We look at the division of 790138 by 89 
We want to figure out the number of times 790138 can be divided by 89.

Advancing to step 1:
The number 89 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 89

Moving on to step 2:
If we divide 79 by 89, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Take the next digit (0) from the dividend and append it to 79, then repeat: 790 / 89

Step 3:
89 can be fit into 790 8 times, resulting in a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 712 away from 790, we end up with 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 89

Advancing to step 4:
The number 89 fits into 781 8 times, leaving a remainder of 69.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Deduct 712 from 781 and we're left with 69.
Bring next digit (3) of the dividend behind the 69 and repeat the process: 693 / 89

Let's proceed to step 5:
If we divide 693 by 89, we get 7 and a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 887.0
Subtract 623 from 693 to get 70.
Include the next digit (8) from the dividend after 70, then repeat: 708 / 89

On to step 6:
708 divided by 89 is 7 with a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 8877.0
Deduct 623 from 708 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.

Let's proceed to step 7:
850 divided by 89 is 9 with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 8877.9
The remainder is 49 after subtracting 801 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 8:
89 goes into 490 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 8877.95
If we subtract 445 from 490, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
89 goes into 450 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8877.955
Deduct 445 from 450 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 8877.955 and a remainder of 0.0005.
