12391 divided by 47 
Let's see how many times 47 fits into 12391.

Let's proceed to step 1:
47 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 47

Moving on to step 2:
47 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 47

Moving on to step 3:
When dividing 123 by 47, we get 2 with a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 94 from 123 and we're left with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 47

Moving on to step 4:
299 divided by 47 is 6 with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtracting 282 from 299 leaves us with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 47

Advancing to step 5:
When dividing 171 by 47, we get 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 263.0
Subtracting 141 from 171 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 6:
47 goes into 300 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 263.6
Subtracting 282 from 300 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
47 goes into 180 3 times with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 263.63
The remainder is 39 after subtracting 141 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 8:
The number 47 fits into 390 8 times, leaving a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 263.638
Subtracting 376 from 390 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
140 divided by 47 is 2 with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 263.6382
If we subtract 94 from 140, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
The number 47 fits into 460 9 times, leaving a remainder of 37.
The next digit of our result is 9. 
Result so far: 263.63829
The remainder is 37 after subtracting 423 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 11:
The number 47 fits into 370 7 times, leaving a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 263.638297
Subtract 329 from 370 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 12:
47 goes into 410 8 times with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 263.6382978
If we take 376 away from 410, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
The number 47 fits into 340 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 263.63829787
If we take 329 away from 340, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 263.63829787 with a remaining 1.1e-08.
