We look at the division of 813902 by 47 
We're looking to find how many times 47 goes into 813902.

Moving on to step 1:
47 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 47

Going ahead to step 2:
47 can be fit into 81 1 times, resulting in a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 47 away from 81, we end up with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 47

Moving on to step 3:
47 goes into 343 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 14 after subtracting 329 from 343.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 47

Advancing to step 4:
The number 47 fits into 149 3 times, leaving a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 173.0
Subtracting 141 from 149 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 47

On to step 5:
47 can be fit into 80 1 times, resulting in a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1731.0
The remainder is 33 after subtracting 47 from 80.
Take the next digit (2) from the dividend and append it to 33, then repeat: 332 / 47

On to step 6:
The number 47 fits into 332 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 17317.0
If we subtract 329 from 332, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 47 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 17317.0
If we take 0 away from 30, we end up 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.

Let's proceed to step 8:
47 goes into 300 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 17317.06
If we take 282 away from 300, we end up 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.

On to step 9:
180 divided by 47 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 17317.063
Subtracting 141 from 180 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 10:
47 goes into 390 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 17317.0638
Deduct 376 from 390 and we're left 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.

Step 11:
140 divided by 47 is 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 17317.06382
Subtract 94 from 140 to 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.

Let's proceed to step 12:
If we divide 460 by 47, we get 9 and a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 17317.063829
If we subtract 423 from 460, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 13:
When dividing 370 by 47, we get 7 with a remainder of 41.
The next digit of our result is 7. 
Result so far: 17317.0638297
Subtracting 329 from 370 leaves us with 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 14:
When dividing 410 by 47, we get 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 17317.06382978
The remainder is 34 after subtracting 376 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 17317.06382978 with a remainder of 3.4e-08.
