243552 ÷ 77 
We want to divide 243552 by 77.

Let's proceed to step 1:
The number 77 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 77

Let's proceed to step 2:
When dividing 24 by 77, we get 0 with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 77

Going ahead to step 3:
243 divided by 77 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 231 from 243 and we're left with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 77

Advancing to step 4:
When dividing 125 by 77, we get 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 77 from 125 leaves us with 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 77

Moving on to step 5:
485 divided by 77 is 6 with a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 316.0
If we subtract 462 from 485, we get 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 77

Let's proceed to step 6:
If we divide 232 by 77, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3163.0
Subtract 231 from 232 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
77 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3163.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
77 goes into 100 1 times with a remainder of 23.
The next digit of our result is 1. 
Result so far: 3163.01
The remainder is 23 after subtracting 77 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
The number 77 fits into 230 2 times, leaving a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 3163.012
If we subtract 154 from 230, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
77 can be fit into 760 9 times, resulting in a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 3163.0129
Subtract 693 from 760 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
If we divide 670 by 77, we get 8 and a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 3163.01298
Deduct 616 from 670 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
77 can be fit into 540 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 3163.012987
If we take 539 away from 540, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
If we divide 10 by 77, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3163.012987
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
If we divide 100 by 77, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 3163.01298701
Deduct 77 from 100 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 3163.01298701, with a leftover of 2.3e-08.
