54819896 divided by 398 
Our goal is to divide 54819896 by 398.

Let's proceed to step 1:
If we divide 5 by 398, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 398

On to step 2:
If we divide 54 by 398, we get 0 and a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 398

On to step 3:
548 divided by 398 is 1 with a remainder of 150.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 398 from 548, we get 150.
Take the next digit (1) from the dividend and append it to 150, then repeat: 1501 / 398

On to step 4:
398 goes into 1501 3 times with a remainder of 307.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 307 after subtracting 1194 from 1501.
Grab the next digit (9) from the dividend, add it to 307, then carry on: 3079 / 398

Going ahead to step 5:
3079 divided by 398 is 7 with a remainder of 293.
Write down 7 as next digit of the result. 
Result so far: 137.0
The remainder is 293 after subtracting 2786 from 3079.
Include the next digit (8) from the dividend after 293, then repeat: 2938 / 398

Advancing to step 6:
When dividing 2938 by 398, we get 7 with a remainder of 152.
The number 7 becomes the next digit in our result. 
Result so far: 1377.0
Subtracting 2786 from 2938 leaves us with 152.
Bring next digit (9) of the dividend behind the 152 and repeat the process: 1529 / 398

On to step 7:
1529 divided by 398 is 3 with a remainder of 335.
The next digit of our result is 3. 
Result so far: 13773.0
Subtract 1194 from 1529 to get 335.
Take the next digit (6) from the dividend and append it to 335, then repeat: 3356 / 398

On to step 8:
398 goes into 3356 8 times with a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 137738.0
If we subtract 3184 from 3356, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 9:
1720 divided by 398 is 4 with a remainder of 128.
The next digit of our result is 4. 
Result so far: 137738.4
Deduct 1592 from 1720 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 10:
If we divide 1280 by 398, we get 3 and a remainder of 86.
Put 3 as the next digit of the answer. 
Result so far: 137738.43
If we subtract 1194 from 1280, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 11:
860 divided by 398 is 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 137738.432
Subtract 796 from 860 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
640 divided by 398 is 1 with a remainder of 242.
Put 1 as the next digit of the answer. 
Result so far: 137738.4321
Subtracting 398 from 640 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 13:
398 can be fit into 2420 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 137738.43216
Deduct 2388 from 2420 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
398 can be fit into 320 0 times, resulting in a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 137738.43216
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 15:
398 goes into 3200 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 137738.4321608
Subtracting 3184 from 3200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 16:
If we divide 160 by 398, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 137738.4321608
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 137738.4321608 with a balance of 1.6e-07.
