98566458 divided by 668 
We want to divide 98566458 by 668.

Step 1:
The number 668 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 668

Let's proceed to step 2:
98 divided by 668 is 0 with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Fetch the next digit (5) from the dividend, attach it to 98 and continue: 985 / 668

Going ahead to step 3:
If we divide 985 by 668, we get 1 and a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 668 from 985 to get 317.
Include the next digit (6) from the dividend after 317, then repeat: 3176 / 668

Let's proceed to step 4:
668 can be fit into 3176 4 times, resulting in a remainder of 504.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 2672 from 3176, we get 504.
Take the next digit (6) from the dividend and append it to 504, then repeat: 5046 / 668

Step 5:
The number 668 fits into 5046 7 times, leaving a remainder of 370.
Use 7 as the next digit of our solution. 
Result so far: 147.0
If we subtract 4676 from 5046, we get 370.
Grab the next digit (4) from the dividend, add it to 370, then carry on: 3704 / 668

Moving on to step 6:
668 goes into 3704 5 times with a remainder of 364.
Put 5 as the next digit of the answer. 
Result so far: 1475.0
Subtract 3340 from 3704 to get 364.
Bring next digit (5) of the dividend behind the 364 and repeat the process: 3645 / 668

On to step 7:
3645 divided by 668 is 5 with a remainder of 305.
The next digit of our result is 5. 
Result so far: 14755.0
Deduct 3340 from 3645 and we're left with 305.
Include the next digit (8) from the dividend after 305, then repeat: 3058 / 668

Advancing to step 8:
If we divide 3058 by 668, we get 4 and a remainder of 386.
Write down 4 as next digit of the result. 
Result so far: 147554.0
Subtracting 2672 from 3058 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 9:
The number 668 fits into 3860 5 times, leaving a remainder of 520.
The next digit of our result is 5. 
Result so far: 147554.5
Subtract 3340 from 3860 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 10:
The number 668 fits into 5200 7 times, leaving a remainder of 524.
Put 7 as the next digit of the answer. 
Result so far: 147554.57
Subtracting 4676 from 5200 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 11:
If we divide 5240 by 668, we get 7 and a remainder of 564.
Use 7 as the next digit of our solution. 
Result so far: 147554.577
If we take 4676 away from 5240, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

In conclusion, the division gives 147554.577 with a balance of 0.0564.
