147790 divided by 30 
We want to figure out the number of times 147790 can be divided by 30.

Going ahead to step 1:
1 divided by 30 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 30

Advancing to step 2:
If we divide 14 by 30, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 30

On to step 3:
30 goes into 147 4 times with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 120 from 147 leaves us with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 30

On to step 4:
When dividing 277 by 30, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 49.0
The remainder is 7 after subtracting 270 from 277.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 30

Let's proceed to step 5:
The number 30 fits into 79 2 times, leaving a remainder of 19.
The next digit of our result is 2. 
Result so far: 492.0
If we take 60 away from 79, we end up with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 30

Going ahead to step 6:
If we divide 190 by 30, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 4926.0
If we take 180 away from 190, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
30 goes into 100 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 4926.3
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 4926.33
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 4926.33, with a leftover of 0.01.
