181223 ÷ 77 
We're looking to find how many times 77 goes into 181223.

Step 1:
If we divide 1 by 77, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 77

Step 2:
The number 77 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 77

On to step 3:
When dividing 181 by 77, we get 2 with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 154 from 181 to get 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 77

Advancing to step 4:
77 can be fit into 272 3 times, resulting in a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 231 away from 272, we end up with 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 77

On to step 5:
412 divided by 77 is 5 with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 235.0
If we subtract 385 from 412, we get 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 77

Going ahead to step 6:
273 divided by 77 is 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 2353.0
If we take 231 away from 273, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
77 can be fit into 420 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2353.5
Subtracting 385 from 420 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
If we divide 350 by 77, we get 4 and a remainder of 42.
The next digit of our result is 4. 
Result so far: 2353.54
If we take 308 away from 350, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
77 can be fit into 420 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 2353.545
If we take 385 away from 420, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
350 divided by 77 is 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 2353.5454
If we subtract 308 from 350, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
The number 77 fits into 420 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 2353.54545
The remainder is 35 after subtracting 385 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
If we divide 350 by 77, we get 4 and a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 2353.545454
If we take 308 away from 350, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
77 can be fit into 420 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 2353.5454545
Subtract 385 from 420 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
77 goes into 350 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 2353.54545454
Deduct 308 from 350 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 2353.54545454 with a remaining 4.2e-08.
