122149 ÷ 80 
We want to divide 122149 by 80.

On to step 1:
The number 80 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 80

Moving on to step 2:
80 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 80

Advancing to step 3:
If we divide 122 by 80, we get 1 and a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 80 away from 122, we end up with 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 80

Advancing to step 4:
80 can be fit into 421 5 times, resulting in a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 400 from 421 to get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 80

Step 5:
80 can be fit into 214 2 times, resulting in a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
If we take 160 away from 214, we end up with 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 80

On to step 6:
The number 80 fits into 549 6 times, leaving a remainder of 69.
Write down 6 as next digit of the result. 
Result so far: 1526.0
The remainder is 69 after subtracting 480 from 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 7:
690 divided by 80 is 8 with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 1526.8
If we subtract 640 from 690, 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.

Advancing to step 8:
500 divided by 80 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 1526.86
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.

Going ahead to step 9:
200 divided by 80 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 1526.862
Deduct 160 from 200 and we're left 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.

Let's proceed to step 10:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1526.8625
If we take 400 away from 400, 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.

Let's proceed to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1526.8625
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.

On to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1526.8625
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.

Our division results in 1526.8625 with a remaining 0.0.
