221522 ÷ 75 
We're looking to find how many times 75 goes into 221522.

Going ahead to step 1:
2 divided by 75 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 75

Let's proceed to step 2:
22 divided by 75 is 0 with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 75

On to step 3:
If we divide 221 by 75, we get 2 and a remainder of 71.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 150 from 221 leaves us with 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 75

Let's proceed to step 4:
When dividing 715 by 75, we get 9 with a remainder of 40.
The next digit of our result is 9. 
Result so far: 29.0
If we subtract 675 from 715, we get 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 75

Going ahead to step 5:
402 divided by 75 is 5 with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 295.0
The remainder is 27 after subtracting 375 from 402.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 75

Going ahead to step 6:
If we divide 272 by 75, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 2953.0
If we take 225 away from 272, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
470 divided by 75 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 2953.6
Deduct 450 from 470 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 75, we get 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 2953.62
Subtracting 150 from 200 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 2953.626
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 2953.6266
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 2953.6266 with a remainder of 0.0005.
