We divide 258369 by 77
Our goal is to divide 258369 by 77.

Step 1:
The number 77 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 77

On to step 2:
If we divide 25 by 77, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 77

Advancing to step 3:
77 can be fit into 258 3 times, resulting in a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 231 away from 258, we end up with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 77

Step 4:
If we divide 273 by 77, we get 3 and a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 231 away from 273, we end up with 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 77

Going ahead to step 5:
The number 77 fits into 426 5 times, leaving a remainder of 41.
The next digit of our result is 5. 
Result so far: 335.0
If we subtract 385 from 426, we get 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 77

On to step 6:
419 divided by 77 is 5 with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 3355.0
The remainder is 34 after subtracting 385 from 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
77 goes into 340 4 times with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 3355.4
The remainder is 32 after subtracting 308 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
The number 77 fits into 320 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 3355.44
Subtracting 308 from 320 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 3355.44, and the remainder is 0.012.
