We're dividing 146383 by 20 
We want to figure out the number of times 146383 can be divided by 20.

Let's proceed to step 1:
20 can be fit into 1 0 times, resulting in 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.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 20

On to step 2:
If we divide 14 by 20, 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.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 20

Going ahead to step 3:
The number 20 fits into 146 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 140 from 146, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 20

Going ahead to step 4:
The number 20 fits into 63 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 73.0
Deduct 60 from 63 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 20

On to step 5:
38 divided by 20 is 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 731.0
Deduct 20 from 38 and we're left with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 20

On to step 6:
20 can be fit into 183 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 7319.0
Subtracting 180 from 183 leaves us with 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:
20 can be fit into 30 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 7319.1
Subtracting 20 from 30 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.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 7319.15
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7319.15
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.

Step 10:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7319.15
Subtract 0 from 0 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.

The final outcome is 7319.15, with a leftover of 0.0.
