We look at the division of 87842643 by 854 
We want to figure out the number of times 87842643 can be divided by 854.

Step 1:
854 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 854

Let's proceed to step 2:
If we divide 87 by 854, we get 0 and a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Grab the next digit (8) from the dividend, add it to 87, then carry on: 878 / 854

Advancing to step 3:
854 goes into 878 1 times with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 24 after subtracting 854 from 878.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 854

Moving on to step 4:
244 divided by 854 is 0 with a remainder of 244.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 244, we end up with 244.
Append the next digit (2) from the dividend to 244 and continue with: 2442 / 854

On to step 5:
If we divide 2442 by 854, we get 2 and a remainder of 734.
The next digit of our result is 2. 
Result so far: 102.0
The remainder is 734 after subtracting 1708 from 2442.
Take the next digit (6) from the dividend and append it to 734, then repeat: 7346 / 854

Moving on to step 6:
The number 854 fits into 7346 8 times, leaving a remainder of 514.
Record the quotient 8 as the next digit in the result. 
Result so far: 1028.0
If we take 6832 away from 7346, we end up with 514.
Grab the next digit (4) from the dividend, add it to 514, then carry on: 5144 / 854

Step 7:
5144 divided by 854 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 10286.0
Subtracting 5124 from 5144 leaves us with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 854

Let's proceed to step 8:
If we divide 203 by 854, we get 0 and a remainder of 203.
The number 0 becomes the next digit in our result. 
Result so far: 102860.0
If we subtract 0 from 203, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 9:
The number 854 fits into 2030 2 times, leaving a remainder of 322.
Write down 2 as next digit of the result. 
Result so far: 102860.2
The remainder is 322 after subtracting 1708 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 10:
The number 854 fits into 3220 3 times, leaving a remainder of 658.
The next digit of our result is 3. 
Result so far: 102860.23
If we take 2562 away from 3220, we end up with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Advancing to step 11:
The number 854 fits into 6580 7 times, leaving a remainder of 602.
Put 7 as the next digit of the answer. 
Result so far: 102860.237
The remainder is 602 after subtracting 5978 from 6580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Advancing to step 12:
854 can be fit into 6020 7 times, resulting in a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 102860.2377
Subtract 5978 from 6020 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 102860.2377 with a remaining 0.00042.
