Let's divide 30121242 by 744
We want to figure out the number of times 30121242 can be divided by 744.

Advancing to step 1:
When dividing 3 by 744, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 744

Step 2:
When dividing 30 by 744, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 744

Step 3:
When dividing 301 by 744, we get 0 with a remainder of 301.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 301 after subtracting 0 from 301.
Take the next digit (2) from the dividend and append it to 301, then repeat: 3012 / 744

Step 4:
3012 divided by 744 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 2976 away from 3012, we end up with 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 744

Going ahead to step 5:
744 can be fit into 361 0 times, resulting in a remainder of 361.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 361 after subtracting 0 from 361.
Include the next digit (2) from the dividend after 361, then repeat: 3612 / 744

On to step 6:
3612 divided by 744 is 4 with a remainder of 636.
Write down 4 as next digit of the result. 
Result so far: 404.0
Deduct 2976 from 3612 and we're left with 636.
Append the next digit (4) from the dividend to 636 and continue with: 6364 / 744

On to step 7:
744 can be fit into 6364 8 times, resulting in a remainder of 412.
The number 8 becomes the next digit in our result. 
Result so far: 4048.0
If we take 5952 away from 6364, we end up with 412.
Grab the next digit (2) from the dividend, add it to 412, then carry on: 4122 / 744

Going ahead to step 8:
744 can be fit into 4122 5 times, resulting in a remainder of 402.
The number 5 becomes the next digit in our result. 
Result so far: 40485.0
Subtracting 3720 from 4122 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 9:
744 goes into 4020 5 times with a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 40485.5
The remainder is 300 after subtracting 3720 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 10:
If we divide 3000 by 744, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 40485.54
If we subtract 2976 from 3000, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
When dividing 240 by 744, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 40485.54
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
744 can be fit into 2400 3 times, resulting in a remainder of 168.
Write down 3 as next digit of the result. 
Result so far: 40485.5403
Deduct 2232 from 2400 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 13:
If we divide 1680 by 744, we get 2 and a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 40485.54032
Deduct 1488 from 1680 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 14:
The number 744 fits into 1920 2 times, leaving a remainder of 432.
Put 2 as the next digit of the answer. 
Result so far: 40485.540322
Subtract 1488 from 1920 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

In conclusion, the division gives 40485.540322 with a balance of 4.32e-05.
