We're dividing 98456476 by 287 
Our goal is to divide 98456476 by 287.

Advancing to step 1:
287 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 287

Moving on to step 2:
If we divide 98 by 287, we get 0 and a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Grab the next digit (4) from the dividend, add it to 98, then carry on: 984 / 287

On to step 3:
If we divide 984 by 287, we get 3 and a remainder of 123.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 861 from 984 and we're left with 123.
Include the next digit (5) from the dividend after 123, then repeat: 1235 / 287

Let's proceed to step 4:
If we divide 1235 by 287, we get 4 and a remainder of 87.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we take 1148 away from 1235, we end up with 87.
Bring next digit (6) of the dividend behind the 87 and repeat the process: 876 / 287

On to step 5:
287 goes into 876 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 343.0
If we subtract 861 from 876, we get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 287

Let's proceed to step 6:
When dividing 154 by 287, we get 0 with a remainder of 154.
The next digit of our result is 0. 
Result so far: 3430.0
Subtracting 0 from 154 leaves us with 154.
Append the next digit (7) from the dividend to 154 and continue with: 1547 / 287

Advancing to step 7:
287 goes into 1547 5 times with a remainder of 112.
The next digit of our result is 5. 
Result so far: 34305.0
Subtract 1435 from 1547 to get 112.
Take the next digit (6) from the dividend and append it to 112, then repeat: 1126 / 287

Going ahead to step 8:
287 can be fit into 1126 3 times, resulting in a remainder of 265.
Use 3 as the next digit of our solution. 
Result so far: 343053.0
The remainder is 265 after subtracting 861 from 1126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 9:
287 goes into 2650 9 times with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 343053.9
Subtract 2583 from 2650 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 10:
287 goes into 670 2 times with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 343053.92
If we subtract 574 from 670, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 11:
287 goes into 960 3 times with a remainder of 99.
The number 3 becomes the next digit in our result. 
Result so far: 343053.923
Subtract 861 from 960 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 12:
If we divide 990 by 287, we get 3 and a remainder of 129.
Record the quotient 3 as the next digit in the result. 
Result so far: 343053.9233
Deduct 861 from 990 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final outcome is 343053.9233, with a leftover of 0.00129.
