99815781 divided by 331 
We want to figure out the number of times 99815781 can be divided by 331.

Advancing to step 1:
If we divide 9 by 331, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 331

Let's proceed to step 2:
331 can be fit into 99 0 times, resulting in a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 331

Going ahead to step 3:
331 goes into 998 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 5 after subtracting 993 from 998.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 331

Advancing to step 4:
If we divide 51 by 331, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 331

Step 5:
515 divided by 331 is 1 with a remainder of 184.
The next digit of our result is 1. 
Result so far: 301.0
If we subtract 331 from 515, we get 184.
Include the next digit (7) from the dividend after 184, then repeat: 1847 / 331

Let's proceed to step 6:
1847 divided by 331 is 5 with a remainder of 192.
Record the quotient 5 as the next digit in the result. 
Result so far: 3015.0
If we subtract 1655 from 1847, we get 192.
Append the next digit (8) from the dividend to 192 and continue with: 1928 / 331

On to step 7:
1928 divided by 331 is 5 with a remainder of 273.
The number 5 becomes the next digit in our result. 
Result so far: 30155.0
Deduct 1655 from 1928 and we're left with 273.
Include the next digit (1) from the dividend after 273, then repeat: 2731 / 331

Going ahead to step 8:
2731 divided by 331 is 8 with a remainder of 83.
Record the quotient 8 as the next digit in the result. 
Result so far: 301558.0
Subtract 2648 from 2731 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 9:
The number 331 fits into 830 2 times, leaving a remainder of 168.
Put 2 as the next digit of the answer. 
Result so far: 301558.2
Deduct 662 from 830 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 10:
331 can be fit into 1680 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 301558.25
Subtract 1655 from 1680 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
331 goes into 250 0 times with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 301558.25
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 12:
If we divide 2500 by 331, we get 7 and a remainder of 183.
Write down 7 as next digit of the result. 
Result so far: 301558.2507
Deduct 2317 from 2500 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 13:
When dividing 1830 by 331, we get 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 301558.25075
Subtract 1655 from 1830 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 14:
The number 331 fits into 1750 5 times, leaving a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 301558.250755
If we take 1655 away from 1750, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The quotient of the division is 301558.250755, and the remainder is 9.5e-06.
