We're dividing 98855251 by 258 
We want to figure out the number of times 98855251 can be divided by 258.

Let's proceed to step 1:
9 divided by 258 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 258

Let's proceed to step 2:
258 goes into 98 0 times with a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Bring next digit (8) of the dividend behind the 98 and repeat the process: 988 / 258

Going ahead to step 3:
When dividing 988 by 258, we get 3 with a remainder of 214.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 774 from 988, we get 214.
Fetch the next digit (5) from the dividend, attach it to 214 and continue: 2145 / 258

Going ahead to step 4:
258 goes into 2145 8 times with a remainder of 81.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 2064 away from 2145, we end up with 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 258

Moving on to step 5:
258 can be fit into 815 3 times, resulting in a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 383.0
Deduct 774 from 815 and we're left with 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 258

Advancing to step 6:
When dividing 412 by 258, we get 1 with a remainder of 154.
Record the quotient 1 as the next digit in the result. 
Result so far: 3831.0
Subtract 258 from 412 to get 154.
Append the next digit (5) from the dividend to 154 and continue with: 1545 / 258

Going ahead to step 7:
When dividing 1545 by 258, we get 5 with a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 38315.0
If we subtract 1290 from 1545, we get 255.
Fetch the next digit (1) from the dividend, attach it to 255 and continue: 2551 / 258

Step 8:
2551 divided by 258 is 9 with a remainder of 229.
The number 9 becomes the next digit in our result. 
Result so far: 383159.0
The remainder is 229 after subtracting 2322 from 2551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Moving on to step 9:
If we divide 2290 by 258, we get 8 and a remainder of 226.
The next digit of our result is 8. 
Result so far: 383159.8
Subtract 2064 from 2290 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 10:
The number 258 fits into 2260 8 times, leaving a remainder of 196.
The next digit of our result is 8. 
Result so far: 383159.88
If we take 2064 away from 2260, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Our division results in 383159.88 with a remaining 0.196.
