We're dividing 70389 by 89 
Let's see how many times 89 fits into 70389.

Advancing to step 1:
89 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 89

Moving on to step 2:
The number 89 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 89

Going ahead to step 3:
89 can be fit into 703 7 times, resulting in a remainder of 80.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 623 from 703 leaves us with 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 89

Moving on to step 4:
808 divided by 89 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtract 801 from 808 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 89

Going ahead to step 5:
When dividing 79 by 89, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 790.0
If we subtract 0 from 79, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 6:
When dividing 790 by 89, we get 8 with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 790.8
Subtract 712 from 790 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 7:
89 can be fit into 780 8 times, resulting in a remainder of 68.
The next digit of our result is 8. 
Result so far: 790.88
Deduct 712 from 780 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 790.88, and the remainder is 0.068.
