Let's divide 789643 by 80
Let's see how many times 80 fits into 789643.

Advancing to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 80

On to step 2:
When dividing 78 by 80, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 80

Advancing to step 3:
80 can be fit into 789 9 times, resulting in a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 720 from 789, we get 69.
Bring next digit (6) of the dividend behind the 69 and repeat the process: 696 / 80

Advancing to step 4:
When dividing 696 by 80, we get 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtracting 640 from 696 leaves us with 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 80

Moving on to step 5:
80 can be fit into 564 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 987.0
Deduct 560 from 564 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 80

On to step 6:
80 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 9870.0
If we take 0 away from 43, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
When dividing 430 by 80, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 9870.5
If we take 400 away from 430, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 80 is 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 9870.53
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
80 goes into 600 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 9870.537
If we take 560 away from 600, 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.

On to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9870.5375
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.

Advancing to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9870.5375
Deduct 0 from 0 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.

Going ahead to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9870.5375
The remainder is 0 after subtracting 0 from 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 9870.5375 with a balance of 0.0.
