We're dividing 78513581 by 546 
We're looking to find how many times 546 goes into 78513581.

Going ahead to step 1:
546 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 546

Moving on to step 2:
When dividing 78 by 546, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 546

On to step 3:
The number 546 fits into 785 1 times, leaving a remainder of 239.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 546 from 785 to get 239.
Bring next digit (1) of the dividend behind the 239 and repeat the process: 2391 / 546

Step 4:
2391 divided by 546 is 4 with a remainder of 207.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 2184 from 2391 to get 207.
Include the next digit (3) from the dividend after 207, then repeat: 2073 / 546

Step 5:
546 can be fit into 2073 3 times, resulting in a remainder of 435.
Write down 3 as next digit of the result. 
Result so far: 143.0
If we take 1638 away from 2073, we end up with 435.
Grab the next digit (5) from the dividend, add it to 435, then carry on: 4355 / 546

Going ahead to step 6:
546 goes into 4355 7 times with a remainder of 533.
The number 7 becomes the next digit in our result. 
Result so far: 1437.0
If we take 3822 away from 4355, we end up with 533.
Include the next digit (8) from the dividend after 533, then repeat: 5338 / 546

Moving on to step 7:
546 can be fit into 5338 9 times, resulting in a remainder of 424.
The next digit of our result is 9. 
Result so far: 14379.0
The remainder is 424 after subtracting 4914 from 5338.
Bring next digit (1) of the dividend behind the 424 and repeat the process: 4241 / 546

Advancing to step 8:
When dividing 4241 by 546, we get 7 with a remainder of 419.
The next digit of our result is 7. 
Result so far: 143797.0
Subtract 3822 from 4241 to get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Moving on to step 9:
The number 546 fits into 4190 7 times, leaving a remainder of 368.
Use 7 as the next digit of our solution. 
Result so far: 143797.7
The remainder is 368 after subtracting 3822 from 4190.
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 10:
If we divide 3680 by 546, we get 6 and a remainder of 404.
Write down 6 as next digit of the result. 
Result so far: 143797.76
If we take 3276 away from 3680, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 11:
If we divide 4040 by 546, we get 7 and a remainder of 218.
Record the quotient 7 as the next digit in the result. 
Result so far: 143797.767
Subtracting 3822 from 4040 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 12:
When dividing 2180 by 546, we get 3 with a remainder of 542.
Put 3 as the next digit of the answer. 
Result so far: 143797.7673
If we take 1638 away from 2180, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

On to step 13:
5420 divided by 546 is 9 with a remainder of 506.
Record the quotient 9 as the next digit in the result. 
Result so far: 143797.76739
Subtract 4914 from 5420 to get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Going ahead to step 14:
5060 divided by 546 is 9 with a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 143797.767399
Subtracting 4914 from 5060 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final result is 143797.767399 with a remainder of 1.46e-05.
