We're dividing 147391 by 75 
We want to figure out the number of times 147391 can be divided by 75.

On to step 1:
75 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 75

Let's proceed to step 2:
14 divided by 75 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 75

Going ahead to step 3:
147 divided by 75 is 1 with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 75 from 147 to get 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 75

Let's proceed to step 4:
When dividing 723 by 75, we get 9 with a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 675 away from 723, we end up with 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 75

On to step 5:
75 can be fit into 489 6 times, resulting in a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
If we subtract 450 from 489, we get 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 75

Let's proceed to step 6:
If we divide 391 by 75, we get 5 and a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 1965.0
Subtracting 375 from 391 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
75 goes into 160 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 1965.2
The remainder is 10 after subtracting 150 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
75 can be fit into 100 1 times, resulting in a remainder of 25.
The next digit of our result is 1. 
Result so far: 1965.21
If we subtract 75 from 100, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
The next digit of our result is 3. 
Result so far: 1965.213
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 1965.2133
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 1965.2133 with a remainder of 0.00025.
