We look at the division of 863851 by 47 
We want to figure out the number of times 863851 can be divided by 47.

Going ahead to step 1:
47 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 47

Going ahead to step 2:
If we divide 86 by 47, we get 1 and a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 47 from 86 leaves us with 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 47

Going ahead to step 3:
When dividing 393 by 47, we get 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 376 away from 393, we end up with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 47

Advancing to step 4:
178 divided by 47 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 183.0
The remainder is 37 after subtracting 141 from 178.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 47

On to step 5:
47 goes into 375 7 times with a remainder of 46.
The next digit of our result is 7. 
Result so far: 1837.0
Deduct 329 from 375 and we're left with 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 47

Let's proceed to step 6:
When dividing 461 by 47, we get 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 18379.0
Subtract 423 from 461 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
If we divide 380 by 47, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 18379.8
If we subtract 376 from 380, we 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.

Let's proceed to step 8:
47 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 18379.8
The remainder is 40 after subtracting 0 from 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 9:
47 can be fit into 400 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 18379.808
Deduct 376 from 400 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
If we divide 240 by 47, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 18379.8085
If we subtract 235 from 240, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
If we divide 50 by 47, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 18379.80851
If we take 47 away from 50, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
The number 47 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 18379.80851
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
The number 47 fits into 300 6 times, leaving a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 18379.8085106
Deduct 282 from 300 and we're left 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.

Let's proceed to step 14:
47 goes into 180 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 18379.80851063
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.

The final outcome is 18379.80851063, with a leftover of 3.9e-08.
