Let's divide 243390 by 77
Let's see how many times 77 fits into 243390.

On to step 1:
2 divided by 77 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 77

Moving on to step 2:
If we divide 24 by 77, we get 0 and a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 77

Moving on to step 3:
When dividing 243 by 77, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 231 from 243 and we're left with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 77

Step 4:
If we divide 123 by 77, we get 1 and a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 46 after subtracting 77 from 123.
Append the next digit (9) from the dividend to 46 and continue with: 469 / 77

Let's proceed to step 5:
77 goes into 469 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 316.0
Subtracting 462 from 469 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 77

Let's proceed to step 6:
If we divide 70 by 77, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 3160.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 7:
700 divided by 77 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 3160.9
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
70 divided by 77 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 3160.9
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
If we divide 700 by 77, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 3160.909
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
The number 77 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 3160.909
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
77 goes into 700 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 3160.90909
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
77 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 3160.90909
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
When dividing 700 by 77, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 3160.9090909
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
If we divide 70 by 77, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 3160.9090909
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 3160.9090909 with a remainder of 7e-08.
