Let's divide 646197 by 80
We want to figure out the number of times 646197 can be divided by 80.

On to step 1:
The number 80 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 80

Step 2:
The number 80 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 80

Moving on to step 3:
If we divide 646 by 80, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 640 from 646 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 80

On to step 4:
80 goes into 61 0 times with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtracting 0 from 61 leaves us with 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 80

On to step 5:
If we divide 619 by 80, we get 7 and a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 807.0
If we take 560 away from 619, we end up with 59.
Bring next digit (7) of the dividend behind the 59 and repeat the process: 597 / 80

On to step 6:
When dividing 597 by 80, we get 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 8077.0
Subtract 560 from 597 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
The number 80 fits into 370 4 times, leaving a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 8077.4
Deduct 320 from 370 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.
The number 6 becomes the next digit in our result. 
Result so far: 8077.46
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.

Going ahead to step 9:
80 goes into 200 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 8077.462
If we take 160 away from 200, we end up 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.

Moving on to step 10:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8077.4625
If we subtract 400 from 400, we 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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8077.4625
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.

On to step 12:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8077.4625
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.

In conclusion, the division gives 8077.4625 with a balance of 0.0.
