Let's divide 690613 by 80
We want to figure out the number of times 690613 can be divided by 80.

Moving on to step 1:
6 divided by 80 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 80

On to step 2:
80 goes into 69 0 times with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 80

Moving on to step 3:
690 divided by 80 is 8 with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 50 after subtracting 640 from 690.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 80

Moving on to step 4:
The number 80 fits into 506 6 times, leaving a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Deduct 480 from 506 and we're left with 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 80

Going ahead to step 5:
80 can be fit into 261 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 863.0
Subtract 240 from 261 to get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 80

Moving on to step 6:
80 goes into 213 2 times with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 8632.0
If we subtract 160 from 213, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
The number 80 fits into 530 6 times, leaving a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 8632.6
Deduct 480 from 530 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 80 fits into 500 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 8632.66
If we subtract 480 from 500, 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.

In conclusion, the division gives 8632.66 with a balance of 0.02.
