990458 ÷ 89 
Our goal is to divide 990458 by 89.

Going ahead to step 1:
The number 89 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 89

Going ahead to step 2:
89 goes into 99 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 89 away from 99, we end up with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 89

Moving on to step 3:
89 can be fit into 100 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 89 from 100 to get 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 89

Let's proceed to step 4:
89 goes into 114 1 times with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 111.0
Subtract 89 from 114 to get 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 89

Moving on to step 5:
If we divide 255 by 89, we get 2 and a remainder of 77.
Write down 2 as next digit of the result. 
Result so far: 1112.0
If we subtract 178 from 255, we get 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 89

Let's proceed to step 6:
778 divided by 89 is 8 with a remainder of 66.
The next digit of our result is 8. 
Result so far: 11128.0
Subtracting 712 from 778 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
89 goes into 660 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 11128.7
If we subtract 623 from 660, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
370 divided by 89 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 11128.74
Deduct 356 from 370 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
The number 89 fits into 140 1 times, leaving a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 11128.741
Subtracting 89 from 140 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 10:
510 divided by 89 is 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 11128.7415
If we subtract 445 from 510, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
89 can be fit into 650 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 11128.74157
If we take 623 away from 650, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 12:
270 divided by 89 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 11128.741573
Deduct 267 from 270 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
89 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 11128.741573
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
When dividing 300 by 89, we get 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 11128.74157303
Subtract 267 from 300 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

In conclusion, the division gives 11128.74157303 with a balance of 3.3e-08.
