91607 ÷ 80 
Our goal is to divide 91607 by 80.

Let's proceed to step 1:
80 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 80

Step 2:
91 divided by 80 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 11 after subtracting 80 from 91.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 80

Step 3:
When dividing 116 by 80, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 80 away from 116, we end up with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 80

Going ahead to step 4:
360 divided by 80 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
If we take 320 away from 360, we end up with 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 80

Moving on to step 5:
407 divided by 80 is 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 1145.0
If we take 400 away from 407, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 6:
When dividing 70 by 80, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1145.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 7:
If we divide 700 by 80, we get 8 and a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 1145.08
If we subtract 640 from 700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
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: 1145.087
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1145.0875
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.

Step 10:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1145.0875
If we subtract 0 from 0, 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.

Let's proceed to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1145.0875
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 1145.0875 with a balance of 0.0.
