679290 ÷ 90 
Let's see how many times 90 fits into 679290.

Advancing to step 1:
90 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 90

Moving on to step 2:
When dividing 67 by 90, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 90

Let's proceed to step 3:
90 goes into 679 7 times with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 630 from 679, we get 49.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 90

On to step 4:
492 divided by 90 is 5 with a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we subtract 450 from 492, we get 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 90

Step 5:
429 divided by 90 is 4 with a remainder of 69.
Record the quotient 4 as the next digit in the result. 
Result so far: 754.0
Subtract 360 from 429 to get 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 90

Moving on to step 6:
If we divide 690 by 90, we get 7 and a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 7547.0
The remainder is 60 after subtracting 630 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
If we divide 600 by 90, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 7547.6
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 7547.66
The remainder is 60 after subtracting 540 from 600.
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 7547.66 with a balance of 0.06.
