55316074 ÷ 398 
Our goal is to divide 55316074 by 398.

Step 1:
If we divide 5 by 398, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 398

Step 2:
398 can be fit into 55 0 times, resulting in a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Grab the next digit (3) from the dividend, add it to 55, then carry on: 553 / 398

Step 3:
If we divide 553 by 398, we get 1 and a remainder of 155.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 398 from 553, we get 155.
Append the next digit (1) from the dividend to 155 and continue with: 1551 / 398

Moving on to step 4:
If we divide 1551 by 398, we get 3 and a remainder of 357.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1194 from 1551 leaves us with 357.
Fetch the next digit (6) from the dividend, attach it to 357 and continue: 3576 / 398

Moving on to step 5:
If we divide 3576 by 398, we get 8 and a remainder of 392.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
The remainder is 392 after subtracting 3184 from 3576.
Append the next digit (0) from the dividend to 392 and continue with: 3920 / 398

Going ahead to step 6:
If we divide 3920 by 398, we get 9 and a remainder of 338.
Write down 9 as next digit of the result. 
Result so far: 1389.0
The remainder is 338 after subtracting 3582 from 3920.
Append the next digit (7) from the dividend to 338 and continue with: 3387 / 398

Let's proceed to step 7:
398 goes into 3387 8 times with a remainder of 203.
Put 8 as the next digit of the answer. 
Result so far: 13898.0
Subtracting 3184 from 3387 leaves us with 203.
Bring next digit (4) of the dividend behind the 203 and repeat the process: 2034 / 398

On to step 8:
398 goes into 2034 5 times with a remainder of 44.
Write down 5 as next digit of the result. 
Result so far: 138985.0
The remainder is 44 after subtracting 1990 from 2034.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
If we divide 440 by 398, we get 1 and a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 138985.1
Subtracting 398 from 440 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
If we divide 420 by 398, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 138985.11
The remainder is 22 after subtracting 398 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 138985.11 with a balance of 0.022.
