76458990 ÷ 30 
We want to divide 76458990 by 30.

On to step 1:
If we divide 7 by 30, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 30

Step 2:
The number 30 fits into 76 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 60 away from 76, we end up with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 30

Moving on to step 3:
30 goes into 164 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 150 from 164, we get 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 30

On to step 4:
If we divide 145 by 30, we get 4 and a remainder of 25.
The next digit of our result is 4. 
Result so far: 254.0
If we subtract 120 from 145, we get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 30

Advancing to step 5:
The number 30 fits into 258 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 2548.0
The remainder is 18 after subtracting 240 from 258.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 30

On to step 6:
189 divided by 30 is 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 25486.0
Subtracting 180 from 189 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 30

Advancing to step 7:
30 can be fit into 99 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 254863.0
Subtract 90 from 99 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 30

Let's proceed to step 8:
The number 30 fits into 90 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 2548633.0
If we take 90 away from 90, we end up 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.

Step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 2548633.0
The remainder is 0 after subtracting 0 from 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 10:
When dividing 0 by 30, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2548633.0
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.

After the division, we end up with 2548633.0 and a remainder of 0.0.
