We look at the division of 880390 by 93 
We're looking to find how many times 93 goes into 880390.

Step 1:
When dividing 8 by 93, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 93

Step 2:
When dividing 88 by 93, we get 0 with a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Take the next digit (0) from the dividend and append it to 88, then repeat: 880 / 93

On to step 3:
If we divide 880 by 93, we get 9 and a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 837 from 880 leaves us with 43.
Append the next digit (3) from the dividend to 43 and continue with: 433 / 93

Going ahead to step 4:
93 can be fit into 433 4 times, resulting in a remainder of 61.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Subtract 372 from 433 to get 61.
Append the next digit (9) from the dividend to 61 and continue with: 619 / 93

On to step 5:
If we divide 619 by 93, we get 6 and a remainder of 61.
The next digit of our result is 6. 
Result so far: 946.0
Subtract 558 from 619 to get 61.
Fetch the next digit (0) from the dividend, attach it to 61 and continue: 610 / 93

Advancing to step 6:
When dividing 610 by 93, we get 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 9466.0
Subtracting 558 from 610 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
93 can be fit into 520 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 9466.5
If we take 465 away from 520, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
93 goes into 550 5 times with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 9466.55
Deduct 465 from 550 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 9466.55 and a remainder of 0.085.
