693610 ÷ 80 
We want to figure out the number of times 693610 can be divided by 80.

On to step 1:
80 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
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:
The number 80 fits into 69 0 times, leaving a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 80

On to step 3:
693 divided by 80 is 8 with a remainder of 53.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 53 after subtracting 640 from 693.
Bring next digit (6) of the dividend behind the 53 and repeat the process: 536 / 80

Let's proceed to step 4:
The number 80 fits into 536 6 times, leaving a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtract 480 from 536 to get 56.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 80

Let's proceed to step 5:
80 can be fit into 561 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 867.0
If we take 560 away from 561, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 80

Moving on to step 6:
If we divide 10 by 80, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 8670.0
Subtracting 0 from 10 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.

Moving on to step 7:
If we divide 100 by 80, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 8670.1
If we take 80 away from 100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 8670.12
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 8670.125
If we take 400 away from 400, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8670.125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8670.125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 8670.125 with a remainder of 0.0.
