We're dividing 54656287 by 398 
We want to figure out the number of times 54656287 can be divided by 398.

Going ahead to step 1:
398 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 398

Let's proceed to step 2:
When dividing 54 by 398, we get 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 398

Moving on to step 3:
398 goes into 546 1 times with a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 398 from 546 and we're left with 148.
Append the next digit (5) from the dividend to 148 and continue with: 1485 / 398

Step 4:
1485 divided by 398 is 3 with a remainder of 291.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1194 from 1485 to get 291.
Fetch the next digit (6) from the dividend, attach it to 291 and continue: 2916 / 398

Moving on to step 5:
2916 divided by 398 is 7 with a remainder of 130.
Use 7 as the next digit of our solution. 
Result so far: 137.0
If we take 2786 away from 2916, we end up with 130.
Include the next digit (2) from the dividend after 130, then repeat: 1302 / 398

Moving on to step 6:
398 can be fit into 1302 3 times, resulting in a remainder of 108.
The next digit of our result is 3. 
Result so far: 1373.0
Deduct 1194 from 1302 and we're left with 108.
Grab the next digit (8) from the dividend, add it to 108, then carry on: 1088 / 398

Step 7:
398 goes into 1088 2 times with a remainder of 292.
Put 2 as the next digit of the answer. 
Result so far: 13732.0
If we take 796 away from 1088, we end up with 292.
Fetch the next digit (7) from the dividend, attach it to 292 and continue: 2927 / 398

On to step 8:
398 can be fit into 2927 7 times, resulting in a remainder of 141.
Record the quotient 7 as the next digit in the result. 
Result so far: 137327.0
If we take 2786 away from 2927, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 9:
398 can be fit into 1410 3 times, resulting in a remainder of 216.
Write down 3 as next digit of the result. 
Result so far: 137327.3
Deduct 1194 from 1410 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 10:
398 goes into 2160 5 times with a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 137327.35
If we take 1990 away from 2160, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 11:
The number 398 fits into 1700 4 times, leaving a remainder of 108.
The next digit of our result is 4. 
Result so far: 137327.354
Subtract 1592 from 1700 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 12:
If we divide 1080 by 398, we get 2 and a remainder of 284.
The next digit of our result is 2. 
Result so far: 137327.3542
The remainder is 284 after subtracting 796 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 13:
When dividing 2840 by 398, we get 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 137327.35427
Subtract 2786 from 2840 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
398 can be fit into 540 1 times, resulting in a remainder of 142.
The number 1 becomes the next digit in our result. 
Result so far: 137327.354271
If we take 398 away from 540, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 15:
398 goes into 1420 3 times with a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 137327.3542713
If we take 1194 away from 1420, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 16:
The number 398 fits into 2260 5 times, leaving a remainder of 270.
Use 5 as the next digit of our solution. 
Result so far: 137327.35427135
The remainder is 270 after subtracting 1990 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final outcome is 137327.35427135, with a leftover of 2.7e-07.
