12279 ÷ 69 
Our goal is to divide 12279 by 69.

Step 1:
When dividing 1 by 69, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 69

Step 2:
69 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 69

Moving on to step 3:
69 can be fit into 122 1 times, resulting in a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 69 away from 122, we end up with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 69

Advancing to step 4:
The number 69 fits into 537 7 times, leaving a remainder of 54.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 483 from 537 leaves us with 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 69

Advancing to step 5:
69 goes into 549 7 times with a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 177.0
Subtract 483 from 549 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 6:
When dividing 660 by 69, we get 9 with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 177.9
If we subtract 621 from 660, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
When dividing 390 by 69, we get 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 177.95
Subtract 345 from 390 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
The number 69 fits into 450 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 177.956
If we take 414 away from 450, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
If we divide 360 by 69, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 177.9565
Subtract 345 from 360 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
150 divided by 69 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 177.95652
If we subtract 138 from 150, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
120 divided by 69 is 1 with a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 177.956521
Subtracting 69 from 120 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 12:
If we divide 510 by 69, we get 7 and a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 177.9565217
If we subtract 483 from 510, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 13:
If we divide 270 by 69, we get 3 and a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 177.95652173
If we subtract 207 from 270, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Our division results in 177.95652173 with a remaining 6.3e-08.
