We divide 688390 by 84
We want to divide 688390 by 84.

On to step 1:
6 divided by 84 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
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 / 84

Let's proceed to step 2:
The number 84 fits into 68 0 times, leaving a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Append the next digit (8) from the dividend to 68 and continue with: 688 / 84

Moving on to step 3:
The number 84 fits into 688 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 672 from 688, we get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 84

Step 4:
163 divided by 84 is 1 with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 81.0
Deduct 84 from 163 and we're left with 79.
Bring next digit (9) of the dividend behind the 79 and repeat the process: 799 / 84

Let's proceed to step 5:
If we divide 799 by 84, we get 9 and a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 819.0
If we take 756 away from 799, we end up with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 84

Let's proceed to step 6:
When dividing 430 by 84, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 8195.0
If we take 420 away from 430, we end up 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.

Let's proceed to step 7:
If we divide 100 by 84, we get 1 and a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 8195.1
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
84 can be fit into 160 1 times, resulting in a remainder of 76.
The next digit of our result is 1. 
Result so far: 8195.11
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 8195.11 with a balance of 0.076.
