Let's divide 691997 by 80
Let's see how many times 80 fits into 691997.

On to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 80

Advancing to step 2:
When dividing 69 by 80, we get 0 with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 80

Advancing to step 3:
If we divide 691 by 80, we get 8 and a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 640 from 691 and we're left with 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 80

Advancing to step 4:
80 can be fit into 519 6 times, resulting in a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Subtract 480 from 519 to get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 80

Moving on to step 5:
80 can be fit into 399 4 times, resulting in a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 864.0
If we take 320 away from 399, we end up with 79.
Include the next digit (7) from the dividend after 79, then repeat: 797 / 80

On to step 6:
80 goes into 797 9 times with a remainder of 77.
The next digit of our result is 9. 
Result so far: 8649.0
Subtracting 720 from 797 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
80 can be fit into 770 9 times, resulting in a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 8649.9
Deduct 720 from 770 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.

Let's proceed to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 8649.96
If we take 480 away from 500, 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.

Moving on to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 8649.962
Subtracting 160 from 200 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
400 divided by 80 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 8649.9625
Deduct 400 from 400 and we're left 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.

On to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8649.9625
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.

Going ahead to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 8649.9625
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.

Our division results in 8649.9625 with a remaining 0.0.
