Let's divide 78642097 by 775
We want to divide 78642097 by 775.

Step 1:
775 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 775

Moving on to step 2:
If we divide 78 by 775, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 775

Moving on to step 3:
The number 775 fits into 786 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 775 from 786, we get 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 775

Step 4:
114 divided by 775 is 0 with a remainder of 114.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 114 after subtracting 0 from 114.
Append the next digit (2) from the dividend to 114 and continue with: 1142 / 775

Advancing to step 5:
1142 divided by 775 is 1 with a remainder of 367.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
If we take 775 away from 1142, we end up with 367.
Bring next digit (0) of the dividend behind the 367 and repeat the process: 3670 / 775

Step 6:
The number 775 fits into 3670 4 times, leaving a remainder of 570.
Write down 4 as next digit of the result. 
Result so far: 1014.0
Subtract 3100 from 3670 to get 570.
Include the next digit (9) from the dividend after 570, then repeat: 5709 / 775

Let's proceed to step 7:
The number 775 fits into 5709 7 times, leaving a remainder of 284.
Record the quotient 7 as the next digit in the result. 
Result so far: 10147.0
Deduct 5425 from 5709 and we're left with 284.
Include the next digit (7) from the dividend after 284, then repeat: 2847 / 775

On to step 8:
775 goes into 2847 3 times with a remainder of 522.
Write down 3 as next digit of the result. 
Result so far: 101473.0
Subtract 2325 from 2847 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 9:
The number 775 fits into 5220 6 times, leaving a remainder of 570.
Use 6 as the next digit of our solution. 
Result so far: 101473.6
Deduct 4650 from 5220 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 10:
775 can be fit into 5700 7 times, resulting in a remainder of 275.
Write down 7 as next digit of the result. 
Result so far: 101473.67
Deduct 5425 from 5700 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 11:
If we divide 2750 by 775, we get 3 and a remainder of 425.
Write down 3 as next digit of the result. 
Result so far: 101473.673
If we subtract 2325 from 2750, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 12:
If we divide 4250 by 775, we get 5 and a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 101473.6735
If we subtract 3875 from 4250, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 13:
3750 divided by 775 is 4 with a remainder of 650.
Record the quotient 4 as the next digit in the result. 
Result so far: 101473.67354
The remainder is 650 after subtracting 3100 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 14:
The number 775 fits into 6500 8 times, leaving a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 101473.673548
If we subtract 6200 from 6500, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 15:
775 can be fit into 3000 3 times, resulting in a remainder of 675.
Put 3 as the next digit of the answer. 
Result so far: 101473.6735483
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.

Step 16:
If we divide 6750 by 775, we get 8 and a remainder of 550.
The next digit of our result is 8. 
Result so far: 101473.67354838
Subtracting 6200 from 6750 leaves us 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.

In conclusion, the division gives 101473.67354838 with a balance of 5.5e-07.
