1326 / 813

On to step 5:
1326 divided by 813 is 1 with a remainder of 513.
The next digit of our result is 1. 
Result so far: 121.0
The remainder is 513 after subtracting 813 from 1326.
Bring next digit (7) of the dividend behind the 513 and repeat the process: 5137 / 813

Let's proceed to step 6:
If we divide 5137 by 813, we get 6 and a remainder of 259.
The number 6 becomes the next digit in our result. 
Result so far: 1216.0
Subtract 4878 from 5137 to get 259.
Append the next digit (8) from the dividend to 259 and continue with: 2598 / 813

Moving on to step 7:
813 can be fit into 2598 3 times, resulting in a remainder of 159.
The next digit of our result is 3. 
Result so far: 12163.0
The remainder is 159 after subtracting 2439 from 2598.
Bring next digit (7) of the dividend behind the 159 and repeat the process: 1597 / 813

Advancing to step 8:
When dividing 1597 by 813, we get 1 with a remainder of 784.
The next digit of our result is 1. 
Result so far: 121631.0
If we take 813 away from 1597, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Moving on to step 9:
7840 divided by 813 is 9 with a remainder of 523.
Record the quotient 9 as the next digit in the result. 
Result so far: 121631.9
If we subtract 7317 from 7840, we get 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Step 10:
813 can be fit into 5230 6 times, resulting in a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 121631.96
Subtracting 4878 from 5230 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 11:
If we divide 3520 by 813, we get 4 and a remainder of 268.
The number 4 becomes the next digit in our result. 
Result so far: 121631.964
Deduct 3252 from 3520 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 12:
813 goes into 2680 3 times with a remainder of 241.
The next digit of our result is 3. 
Result so far: 121631.9643
Subtract 2439 from 2680 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 13:
813 can be fit into 2410 2 times, resulting in a remainder of 784.
The next digit of our result is 2. 
Result so far: 121631.96432
If we subtract 1626 from 2410, we get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

On to step 14:
The number 813 fits into 7840 9 times, leaving a remainder of 523.
The number 9 becomes the next digit in our result. 
Result so far: 121631.964329
Subtracting 7317 from 7840 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Advancing to step 15:
5230 divided by 813 is 6 with a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 121631.9643296
If we subtract 4878 from 5230, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 16:
If we divide 3520 by 813, we get 4 and a remainder of 268.
The next digit of our result is 4. 
Result so far: 121631.96432964
The remainder is 268 after subtracting 3252 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final result is 121631.96432964 with a remainder of 2.68e-07.
