We're dividing 512457 by 91 
Let's see how many times 91 fits into 512457.

Going ahead to step 1:
The number 91 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 91

On to step 2:
91 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 91

Moving on to step 3:
91 goes into 512 5 times with a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 455 from 512 leaves us with 57.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 91

Let's proceed to step 4:
91 goes into 574 6 times with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 56.0
The remainder is 28 after subtracting 546 from 574.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 91

Step 5:
If we divide 285 by 91, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 563.0
If we take 273 away from 285, we end up with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 91

On to step 6:
The number 91 fits into 127 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 5631.0
The remainder is 36 after subtracting 91 from 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
When dividing 360 by 91, we get 3 with a remainder of 87.
The next digit of our result is 3. 
Result so far: 5631.3
If we subtract 273 from 360, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 8:
91 can be fit into 870 9 times, resulting in a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 5631.39
Subtracting 819 from 870 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
If we divide 510 by 91, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 5631.395
Subtract 455 from 510 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
91 goes into 550 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 5631.3956
Subtract 546 from 550 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
When dividing 40 by 91, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 5631.3956
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
When dividing 400 by 91, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 5631.395604
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
When dividing 360 by 91, we get 3 with a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 5631.3956043
Subtract 273 from 360 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 14:
870 divided by 91 is 9 with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 5631.39560439
If we subtract 819 from 870, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The quotient of the division is 5631.39560439, and the remainder is 5.1e-08.
