8574308 ÷ 902 
Let's see how many times 902 fits into 8574308.

Step 1:
If we divide 8 by 902, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 902

Advancing to step 2:
The number 902 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Include the next digit (7) from the dividend after 85, then repeat: 857 / 902

Going ahead to step 3:
The number 902 fits into 857 0 times, leaving a remainder of 857.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 857 to get 857.
Grab the next digit (4) from the dividend, add it to 857, then carry on: 8574 / 902

Moving on to step 4:
902 can be fit into 8574 9 times, resulting in a remainder of 456.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 456 after subtracting 8118 from 8574.
Fetch the next digit (3) from the dividend, attach it to 456 and continue: 4563 / 902

Moving on to step 5:
902 goes into 4563 5 times with a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Deduct 4510 from 4563 and we're left with 53.
Append the next digit (0) from the dividend to 53 and continue with: 530 / 902

On to step 6:
When dividing 530 by 902, we get 0 with a remainder of 530.
The next digit of our result is 0. 
Result so far: 950.0
Subtracting 0 from 530 leaves us with 530.
Take the next digit (8) from the dividend and append it to 530, then repeat: 5308 / 902

Step 7:
When dividing 5308 by 902, we get 5 with a remainder of 798.
The next digit of our result is 5. 
Result so far: 9505.0
The remainder is 798 after subtracting 4510 from 5308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

On to step 8:
The number 902 fits into 7980 8 times, leaving a remainder of 764.
Write down 8 as next digit of the result. 
Result so far: 9505.8
Subtract 7216 from 7980 to get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

On to step 9:
When dividing 7640 by 902, we get 8 with a remainder of 424.
The next digit of our result is 8. 
Result so far: 9505.88
Subtract 7216 from 7640 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

The quotient of the division is 9505.88, and the remainder is 0.424.
