81773488 ÷ 397 
Let's see how many times 397 fits into 81773488.

Step 1:
If we divide 8 by 397, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 397

Advancing to step 2:
81 divided by 397 is 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 397

Moving on to step 3:
397 can be fit into 817 2 times, resulting in a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 794 from 817 leaves us with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 397

Step 4:
If we divide 237 by 397, we get 0 and a remainder of 237.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 237, we get 237.
Bring next digit (3) of the dividend behind the 237 and repeat the process: 2373 / 397

Let's proceed to step 5:
When dividing 2373 by 397, we get 5 with a remainder of 388.
The next digit of our result is 5. 
Result so far: 205.0
Subtract 1985 from 2373 to get 388.
Bring next digit (4) of the dividend behind the 388 and repeat the process: 3884 / 397

Going ahead to step 6:
3884 divided by 397 is 9 with a remainder of 311.
The next digit of our result is 9. 
Result so far: 2059.0
Subtracting 3573 from 3884 leaves us with 311.
Take the next digit (8) from the dividend and append it to 311, then repeat: 3118 / 397

Step 7:
397 can be fit into 3118 7 times, resulting in a remainder of 339.
Write down 7 as next digit of the result. 
Result so far: 20597.0
Deduct 2779 from 3118 and we're left with 339.
Include the next digit (8) from the dividend after 339, then repeat: 3398 / 397

Going ahead to step 8:
397 can be fit into 3398 8 times, resulting in a remainder of 222.
Use 8 as the next digit of our solution. 
Result so far: 205978.0
The remainder is 222 after subtracting 3176 from 3398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 9:
397 can be fit into 2220 5 times, resulting in a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 205978.5
If we subtract 1985 from 2220, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 10:
If we divide 2350 by 397, we get 5 and a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 205978.55
Subtract 1985 from 2350 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

The final result is 205978.55 with a remainder of 0.365.
