We're dividing 99642490 by 242 
Let's see how many times 242 fits into 99642490.

Step 1:
When dividing 9 by 242, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 242

On to step 2:
99 divided by 242 is 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Append the next digit (6) from the dividend to 99 and continue with: 996 / 242

Step 3:
242 can be fit into 996 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 4.0
If we take 968 away from 996, we end up with 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 242

Moving on to step 4:
242 goes into 284 1 times with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 242 from 284 leaves us with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 242

Moving on to step 5:
The number 242 fits into 422 1 times, leaving a remainder of 180.
The next digit of our result is 1. 
Result so far: 411.0
Deduct 242 from 422 and we're left with 180.
Bring next digit (4) of the dividend behind the 180 and repeat the process: 1804 / 242

Let's proceed to step 6:
The number 242 fits into 1804 7 times, leaving a remainder of 110.
Put 7 as the next digit of the answer. 
Result so far: 4117.0
The remainder is 110 after subtracting 1694 from 1804.
Take the next digit (9) from the dividend and append it to 110, then repeat: 1109 / 242

Going ahead to step 7:
242 can be fit into 1109 4 times, resulting in a remainder of 141.
Record the quotient 4 as the next digit in the result. 
Result so far: 41174.0
The remainder is 141 after subtracting 968 from 1109.
Take the next digit (0) from the dividend and append it to 141, then repeat: 1410 / 242

On to step 8:
242 can be fit into 1410 5 times, resulting in a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 411745.0
Subtract 1210 from 1410 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 9:
2000 divided by 242 is 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 411745.8
Deduct 1936 from 2000 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
If we divide 640 by 242, we get 2 and a remainder of 156.
Record the quotient 2 as the next digit in the result. 
Result so far: 411745.82
The remainder is 156 after subtracting 484 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
1560 divided by 242 is 6 with a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 411745.826
If we subtract 1452 from 1560, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 12:
242 can be fit into 1080 4 times, resulting in a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 411745.8264
If we subtract 968 from 1080, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 13:
If we divide 1120 by 242, we get 4 and a remainder of 152.
The next digit of our result is 4. 
Result so far: 411745.82644
The remainder is 152 after subtracting 968 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

In conclusion, the division gives 411745.82644 with a balance of 0.000152.
