We look at the division of 221251 by 75 
We want to divide 221251 by 75.

On to step 1:
The number 75 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 75

Let's proceed to step 2:
The number 75 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 75

Going ahead to step 3:
The number 75 fits into 221 2 times, leaving a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 150 from 221, we get 71.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 75

Moving on to step 4:
When dividing 712 by 75, we get 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtracting 675 from 712 leaves us with 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 75

Moving on to step 5:
The number 75 fits into 375 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 295.0
If we take 375 away from 375, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 75

Let's proceed to step 6:
If we divide 1 by 75, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 2950.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 75 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2950.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
75 can be fit into 100 1 times, resulting in a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 2950.01
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.

Let's proceed to step 9:
75 goes into 250 3 times with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 2950.013
If we subtract 225 from 250, 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.

Advancing to step 10:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 2950.0133
If we subtract 225 from 250, 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.

The final result is 2950.0133 with a remainder of 0.00025.
