We're dividing 679420 by 90 
We want to figure out the number of times 679420 can be divided by 90.

Going ahead to step 1:
6 divided by 90 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 90

Advancing to step 2:
The number 90 fits into 67 0 times, leaving a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 90

Going ahead to step 3:
When dividing 679 by 90, we get 7 with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 630 from 679 leaves us with 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 90

Advancing to step 4:
494 divided by 90 is 5 with a remainder of 44.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we take 450 away from 494, we end up with 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 90

Advancing to step 5:
The number 90 fits into 442 4 times, leaving a remainder of 82.
The next digit of our result is 4. 
Result so far: 754.0
If we subtract 360 from 442, we get 82.
Grab the next digit (0) from the dividend, add it to 82, then carry on: 820 / 90

Advancing to step 6:
90 can be fit into 820 9 times, resulting in a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 7549.0
Subtract 810 from 820 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
If we divide 100 by 90, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 7549.1
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 7549.11
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 7549.11 with a balance of 0.01.
