Let's divide 81221930 by 75
We want to figure out the number of times 81221930 can be divided by 75.

Moving on to step 1:
If we divide 8 by 75, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 75

Step 2:
75 can be fit into 81 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 75 from 81 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 75

Let's proceed to step 3:
75 can be fit into 62 0 times, resulting in a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 62 after subtracting 0 from 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 75

Step 4:
The number 75 fits into 622 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 108.0
Deduct 600 from 622 and we're left with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 75

Going ahead to step 5:
The number 75 fits into 221 2 times, leaving a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 1082.0
The remainder is 71 after subtracting 150 from 221.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 75

Step 6:
719 divided by 75 is 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 10829.0
If we take 675 away from 719, we end up with 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 75

Step 7:
The number 75 fits into 443 5 times, leaving a remainder of 68.
The number 5 becomes the next digit in our result. 
Result so far: 108295.0
Subtract 375 from 443 to get 68.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 75

Let's proceed to step 8:
When dividing 680 by 75, we get 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 1082959.0
Subtract 675 from 680 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
50 divided by 75 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 1082959.0
Subtract 0 from 50 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 goes into 500 6 times with a remainder of 50.
The next digit of our result is 6. 
Result so far: 1082959.06
Deduct 450 from 500 and we're left 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.

Moving on to step 11:
75 goes into 500 6 times with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 1082959.066
Subtracting 450 from 500 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.

The final outcome is 1082959.066, with a leftover of 0.005.
