961253 ÷ 80 
Let's see how many times 80 fits into 961253.

Advancing to step 1:
If we divide 9 by 80, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 80

Advancing to step 2:
80 goes into 96 1 times with a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
If we take 80 away from 96, we end up with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 80

Advancing to step 3:
161 divided by 80 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 160 from 161 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 80

Moving on to step 4:
The number 80 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 120.0
If we take 0 away from 12, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 80

Advancing to step 5:
80 goes into 125 1 times with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1201.0
Deduct 80 from 125 and we're left with 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 80

Step 6:
When dividing 453 by 80, we get 5 with a remainder of 53.
Write down 5 as next digit of the result. 
Result so far: 12015.0
The remainder is 53 after subtracting 400 from 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
80 goes into 530 6 times with a remainder of 50.
The next digit of our result is 6. 
Result so far: 12015.6
If we subtract 480 from 530, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
When dividing 500 by 80, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 12015.66
Subtract 480 from 500 to 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.

After the division, we end up with 12015.66 and a remainder of 0.02.
