Let's divide 54972855 by 397
We're looking to find how many times 397 goes into 54972855.

Moving on to step 1:
5 divided by 397 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 397

On to step 2:
54 divided by 397 is 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 397

Moving on to step 3:
When dividing 549 by 397, we get 1 with a remainder of 152.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 397 from 549 and we're left with 152.
Grab the next digit (7) from the dividend, add it to 152, then carry on: 1527 / 397

Step 4:
397 goes into 1527 3 times with a remainder of 336.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1191 from 1527 leaves us with 336.
Grab the next digit (2) from the dividend, add it to 336, then carry on: 3362 / 397

Going ahead to step 5:
The number 397 fits into 3362 8 times, leaving a remainder of 186.
Put 8 as the next digit of the answer. 
Result so far: 138.0
The remainder is 186 after subtracting 3176 from 3362.
Bring next digit (8) of the dividend behind the 186 and repeat the process: 1868 / 397

Moving on to step 6:
The number 397 fits into 1868 4 times, leaving a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 1384.0
Subtracting 1588 from 1868 leaves us with 280.
Include the next digit (5) from the dividend after 280, then repeat: 2805 / 397

Moving on to step 7:
If we divide 2805 by 397, we get 7 and a remainder of 26.
The next digit of our result is 7. 
Result so far: 13847.0
Subtracting 2779 from 2805 leaves us with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 397

Advancing to step 8:
If we divide 265 by 397, we get 0 and a remainder of 265.
Use 0 as the next digit of our solution. 
Result so far: 138470.0
Subtract 0 from 265 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 9:
397 can be fit into 2650 6 times, resulting in a remainder of 268.
The next digit of our result is 6. 
Result so far: 138470.6
If we subtract 2382 from 2650, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 10:
397 goes into 2680 6 times with a remainder of 298.
Put 6 as the next digit of the answer. 
Result so far: 138470.66
Subtracting 2382 from 2680 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

After the division, we end up with 138470.66 and a remainder of 0.298.
