546138 ÷ 91 
We want to figure out the number of times 546138 can be divided by 91.

Going ahead to step 1:
The number 91 fits into 5 0 times, leaving 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 / 91

Step 2:
54 divided by 91 is 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 91

Let's proceed to step 3:
546 divided by 91 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 546 from 546 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 91

Step 4:
If we divide 1 by 91, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 91

Advancing to step 5:
91 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 600.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 91

Let's proceed to step 6:
The number 91 fits into 138 1 times, leaving a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 6001.0
The remainder is 47 after subtracting 91 from 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
91 can be fit into 470 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 6001.5
Deduct 455 from 470 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
The number 91 fits into 150 1 times, leaving a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 6001.51
If we subtract 91 from 150, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
91 can be fit into 590 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 6001.516
Subtracting 546 from 590 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
91 can be fit into 440 4 times, resulting in a remainder of 76.
The next digit of our result is 4. 
Result so far: 6001.5164
If we subtract 364 from 440, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
The number 91 fits into 760 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 6001.51648
If we take 728 away from 760, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
91 goes into 320 3 times with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 6001.516483
Deduct 273 from 320 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
When dividing 470 by 91, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 6001.5164835
Subtract 455 from 470 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
The number 91 fits into 150 1 times, leaving a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 6001.51648351
Subtract 91 from 150 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 6001.51648351 with a remaining 5.9e-08.
