We're dividing 79638 by 90 
We want to divide 79638 by 90.

Let's proceed to step 1:
If we divide 7 by 90, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 90

Moving on to step 2:
79 divided by 90 is 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Grab the next digit (6) from the dividend, add it to 79, then carry on: 796 / 90

Moving on to step 3:
The number 90 fits into 796 8 times, leaving a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 720 from 796, we get 76.
Append the next digit (3) from the dividend to 76 and continue with: 763 / 90

Going ahead to step 4:
763 divided by 90 is 8 with a remainder of 43.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtracting 720 from 763 leaves us with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 90

Let's proceed to step 5:
When dividing 438 by 90, we get 4 with a remainder of 78.
The next digit of our result is 4. 
Result so far: 884.0
Deduct 360 from 438 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 6:
90 can be fit into 780 8 times, resulting in a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 884.8
The remainder is 60 after subtracting 720 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
If we divide 600 by 90, we get 6 and a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 884.86
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 884.866
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 884.866 with a balance of 0.006.
