30042558 ÷ 109 
We want to figure out the number of times 30042558 can be divided by 109.

Advancing to step 1:
3 divided by 109 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 109

Advancing to step 2:
If we divide 30 by 109, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 109

Advancing to step 3:
When dividing 300 by 109, we get 2 with a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 218 away from 300, we end up with 82.
Include the next digit (4) from the dividend after 82, then repeat: 824 / 109

On to step 4:
109 can be fit into 824 7 times, resulting in a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 27.0
The remainder is 61 after subtracting 763 from 824.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 109

On to step 5:
612 divided by 109 is 5 with a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 275.0
Subtract 545 from 612 to get 67.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 109

Going ahead to step 6:
If we divide 675 by 109, we get 6 and a remainder of 21.
The next digit of our result is 6. 
Result so far: 2756.0
Deduct 654 from 675 and we're left with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 109

Advancing to step 7:
109 goes into 215 1 times with a remainder of 106.
The next digit of our result is 1. 
Result so far: 27561.0
Subtracting 109 from 215 leaves us with 106.
Take the next digit (8) from the dividend and append it to 106, then repeat: 1068 / 109

Moving on to step 8:
If we divide 1068 by 109, we get 9 and a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 275619.0
If we take 981 away from 1068, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 9:
109 goes into 870 7 times with a remainder of 107.
The number 7 becomes the next digit in our result. 
Result so far: 275619.7
If we subtract 763 from 870, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 10:
When dividing 1070 by 109, we get 9 with a remainder of 89.
Record the quotient 9 as the next digit in the result. 
Result so far: 275619.79
Deduct 981 from 1070 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 11:
890 divided by 109 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 275619.798
Deduct 872 from 890 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
109 can be fit into 180 1 times, resulting in a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 275619.7981
The remainder is 71 after subtracting 109 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 13:
109 goes into 710 6 times with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 275619.79816
The remainder is 56 after subtracting 654 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
When dividing 560 by 109, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 275619.798165
The remainder is 15 after subtracting 545 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 15:
The number 109 fits into 150 1 times, leaving a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 275619.7981651
If we take 109 away from 150, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 16:
109 can be fit into 410 3 times, resulting in a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 275619.79816513
If we subtract 327 from 410, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final outcome is 275619.79816513, with a leftover of 8.3e-08.
