221857 ÷ 75 
We're looking to find how many times 75 goes into 221857.

Going ahead to step 1:
2 divided by 75 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 75

On to step 2:
If we divide 22 by 75, we get 0 and a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 75

Advancing to step 3:
221 divided by 75 is 2 with a remainder of 71.
Use 2 as the next digit of our solution. 
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:
If we divide 718 by 75, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 29.0
The remainder is 43 after subtracting 675 from 718.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 75

Moving on to step 5:
75 goes into 435 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 295.0
Subtracting 375 from 435 leaves us with 60.
Append the next digit (7) from the dividend to 60 and continue with: 607 / 75

Let's proceed to step 6:
607 divided by 75 is 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 2958.0
Subtracting 600 from 607 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
75 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 2958.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
If we divide 700 by 75, we get 9 and a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 2958.09
If we subtract 675 from 700, 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:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 2958.093
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:
250 divided by 75 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 2958.0933
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 2958.0933 with a remaining 0.00025.
