80463458 divided by 546 
We want to figure out the number of times 80463458 can be divided by 546.

Step 1:
546 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 546

Moving on to step 2:
When dividing 80 by 546, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 546

Let's proceed to step 3:
When dividing 804 by 546, we get 1 with a remainder of 258.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 546 from 804 and we're left with 258.
Fetch the next digit (6) from the dividend, attach it to 258 and continue: 2586 / 546

Step 4:
546 can be fit into 2586 4 times, resulting in a remainder of 402.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 2184 from 2586 leaves us with 402.
Grab the next digit (3) from the dividend, add it to 402, then carry on: 4023 / 546

Moving on to step 5:
The number 546 fits into 4023 7 times, leaving a remainder of 201.
The next digit of our result is 7. 
Result so far: 147.0
Deduct 3822 from 4023 and we're left with 201.
Fetch the next digit (4) from the dividend, attach it to 201 and continue: 2014 / 546

Let's proceed to step 6:
When dividing 2014 by 546, we get 3 with a remainder of 376.
The next digit of our result is 3. 
Result so far: 1473.0
Subtract 1638 from 2014 to get 376.
Take the next digit (5) from the dividend and append it to 376, then repeat: 3765 / 546

On to step 7:
546 can be fit into 3765 6 times, resulting in a remainder of 489.
Put 6 as the next digit of the answer. 
Result so far: 14736.0
If we subtract 3276 from 3765, we get 489.
Append the next digit (8) from the dividend to 489 and continue with: 4898 / 546

Advancing to step 8:
If we divide 4898 by 546, we get 8 and a remainder of 530.
The next digit of our result is 8. 
Result so far: 147368.0
The remainder is 530 after subtracting 4368 from 4898.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 9:
The number 546 fits into 5300 9 times, leaving a remainder of 386.
Record the quotient 9 as the next digit in the result. 
Result so far: 147368.9
If we subtract 4914 from 5300, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 10:
The number 546 fits into 3860 7 times, leaving a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 147368.97
Subtracting 3822 from 3860 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
546 can be fit into 380 0 times, resulting in a remainder of 380.
The next digit of our result is 0. 
Result so far: 147368.97
If we take 0 away from 380, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 12:
If we divide 3800 by 546, we get 6 and a remainder of 524.
Put 6 as the next digit of the answer. 
Result so far: 147368.9706
If we take 3276 away from 3800, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 13:
The number 546 fits into 5240 9 times, leaving a remainder of 326.
The number 9 becomes the next digit in our result. 
Result so far: 147368.97069
Subtract 4914 from 5240 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 14:
3260 divided by 546 is 5 with a remainder of 530.
Put 5 as the next digit of the answer. 
Result so far: 147368.970695
Subtracting 2730 from 3260 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 15:
When dividing 5300 by 546, we get 9 with a remainder of 386.
Record the quotient 9 as the next digit in the result. 
Result so far: 147368.9706959
If we subtract 4914 from 5300, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 16:
546 can be fit into 3860 7 times, resulting in a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 147368.97069597
If we take 3822 away from 3860, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 147368.97069597 and a remainder of 3.8e-08.
