Let's divide 18190943 by 818
Our goal is to divide 18190943 by 818.

On to step 1:
When dividing 1 by 818, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 818

Step 2:
The number 818 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 818

Let's proceed to step 3:
If we divide 181 by 818, we get 0 and a remainder of 181.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 181, we end up with 181.
Fetch the next digit (9) from the dividend, attach it to 181 and continue: 1819 / 818

Let's proceed to step 4:
1819 divided by 818 is 2 with a remainder of 183.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 183 after subtracting 1636 from 1819.
Take the next digit (0) from the dividend and append it to 183, then repeat: 1830 / 818

Going ahead to step 5:
818 can be fit into 1830 2 times, resulting in a remainder of 194.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 194 after subtracting 1636 from 1830.
Grab the next digit (9) from the dividend, add it to 194, then carry on: 1949 / 818

Advancing to step 6:
When dividing 1949 by 818, we get 2 with a remainder of 313.
The number 2 becomes the next digit in our result. 
Result so far: 222.0
Deduct 1636 from 1949 and we're left with 313.
Include the next digit (4) from the dividend after 313, then repeat: 3134 / 818

Going ahead to step 7:
When dividing 3134 by 818, we get 3 with a remainder of 680.
Record the quotient 3 as the next digit in the result. 
Result so far: 2223.0
Deduct 2454 from 3134 and we're left with 680.
Append the next digit (3) from the dividend to 680 and continue with: 6803 / 818

Advancing to step 8:
6803 divided by 818 is 8 with a remainder of 259.
The next digit of our result is 8. 
Result so far: 22238.0
Deduct 6544 from 6803 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Let's proceed to step 9:
The number 818 fits into 2590 3 times, leaving a remainder of 136.
The number 3 becomes the next digit in our result. 
Result so far: 22238.3
If we take 2454 away from 2590, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 10:
818 goes into 1360 1 times with a remainder of 542.
Record the quotient 1 as the next digit in the result. 
Result so far: 22238.31
Deduct 818 from 1360 and we're left with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

On to step 11:
818 can be fit into 5420 6 times, resulting in a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 22238.316
Deduct 4908 from 5420 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 12:
5120 divided by 818 is 6 with a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 22238.3166
Subtract 4908 from 5120 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final result is 22238.3166 with a remainder of 0.00212.
