99917300 divided by 806 
Let's see how many times 806 fits into 99917300.

Advancing to step 1:
806 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 806

Going ahead to step 2:
806 can be fit into 99 0 times, resulting in a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Take the next digit (9) from the dividend and append it to 99, then repeat: 999 / 806

Moving on to step 3:
806 can be fit into 999 1 times, resulting in a remainder of 193.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 806 from 999 and we're left with 193.
Take the next digit (1) from the dividend and append it to 193, then repeat: 1931 / 806

Let's proceed to step 4:
806 goes into 1931 2 times with a remainder of 319.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1612 from 1931 and we're left with 319.
Grab the next digit (7) from the dividend, add it to 319, then carry on: 3197 / 806

Going ahead to step 5:
806 can be fit into 3197 3 times, resulting in a remainder of 779.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtract 2418 from 3197 to get 779.
Fetch the next digit (3) from the dividend, attach it to 779 and continue: 7793 / 806

Advancing to step 6:
The number 806 fits into 7793 9 times, leaving a remainder of 539.
The number 9 becomes the next digit in our result. 
Result so far: 1239.0
Subtracting 7254 from 7793 leaves us with 539.
Grab the next digit (0) from the dividend, add it to 539, then carry on: 5390 / 806

Moving on to step 7:
If we divide 5390 by 806, we get 6 and a remainder of 554.
Record the quotient 6 as the next digit in the result. 
Result so far: 12396.0
Subtracting 4836 from 5390 leaves us with 554.
Append the next digit (0) from the dividend to 554 and continue with: 5540 / 806

Step 8:
When dividing 5540 by 806, we get 6 with a remainder of 704.
Put 6 as the next digit of the answer. 
Result so far: 123966.0
The remainder is 704 after subtracting 4836 from 5540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 9:
If we divide 7040 by 806, we get 8 and a remainder of 592.
The next digit of our result is 8. 
Result so far: 123966.8
Subtracting 6448 from 7040 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 10:
806 can be fit into 5920 7 times, resulting in a remainder of 278.
The number 7 becomes the next digit in our result. 
Result so far: 123966.87
If we subtract 5642 from 5920, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 11:
When dividing 2780 by 806, we get 3 with a remainder of 362.
Use 3 as the next digit of our solution. 
Result so far: 123966.873
If we subtract 2418 from 2780, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 12:
When dividing 3620 by 806, we get 4 with a remainder of 396.
Write down 4 as next digit of the result. 
Result so far: 123966.8734
If we subtract 3224 from 3620, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 13:
If we divide 3960 by 806, we get 4 and a remainder of 736.
Put 4 as the next digit of the answer. 
Result so far: 123966.87344
Subtracting 3224 from 3960 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The final result is 123966.87344 with a remainder of 0.000736.
