99905831 divided by 818 
Our goal is to divide 99905831 by 818.

Going ahead to step 1:
When dividing 9 by 818, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 818

Going ahead to step 2:
818 can be fit into 99 0 times, resulting in a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 818

Let's proceed to step 3:
818 can be fit into 999 1 times, resulting in a remainder of 181.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 818 from 999 leaves us with 181.
Grab the next digit (0) from the dividend, add it to 181, then carry on: 1810 / 818

Going ahead to step 4:
When dividing 1810 by 818, we get 2 with a remainder of 174.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 1636 from 1810 and we're left with 174.
Bring next digit (5) of the dividend behind the 174 and repeat the process: 1745 / 818

Advancing to step 5:
1745 divided by 818 is 2 with a remainder of 109.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Subtract 1636 from 1745 to get 109.
Append the next digit (8) from the dividend to 109 and continue with: 1098 / 818

Going ahead to step 6:
1098 divided by 818 is 1 with a remainder of 280.
Write down 1 as next digit of the result. 
Result so far: 1221.0
Subtract 818 from 1098 to get 280.
Include the next digit (3) from the dividend after 280, then repeat: 2803 / 818

On to step 7:
The number 818 fits into 2803 3 times, leaving a remainder of 349.
Write down 3 as next digit of the result. 
Result so far: 12213.0
If we subtract 2454 from 2803, we get 349.
Grab the next digit (1) from the dividend, add it to 349, then carry on: 3491 / 818

Going ahead to step 8:
When dividing 3491 by 818, we get 4 with a remainder of 219.
The number 4 becomes the next digit in our result. 
Result so far: 122134.0
If we subtract 3272 from 3491, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Advancing to step 9:
The number 818 fits into 2190 2 times, leaving a remainder of 554.
Write down 2 as next digit of the result. 
Result so far: 122134.2
Deduct 1636 from 2190 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 10:
818 can be fit into 5540 6 times, resulting in a remainder of 632.
The number 6 becomes the next digit in our result. 
Result so far: 122134.26
Subtract 4908 from 5540 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 11:
The number 818 fits into 6320 7 times, leaving a remainder of 594.
Use 7 as the next digit of our solution. 
Result so far: 122134.267
The remainder is 594 after subtracting 5726 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Advancing to step 12:
818 can be fit into 5940 7 times, resulting in a remainder of 214.
Write down 7 as next digit of the result. 
Result so far: 122134.2677
Deduct 5726 from 5940 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

After the division, we end up with 122134.2677 and a remainder of 0.00214.
