77722450 ÷ 258 
Let's see how many times 258 fits into 77722450.

On to step 1:
If we divide 7 by 258, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 258

Going ahead to step 2:
If we divide 77 by 258, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 258

Advancing to step 3:
When dividing 777 by 258, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
If we take 774 away from 777, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 258

Going ahead to step 4:
32 divided by 258 is 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 32 after subtracting 0 from 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 258

Going ahead to step 5:
If we divide 322 by 258, we get 1 and a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 301.0
If we subtract 258 from 322, we get 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 258

Moving on to step 6:
When dividing 644 by 258, we get 2 with a remainder of 128.
The next digit of our result is 2. 
Result so far: 3012.0
If we take 516 away from 644, we end up with 128.
Include the next digit (5) from the dividend after 128, then repeat: 1285 / 258

Step 7:
The number 258 fits into 1285 4 times, leaving a remainder of 253.
Write down 4 as next digit of the result. 
Result so far: 30124.0
The remainder is 253 after subtracting 1032 from 1285.
Grab the next digit (0) from the dividend, add it to 253, then carry on: 2530 / 258

Moving on to step 8:
2530 divided by 258 is 9 with a remainder of 208.
The next digit of our result is 9. 
Result so far: 301249.0
The remainder is 208 after subtracting 2322 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 9:
When dividing 2080 by 258, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 301249.8
If we subtract 2064 from 2080, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
258 goes into 160 0 times with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 301249.8
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
258 goes into 1600 6 times with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 301249.806
Subtracting 1548 from 1600 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
If we divide 520 by 258, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 301249.8062
If we subtract 516 from 520, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
40 divided by 258 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 301249.8062
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
258 goes into 400 1 times with a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 301249.806201
Subtract 258 from 400 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 15:
The number 258 fits into 1420 5 times, leaving a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 301249.8062015
The remainder is 130 after subtracting 1290 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
258 can be fit into 1300 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 301249.80620155
Deduct 1290 from 1300 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.

The quotient of the division is 301249.80620155, and the remainder is 1e-08.
