We're dividing 28191221 by 775 
We're looking to find how many times 775 goes into 28191221.

Going ahead to step 1:
2 divided by 775 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 775

On to step 2:
775 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 775

Advancing to step 3:
When dividing 281 by 775, we get 0 with a remainder of 281.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 281 and we're left with 281.
Bring next digit (9) of the dividend behind the 281 and repeat the process: 2819 / 775

Moving on to step 4:
If we divide 2819 by 775, we get 3 and a remainder of 494.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 2325 from 2819 leaves us with 494.
Bring next digit (1) of the dividend behind the 494 and repeat the process: 4941 / 775

On to step 5:
If we divide 4941 by 775, we get 6 and a remainder of 291.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we subtract 4650 from 4941, we get 291.
Grab the next digit (2) from the dividend, add it to 291, then carry on: 2912 / 775

Let's proceed to step 6:
If we divide 2912 by 775, we get 3 and a remainder of 587.
Put 3 as the next digit of the answer. 
Result so far: 363.0
Subtracting 2325 from 2912 leaves us with 587.
Bring next digit (2) of the dividend behind the 587 and repeat the process: 5872 / 775

Moving on to step 7:
5872 divided by 775 is 7 with a remainder of 447.
The number 7 becomes the next digit in our result. 
Result so far: 3637.0
If we subtract 5425 from 5872, we get 447.
Fetch the next digit (1) from the dividend, attach it to 447 and continue: 4471 / 775

Moving on to step 8:
775 can be fit into 4471 5 times, resulting in a remainder of 596.
Write down 5 as next digit of the result. 
Result so far: 36375.0
The remainder is 596 after subtracting 3875 from 4471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 9:
775 can be fit into 5960 7 times, resulting in a remainder of 535.
The next digit of our result is 7. 
Result so far: 36375.7
Deduct 5425 from 5960 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 10:
775 can be fit into 5350 6 times, resulting in a remainder of 700.
Record the quotient 6 as the next digit in the result. 
Result so far: 36375.76
If we take 4650 away from 5350, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 11:
7000 divided by 775 is 9 with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 36375.769
Subtract 6975 from 7000 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.

Moving on to step 12:
When dividing 250 by 775, we get 0 with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 36375.769
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
The number 775 fits into 2500 3 times, leaving a remainder of 175.
The next digit of our result is 3. 
Result so far: 36375.76903
The remainder is 175 after subtracting 2325 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 14:
775 can be fit into 1750 2 times, resulting in a remainder of 200.
The number 2 becomes the next digit in our result. 
Result so far: 36375.769032
If we take 1550 away from 1750, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 15:
When dividing 2000 by 775, we get 2 with a remainder of 450.
The number 2 becomes the next digit in our result. 
Result so far: 36375.7690322
The remainder is 450 after subtracting 1550 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

After the division, we end up with 36375.7690322 and a remainder of 4.5e-06.
