Let's divide 30120756 by 361
We want to figure out the number of times 30120756 can be divided by 361.

On to step 1:
The number 361 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 361

Step 2:
When dividing 30 by 361, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 361

Going ahead to step 3:
301 divided by 361 is 0 with a remainder of 301.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 301, we get 301.
Fetch the next digit (2) from the dividend, attach it to 301 and continue: 3012 / 361

Going ahead to step 4:
The number 361 fits into 3012 8 times, leaving a remainder of 124.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 2888 from 3012 leaves us with 124.
Append the next digit (0) from the dividend to 124 and continue with: 1240 / 361

Going ahead to step 5:
1240 divided by 361 is 3 with a remainder of 157.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we subtract 1083 from 1240, we get 157.
Include the next digit (7) from the dividend after 157, then repeat: 1577 / 361

On to step 6:
361 goes into 1577 4 times with a remainder of 133.
The number 4 becomes the next digit in our result. 
Result so far: 834.0
If we subtract 1444 from 1577, we get 133.
Include the next digit (5) from the dividend after 133, then repeat: 1335 / 361

Moving on to step 7:
361 can be fit into 1335 3 times, resulting in a remainder of 252.
The next digit of our result is 3. 
Result so far: 8343.0
Subtracting 1083 from 1335 leaves us with 252.
Fetch the next digit (6) from the dividend, attach it to 252 and continue: 2526 / 361

Let's proceed to step 8:
361 goes into 2526 6 times with a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 83436.0
Subtract 2166 from 2526 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 9:
When dividing 3600 by 361, we get 9 with a remainder of 351.
The next digit of our result is 9. 
Result so far: 83436.9
The remainder is 351 after subtracting 3249 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Going ahead to step 10:
The number 361 fits into 3510 9 times, leaving a remainder of 261.
Use 9 as the next digit of our solution. 
Result so far: 83436.99
Subtract 3249 from 3510 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

After the division, we end up with 83436.99 and a remainder of 0.261.
