71845905 divided by 30 
We want to figure out the number of times 71845905 can be divided by 30.

Going ahead to step 1:
30 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 30

On to step 2:
The number 30 fits into 71 2 times, leaving a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 60 from 71 and we're left with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 30

Step 3:
If we divide 118 by 30, we get 3 and a remainder of 28.
The next digit of our result is 3. 
Result so far: 23.0
If we take 90 away from 118, we end up with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 30

Moving on to step 4:
30 goes into 284 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
The remainder is 14 after subtracting 270 from 284.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 30

Let's proceed to step 5:
The number 30 fits into 145 4 times, leaving a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 2394.0
Subtracting 120 from 145 leaves us with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 30

Advancing to step 6:
30 goes into 259 8 times with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 23948.0
The remainder is 19 after subtracting 240 from 259.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 30

Advancing to step 7:
30 can be fit into 190 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 239486.0
If we subtract 180 from 190, we get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 30

Step 8:
If we divide 105 by 30, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 2394863.0
If we take 90 away from 105, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
30 goes into 150 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2394863.5
Subtracting 150 from 150 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 30, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 2394863.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 2394863.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2394863.5 with a remainder of 0.0.
