7 divided by 546 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 546

Let's proceed to step 2:
If we divide 70 by 546, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Append the next digit (0) from the dividend to 70 and continue with: 700 / 546

On to step 3:
The number 546 fits into 700 1 times, leaving a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 154 after subtracting 546 from 700.
Bring next digit (3) of the dividend behind the 154 and repeat the process: 1543 / 546

Moving on to step 4:
The number 546 fits into 1543 2 times, leaving a remainder of 451.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1092 from 1543, we get 451.
Take the next digit (0) from the dividend and append it to 451, then repeat: 4510 / 546

Let's proceed to step 5:
546 can be fit into 4510 8 times, resulting in a remainder of 142.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Deduct 4368 from 4510 and we're left with 142.
Take the next digit (3) from the dividend and append it to 142, then repeat: 1423 / 546

Let's proceed to step 6:
546 can be fit into 1423 2 times, resulting in a remainder of 331.
The number 2 becomes the next digit in our result. 
Result so far: 1282.0
Subtracting 1092 from 1423 leaves us with 331.
Grab the next digit (9) from the dividend, add it to 331, then carry on: 3319 / 546

Step 7:
3319 divided by 546 is 6 with a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 12826.0
Subtracting 3276 from 3319 leaves us with 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 546

Advancing to step 8:
When dividing 431 by 546, we get 0 with a remainder of 431.
The next digit of our result is 0. 
Result so far: 128260.0
Subtract 0 from 431 to get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Step 9:
4310 divided by 546 is 7 with a remainder of 488.
The number 7 becomes the next digit in our result. 
Result so far: 128260.7
Deduct 3822 from 4310 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 10:
If we divide 4880 by 546, we get 8 and a remainder of 512.
Record the quotient 8 as the next digit in the result. 
Result so far: 128260.78
Deduct 4368 from 4880 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 11:
5120 divided by 546 is 9 with a remainder of 206.
Put 9 as the next digit of the answer. 
Result so far: 128260.789
If we take 4914 away from 5120, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 12:
546 can be fit into 2060 3 times, resulting in a remainder of 422.
Use 3 as the next digit of our solution. 
Result so far: 128260.7893
Deduct 1638 from 2060 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 13:
If we divide 4220 by 546, we get 7 and a remainder of 398.
Put 7 as the next digit of the answer. 
Result so far: 128260.78937
Deduct 3822 from 4220 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 14:
546 goes into 3980 7 times with a remainder of 158.
Put 7 as the next digit of the answer. 
Result so far: 128260.789377
The remainder is 158 after subtracting 3822 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Our division results in 128260.789377 with a remaining 1.58e-05.
