Let's divide 18909145 by 242
Our goal is to divide 18909145 by 242.

On to step 1:
242 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 242

On to step 2:
The number 242 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 242

Step 3:
If we divide 189 by 242, we get 0 and a remainder of 189.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 189, we get 189.
Take the next digit (0) from the dividend and append it to 189, then repeat: 1890 / 242

Advancing to step 4:
242 can be fit into 1890 7 times, resulting in a remainder of 196.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 196 after subtracting 1694 from 1890.
Bring next digit (9) of the dividend behind the 196 and repeat the process: 1969 / 242

On to step 5:
The number 242 fits into 1969 8 times, leaving a remainder of 33.
The next digit of our result is 8. 
Result so far: 78.0
Subtract 1936 from 1969 to get 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 242

Step 6:
242 can be fit into 331 1 times, resulting in a remainder of 89.
The next digit of our result is 1. 
Result so far: 781.0
Deduct 242 from 331 and we're left with 89.
Append the next digit (4) from the dividend to 89 and continue with: 894 / 242

Going ahead to step 7:
When dividing 894 by 242, we get 3 with a remainder of 168.
Put 3 as the next digit of the answer. 
Result so far: 7813.0
Deduct 726 from 894 and we're left with 168.
Take the next digit (5) from the dividend and append it to 168, then repeat: 1685 / 242

Going ahead to step 8:
242 can be fit into 1685 6 times, resulting in a remainder of 233.
Record the quotient 6 as the next digit in the result. 
Result so far: 78136.0
Deduct 1452 from 1685 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 9:
When dividing 2330 by 242, we get 9 with a remainder of 152.
The next digit of our result is 9. 
Result so far: 78136.9
If we take 2178 away from 2330, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 10:
242 can be fit into 1520 6 times, resulting in a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 78136.96
If we take 1452 away from 1520, 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 11:
The number 242 fits into 680 2 times, leaving a remainder of 196.
The number 2 becomes the next digit in our result. 
Result so far: 78136.962
The remainder is 196 after subtracting 484 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 12:
1960 divided by 242 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 78136.9628
Deduct 1936 from 1960 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
242 can be fit into 240 0 times, resulting in a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 78136.9628
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 14:
242 goes into 2400 9 times with a remainder of 222.
Record the quotient 9 as the next digit in the result. 
Result so far: 78136.962809
If we take 2178 away from 2400, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 15:
When dividing 2220 by 242, we get 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 78136.9628099
Deduct 2178 from 2220 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 78136.9628099 with a balance of 4.2e-07.
