We're dividing 854453 by 87 
Let's see how many times 87 fits into 854453.

On to step 1:
If we divide 8 by 87, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 87

Step 2:
87 can be fit into 85 0 times, resulting in a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Bring next digit (4) of the dividend behind the 85 and repeat the process: 854 / 87

Going ahead to step 3:
854 divided by 87 is 9 with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 783 from 854 leaves us with 71.
Append the next digit (4) from the dividend to 71 and continue with: 714 / 87

Let's proceed to step 4:
714 divided by 87 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Deduct 696 from 714 and we're left with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 87

Step 5:
When dividing 185 by 87, we get 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 982.0
Subtracting 174 from 185 leaves us with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 87

Advancing to step 6:
The number 87 fits into 113 1 times, leaving a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 9821.0
Subtracting 87 from 113 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
260 divided by 87 is 2 with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 9821.2
If we take 174 away from 260, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 8:
87 can be fit into 860 9 times, resulting in a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 9821.29
If we subtract 783 from 860, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 9:
87 can be fit into 770 8 times, resulting in a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 9821.298
If we take 696 away from 770, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
740 divided by 87 is 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 9821.2988
If we subtract 696 from 740, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 9821.2988, with a leftover of 0.00044.
