Let's divide 98040803 by 866
We want to figure out the number of times 98040803 can be divided by 866.

On to step 1:
When dividing 9 by 866, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 866

Step 2:
The number 866 fits into 98 0 times, leaving 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.
Grab the next digit (0) from the dividend, add it to 98, then carry on: 980 / 866

Going ahead to step 3:
When dividing 980 by 866, we get 1 with a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 866 from 980, we get 114.
Take the next digit (4) from the dividend and append it to 114, then repeat: 1144 / 866

Moving on to step 4:
The number 866 fits into 1144 1 times, leaving a remainder of 278.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 866 from 1144 and we're left with 278.
Grab the next digit (0) from the dividend, add it to 278, then carry on: 2780 / 866

Moving on to step 5:
When dividing 2780 by 866, we get 3 with a remainder of 182.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
If we take 2598 away from 2780, we end up with 182.
Bring next digit (8) of the dividend behind the 182 and repeat the process: 1828 / 866

Step 6:
866 goes into 1828 2 times with a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 1132.0
If we take 1732 away from 1828, we end up with 96.
Take the next digit (0) from the dividend and append it to 96, then repeat: 960 / 866

Advancing to step 7:
866 goes into 960 1 times with a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 11321.0
If we take 866 away from 960, we end up with 94.
Bring next digit (3) of the dividend behind the 94 and repeat the process: 943 / 866

Step 8:
866 can be fit into 943 1 times, resulting in a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 113211.0
Subtracting 866 from 943 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
866 can be fit into 770 0 times, resulting in a remainder of 770.
The number 0 becomes the next digit in our result. 
Result so far: 113211.0
Deduct 0 from 770 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Let's proceed to step 10:
When dividing 7700 by 866, we get 8 with a remainder of 772.
Use 8 as the next digit of our solution. 
Result so far: 113211.08
The remainder is 772 after subtracting 6928 from 7700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Advancing to step 11:
866 goes into 7720 8 times with a remainder of 792.
Record the quotient 8 as the next digit in the result. 
Result so far: 113211.088
If we take 6928 away from 7720, we end up with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

After the division, we end up with 113211.088 and a remainder of 0.0792.
