8098213 divided by 258 
We want to figure out the number of times 8098213 can be divided by 258.

Let's proceed to step 1:
The number 258 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 258

Step 2:
If we divide 80 by 258, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 258

On to step 3:
When dividing 809 by 258, we get 3 with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 774 from 809 to get 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 258

Step 4:
358 divided by 258 is 1 with a remainder of 100.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 258 from 358 to get 100.
Fetch the next digit (2) from the dividend, attach it to 100 and continue: 1002 / 258

Going ahead to step 5:
258 can be fit into 1002 3 times, resulting in a remainder of 228.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
Deduct 774 from 1002 and we're left with 228.
Include the next digit (1) from the dividend after 228, then repeat: 2281 / 258

On to step 6:
258 can be fit into 2281 8 times, resulting in a remainder of 217.
Put 8 as the next digit of the answer. 
Result so far: 3138.0
Subtracting 2064 from 2281 leaves us with 217.
Bring next digit (3) of the dividend behind the 217 and repeat the process: 2173 / 258

On to step 7:
258 goes into 2173 8 times with a remainder of 109.
Use 8 as the next digit of our solution. 
Result so far: 31388.0
Subtract 2064 from 2173 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 8:
The number 258 fits into 1090 4 times, leaving a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 31388.4
If we subtract 1032 from 1090, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
The number 258 fits into 580 2 times, leaving a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 31388.42
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
258 goes into 640 2 times with a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 31388.422
Subtracting 516 from 640 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Our division results in 31388.422 with a remaining 0.0124.
