Let's divide 405818 by 99
We're looking to find how many times 99 goes into 405818.

Moving on to step 1:
99 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 99

Let's proceed to step 2:
99 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 99

Step 3:
When dividing 405 by 99, we get 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 396 from 405 leaves us with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 99

Advancing to step 4:
When dividing 98 by 99, we get 0 with a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 98, we end up with 98.
Append the next digit (1) from the dividend to 98 and continue with: 981 / 99

On to step 5:
99 can be fit into 981 9 times, resulting in a remainder of 90.
Put 9 as the next digit of the answer. 
Result so far: 409.0
If we subtract 891 from 981, we get 90.
Bring next digit (8) of the dividend behind the 90 and repeat the process: 908 / 99

On to step 6:
99 can be fit into 908 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 4099.0
If we take 891 away from 908, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
If we divide 170 by 99, we get 1 and a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 4099.1
If we take 99 away from 170, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 8:
If we divide 710 by 99, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 4099.17
Deduct 693 from 710 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
The number 99 fits into 170 1 times, leaving a remainder of 71.
The next digit of our result is 1. 
Result so far: 4099.171
If we take 99 away from 170, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 10:
710 divided by 99 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 4099.1717
If we take 693 away from 710, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
The number 99 fits into 170 1 times, leaving a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 4099.17171
If we take 99 away from 170, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
99 goes into 710 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 4099.171717
If we subtract 693 from 710, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 13:
99 goes into 170 1 times with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 4099.1717171
Subtracting 99 from 170 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 14:
99 goes into 710 7 times with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 4099.17171717
Deduct 693 from 710 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 4099.17171717 and a remainder of 1.7e-08.
