70497464 divided by 258 
Our goal is to divide 70497464 by 258.

Advancing to step 1:
258 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 258

Going ahead to step 2:
The number 258 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 258

Going ahead to step 3:
The number 258 fits into 704 2 times, leaving a remainder of 188.
The next digit of our result is 2. 
Result so far: 2.0
If we take 516 away from 704, we end up with 188.
Include the next digit (9) from the dividend after 188, then repeat: 1889 / 258

Moving on to step 4:
If we divide 1889 by 258, we get 7 and a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 1806 from 1889 leaves us with 83.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 258

On to step 5:
If we divide 837 by 258, we get 3 and a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 273.0
If we subtract 774 from 837, we get 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 258

Step 6:
258 goes into 634 2 times with a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 2732.0
If we take 516 away from 634, we end up with 118.
Include the next digit (6) from the dividend after 118, then repeat: 1186 / 258

On to step 7:
258 can be fit into 1186 4 times, resulting in a remainder of 154.
The number 4 becomes the next digit in our result. 
Result so far: 27324.0
The remainder is 154 after subtracting 1032 from 1186.
Bring next digit (4) of the dividend behind the 154 and repeat the process: 1544 / 258

Let's proceed to step 8:
1544 divided by 258 is 5 with a remainder of 254.
Use 5 as the next digit of our solution. 
Result so far: 273245.0
Subtract 1290 from 1544 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 9:
258 goes into 2540 9 times with a remainder of 218.
Use 9 as the next digit of our solution. 
Result so far: 273245.9
If we subtract 2322 from 2540, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 10:
If we divide 2180 by 258, we get 8 and a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 273245.98
Deduct 2064 from 2180 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 11:
When dividing 1160 by 258, we get 4 with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 273245.984
If we subtract 1032 from 1160, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
If we divide 1280 by 258, we get 4 and a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 273245.9844
If we take 1032 away from 1280, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final result is 273245.9844 with a remainder of 0.00248.
