We divide 77821359 by 258
We want to divide 77821359 by 258.

Going ahead to step 1:
The number 258 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 258

Moving on to step 2:
258 goes into 77 0 times with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 258

Let's proceed to step 3:
When dividing 778 by 258, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 774 from 778, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 258

Going ahead to step 4:
258 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 42, we get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 258

Going ahead to step 5:
When dividing 421 by 258, we get 1 with a remainder of 163.
Use 1 as the next digit of our solution. 
Result so far: 301.0
If we take 258 away from 421, we end up with 163.
Bring next digit (3) of the dividend behind the 163 and repeat the process: 1633 / 258

Step 6:
258 goes into 1633 6 times with a remainder of 85.
Put 6 as the next digit of the answer. 
Result so far: 3016.0
If we subtract 1548 from 1633, we get 85.
Append the next digit (5) from the dividend to 85 and continue with: 855 / 258

Going ahead to step 7:
258 can be fit into 855 3 times, resulting in a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 30163.0
The remainder is 81 after subtracting 774 from 855.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 258

Let's proceed to step 8:
258 goes into 819 3 times with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 301633.0
If we take 774 away from 819, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
The number 258 fits into 450 1 times, leaving a remainder of 192.
The number 1 becomes the next digit in our result. 
Result so far: 301633.1
Deduct 258 from 450 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 10:
258 goes into 1920 7 times with a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 301633.17
Subtract 1806 from 1920 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 11:
The number 258 fits into 1140 4 times, leaving a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 301633.174
If we take 1032 away from 1140, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 12:
258 can be fit into 1080 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 301633.1744
If we take 1032 away from 1080, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 301633.1744 with a remaining 0.00048.
