We divide 146253 by 30
We want to figure out the number of times 146253 can be divided by 30.

Step 1:
The number 30 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 30

Step 2:
If we divide 14 by 30, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 30

Advancing to step 3:
If we divide 146 by 30, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 120 from 146 and we're left with 26.
Take the next digit (2) from the dividend and append it to 26, then repeat: 262 / 30

On to step 4:
When dividing 262 by 30, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 240 from 262 and we're left with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 30

Moving on to step 5:
30 goes into 225 7 times with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 487.0
Subtract 210 from 225 to get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 30

On to step 6:
The number 30 fits into 153 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 4875.0
Subtract 150 from 153 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 30 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 4875.1
Subtract 30 from 30 to 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.

Going ahead to step 8:
If we divide 0 by 30, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4875.1
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.

Going ahead to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4875.1
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.

The final outcome is 4875.1, with a leftover of 0.0.
