Let's divide 686306 by 90
We want to divide 686306 by 90.

Advancing to step 1:
If we divide 6 by 90, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 90

Let's proceed to step 2:
If we divide 68 by 90, we get 0 and a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 90

Step 3:
If we divide 686 by 90, we get 7 and a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 630 from 686 and we're left with 56.
Take the next digit (3) from the dividend and append it to 56, then repeat: 563 / 90

Step 4:
If we divide 563 by 90, we get 6 and a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
If we subtract 540 from 563, we get 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 90

Let's proceed to step 5:
90 can be fit into 230 2 times, resulting in a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 762.0
Deduct 180 from 230 and we're left with 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 90

On to step 6:
The number 90 fits into 506 5 times, leaving a remainder of 56.
The number 5 becomes the next digit in our result. 
Result so far: 7625.0
Subtracting 450 from 506 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
If we divide 560 by 90, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 7625.6
If we subtract 540 from 560, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 7625.62
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 90, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 7625.622
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 7625.622 with a balance of 0.002.
