99188870 divided by 306 
We want to figure out the number of times 99188870 can be divided by 306.

Let's proceed to step 1:
306 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 306

On to step 2:
306 can be fit into 99 0 times, resulting in a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Fetch the next digit (1) from the dividend, attach it to 99 and continue: 991 / 306

Advancing to step 3:
The number 306 fits into 991 3 times, leaving a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 918 from 991 to get 73.
Fetch the next digit (8) from the dividend, attach it to 73 and continue: 738 / 306

Step 4:
When dividing 738 by 306, we get 2 with a remainder of 126.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 612 away from 738, we end up with 126.
Fetch the next digit (8) from the dividend, attach it to 126 and continue: 1268 / 306

Step 5:
306 can be fit into 1268 4 times, resulting in a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 324.0
If we take 1224 away from 1268, we end up with 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 306

Moving on to step 6:
The number 306 fits into 448 1 times, leaving a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 3241.0
The remainder is 142 after subtracting 306 from 448.
Bring next digit (7) of the dividend behind the 142 and repeat the process: 1427 / 306

Moving on to step 7:
The number 306 fits into 1427 4 times, leaving a remainder of 203.
Record the quotient 4 as the next digit in the result. 
Result so far: 32414.0
Deduct 1224 from 1427 and we're left with 203.
Take the next digit (0) from the dividend and append it to 203, then repeat: 2030 / 306

On to step 8:
2030 divided by 306 is 6 with a remainder of 194.
The next digit of our result is 6. 
Result so far: 324146.0
If we subtract 1836 from 2030, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 9:
The number 306 fits into 1940 6 times, leaving a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 324146.6
Subtract 1836 from 1940 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 10:
306 goes into 1040 3 times with a remainder of 122.
Record the quotient 3 as the next digit in the result. 
Result so far: 324146.63
If we subtract 918 from 1040, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 11:
306 can be fit into 1220 3 times, resulting in a remainder of 302.
Use 3 as the next digit of our solution. 
Result so far: 324146.633
Subtracting 918 from 1220 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

The quotient of the division is 324146.633, and the remainder is 0.0302.
