We're dividing 221859 by 75 
We want to figure out the number of times 221859 can be divided by 75.

Advancing to step 1:
If we divide 2 by 75, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 75

Step 2:
The number 75 fits into 22 0 times, leaving a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 75

On to step 3:
221 divided by 75 is 2 with a remainder of 71.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 150 from 221, we get 71.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 75

On to step 4:
718 divided by 75 is 9 with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we subtract 675 from 718, we get 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 75

On to step 5:
435 divided by 75 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 295.0
If we take 375 away from 435, we end up with 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 75

Let's proceed to step 6:
609 divided by 75 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 2958.0
Deduct 600 from 609 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 75, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 2958.1
The remainder is 15 after subtracting 75 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
75 can be fit into 150 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2958.12
The remainder is 0 after subtracting 150 from 150.
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:
When dividing 0 by 75, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2958.12
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.

Step 10:
0 divided by 75 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2958.12
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.

The final outcome is 2958.12, with a leftover of 0.0.
