255284 divided by 902 
We're looking to find how many times 902 goes into 255284.

Step 1:
902 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 902

Advancing to step 2:
25 divided by 902 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 902

Advancing to step 3:
The number 902 fits into 255 0 times, leaving a remainder of 255.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 255 after subtracting 0 from 255.
Include the next digit (2) from the dividend after 255, then repeat: 2552 / 902

Let's proceed to step 4:
902 can be fit into 2552 2 times, resulting in a remainder of 748.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1804 from 2552 to get 748.
Fetch the next digit (8) from the dividend, attach it to 748 and continue: 7488 / 902

Step 5:
902 goes into 7488 8 times with a remainder of 272.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 7216 from 7488 leaves us with 272.
Append the next digit (4) from the dividend to 272 and continue with: 2724 / 902

Step 6:
When dividing 2724 by 902, we get 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 283.0
If we take 2706 away from 2724, 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 7:
902 goes into 180 0 times with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 283.0
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 8:
1800 divided by 902 is 1 with a remainder of 898.
The next digit of our result is 1. 
Result so far: 283.01
Deduct 902 from 1800 and we're left with 898.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8980, and continue the process.

Moving on to step 9:
When dividing 8980 by 902, we get 9 with a remainder of 862.
Record the quotient 9 as the next digit in the result. 
Result so far: 283.019
Deduct 8118 from 8980 and we're left with 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

Moving on to step 10:
8620 divided by 902 is 9 with a remainder of 502.
The next digit of our result is 9. 
Result so far: 283.0199
Deduct 8118 from 8620 and we're left with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

The final outcome is 283.0199, with a leftover of 0.00502.
