709945 divided by 90 
Our goal is to divide 709945 by 90.

Going ahead to step 1:
If we divide 7 by 90, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 90

On to step 2:
The number 90 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 90

Moving on to step 3:
When dividing 709 by 90, we get 7 with a remainder of 79.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 630 from 709 to get 79.
Bring next digit (9) of the dividend behind the 79 and repeat the process: 799 / 90

Advancing to step 4:
The number 90 fits into 799 8 times, leaving a remainder of 79.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtracting 720 from 799 leaves us with 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 90

On to step 5:
The number 90 fits into 794 8 times, leaving a remainder of 74.
The next digit of our result is 8. 
Result so far: 788.0
Subtracting 720 from 794 leaves us with 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 90

Let's proceed to step 6:
When dividing 745 by 90, we get 8 with a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 7888.0
The remainder is 25 after subtracting 720 from 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
90 goes into 250 2 times with a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 7888.2
If we subtract 180 from 250, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
700 divided by 90 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 7888.27
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 7888.277
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 7888.277, with a leftover of 0.007.
