Let's divide 998890 by 1
We want to divide 998890 by 1.

Advancing to step 1:
1 can be fit into 9 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 9 from 9 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Step 2:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we take 9 away from 9, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Moving on to step 3:
If we divide 8 by 1, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 998.0
Subtract 8 from 8 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

On to step 4:
8 divided by 1 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 9988.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Moving on to step 5:
1 goes into 9 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 99889.0
Subtracting 9 from 9 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

On to step 6:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 998890.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 998890.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 998890.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 998890.0 with a balance of 0.0.
