We look at the division of 15828851 by 775 
We want to figure out the number of times 15828851 can be divided by 775.

Going ahead to step 1:
The number 775 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 775

On to step 2:
When dividing 15 by 775, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 775

Let's proceed to step 3:
When dividing 158 by 775, we get 0 with a remainder of 158.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 158 to get 158.
Take the next digit (2) from the dividend and append it to 158, then repeat: 1582 / 775

Moving on to step 4:
The number 775 fits into 1582 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1550 away from 1582, we end up with 32.
Append the next digit (8) from the dividend to 32 and continue with: 328 / 775

Advancing to step 5:
The number 775 fits into 328 0 times, leaving a remainder of 328.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 328, we get 328.
Include the next digit (8) from the dividend after 328, then repeat: 3288 / 775

Let's proceed to step 6:
The number 775 fits into 3288 4 times, leaving a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 204.0
Subtracting 3100 from 3288 leaves us with 188.
Append the next digit (5) from the dividend to 188 and continue with: 1885 / 775

Moving on to step 7:
If we divide 1885 by 775, we get 2 and a remainder of 335.
Put 2 as the next digit of the answer. 
Result so far: 2042.0
If we subtract 1550 from 1885, we get 335.
Bring next digit (1) of the dividend behind the 335 and repeat the process: 3351 / 775

Advancing to step 8:
3351 divided by 775 is 4 with a remainder of 251.
Put 4 as the next digit of the answer. 
Result so far: 20424.0
If we subtract 3100 from 3351, we get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 9:
If we divide 2510 by 775, we get 3 and a remainder of 185.
The next digit of our result is 3. 
Result so far: 20424.3
Subtract 2325 from 2510 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 10:
1850 divided by 775 is 2 with a remainder of 300.
Use 2 as the next digit of our solution. 
Result so far: 20424.32
Deduct 1550 from 1850 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 11:
3000 divided by 775 is 3 with a remainder of 675.
The number 3 becomes the next digit in our result. 
Result so far: 20424.323
The remainder is 675 after subtracting 2325 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Advancing to step 12:
775 can be fit into 6750 8 times, resulting in a remainder of 550.
The next digit of our result is 8. 
Result so far: 20424.3238
Deduct 6200 from 6750 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 13:
If we divide 5500 by 775, we get 7 and a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 20424.32387
Subtracting 5425 from 5500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
775 can be fit into 750 0 times, resulting in a remainder of 750.
Record the quotient 0 as the next digit in the result. 
Result so far: 20424.32387
Subtract 0 from 750 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 15:
When dividing 7500 by 775, we get 9 with a remainder of 525.
Record the quotient 9 as the next digit in the result. 
Result so far: 20424.3238709
Subtracting 6975 from 7500 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Step 16:
5250 divided by 775 is 6 with a remainder of 600.
Record the quotient 6 as the next digit in the result. 
Result so far: 20424.32387096
If we subtract 4650 from 5250, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 20424.32387096 with a remaining 6e-07.
