54216341 ÷ 498 
We want to figure out the number of times 54216341 can be divided by 498.

Step 1:
5 divided by 498 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 498

Advancing to step 2:
498 goes into 54 0 times with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 498

Advancing to step 3:
498 can be fit into 542 1 times, resulting in a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 498 from 542 and we're left with 44.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 498

Let's proceed to step 4:
When dividing 441 by 498, we get 0 with a remainder of 441.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 441, we get 441.
Bring next digit (6) of the dividend behind the 441 and repeat the process: 4416 / 498

On to step 5:
The number 498 fits into 4416 8 times, leaving a remainder of 432.
The next digit of our result is 8. 
Result so far: 108.0
Subtracting 3984 from 4416 leaves us with 432.
Fetch the next digit (3) from the dividend, attach it to 432 and continue: 4323 / 498

Moving on to step 6:
498 can be fit into 4323 8 times, resulting in a remainder of 339.
Write down 8 as next digit of the result. 
Result so far: 1088.0
Subtract 3984 from 4323 to get 339.
Fetch the next digit (4) from the dividend, attach it to 339 and continue: 3394 / 498

Going ahead to step 7:
When dividing 3394 by 498, we get 6 with a remainder of 406.
The next digit of our result is 6. 
Result so far: 10886.0
Deduct 2988 from 3394 and we're left with 406.
Append the next digit (1) from the dividend to 406 and continue with: 4061 / 498

Going ahead to step 8:
When dividing 4061 by 498, we get 8 with a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 108868.0
Subtract 3984 from 4061 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 9:
The number 498 fits into 770 1 times, leaving a remainder of 272.
Use 1 as the next digit of our solution. 
Result so far: 108868.1
Subtracting 498 from 770 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 10:
If we divide 2720 by 498, we get 5 and a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 108868.15
The remainder is 230 after subtracting 2490 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 11:
498 can be fit into 2300 4 times, resulting in a remainder of 308.
The number 4 becomes the next digit in our result. 
Result so far: 108868.154
If we subtract 1992 from 2300, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 12:
When dividing 3080 by 498, we get 6 with a remainder of 92.
The next digit of our result is 6. 
Result so far: 108868.1546
Deduct 2988 from 3080 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 13:
920 divided by 498 is 1 with a remainder of 422.
The next digit of our result is 1. 
Result so far: 108868.15461
Subtract 498 from 920 to get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 14:
If we divide 4220 by 498, we get 8 and a remainder of 236.
Record the quotient 8 as the next digit in the result. 
Result so far: 108868.154618
Subtract 3984 from 4220 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 15:
2360 divided by 498 is 4 with a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 108868.1546184
If we subtract 1992 from 2360, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 16:
The number 498 fits into 3680 7 times, leaving a remainder of 194.
The number 7 becomes the next digit in our result. 
Result so far: 108868.15461847
If we subtract 3486 from 3680, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The final outcome is 108868.15461847, with a leftover of 1.94e-07.
