We look at the division of 18168422 by 243 
Our goal is to divide 18168422 by 243.

Going ahead to step 1:
1 divided by 243 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 243

Let's proceed to step 2:
If we divide 18 by 243, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 243

Moving on to step 3:
The number 243 fits into 181 0 times, leaving a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 181 to get 181.
Append the next digit (6) from the dividend to 181 and continue with: 1816 / 243

Advancing to step 4:
If we divide 1816 by 243, we get 7 and a remainder of 115.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 1701 away from 1816, we end up with 115.
Take the next digit (8) from the dividend and append it to 115, then repeat: 1158 / 243

Step 5:
The number 243 fits into 1158 4 times, leaving a remainder of 186.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Deduct 972 from 1158 and we're left with 186.
Grab the next digit (4) from the dividend, add it to 186, then carry on: 1864 / 243

Step 6:
243 can be fit into 1864 7 times, resulting in a remainder of 163.
The next digit of our result is 7. 
Result so far: 747.0
Deduct 1701 from 1864 and we're left with 163.
Append the next digit (2) from the dividend to 163 and continue with: 1632 / 243

Let's proceed to step 7:
243 goes into 1632 6 times with a remainder of 174.
Record the quotient 6 as the next digit in the result. 
Result so far: 7476.0
If we take 1458 away from 1632, we end up with 174.
Bring next digit (2) of the dividend behind the 174 and repeat the process: 1742 / 243

Advancing to step 8:
243 can be fit into 1742 7 times, resulting in a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 74767.0
The remainder is 41 after subtracting 1701 from 1742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
243 goes into 410 1 times with a remainder of 167.
Use 1 as the next digit of our solution. 
Result so far: 74767.1
The remainder is 167 after subtracting 243 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 10:
When dividing 1670 by 243, we get 6 with a remainder of 212.
Put 6 as the next digit of the answer. 
Result so far: 74767.16
Subtracting 1458 from 1670 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 11:
2120 divided by 243 is 8 with a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 74767.168
If we take 1944 away from 2120, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 12:
243 can be fit into 1760 7 times, resulting in a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 74767.1687
Subtracting 1701 from 1760 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 13:
243 goes into 590 2 times with a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 74767.16872
If we take 486 away from 590, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 14:
The number 243 fits into 1040 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 74767.168724
If we take 972 away from 1040, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 15:
680 divided by 243 is 2 with a remainder of 194.
Write down 2 as next digit of the result. 
Result so far: 74767.1687242
If we subtract 486 from 680, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 16:
The number 243 fits into 1940 7 times, leaving a remainder of 239.
Record the quotient 7 as the next digit in the result. 
Result so far: 74767.16872427
If we take 1701 away from 1940, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

After the division, we end up with 74767.16872427 and a remainder of 2.39e-07.
