8733140 divided by 306 
The aim is to understand the frequency of 306 in 8733140.

On to step 1:
306 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 306

Advancing to step 2:
306 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Bring next digit (3) of the dividend behind the 87 and repeat the process: 873 / 306

Advancing to step 3:
873 divided by 306 is 2 with a remainder of 261.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 612 from 873 leaves us with 261.
Bring next digit (3) of the dividend behind the 261 and repeat the process: 2613 / 306

On to step 4:
If we divide 2613 by 306, we get 8 and a remainder of 165.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 2448 from 2613 and we're left with 165.
Include the next digit (1) from the dividend after 165, then repeat: 1651 / 306

Advancing to step 5:
1651 divided by 306 is 5 with a remainder of 121.
Write down 5 as next digit of the result. 
Result so far: 285.0
Subtract 1530 from 1651 to get 121.
Fetch the next digit (4) from the dividend, attach it to 121 and continue: 1214 / 306

Advancing to step 6:
1214 divided by 306 is 3 with a remainder of 296.
Put 3 as the next digit of the answer. 
Result so far: 2853.0
The remainder is 296 after subtracting 918 from 1214.
Append the next digit (0) from the dividend to 296 and continue with: 2960 / 306

Let's proceed to step 7:
306 can be fit into 2960 9 times, resulting in a remainder of 206.
The next digit of our result is 9. 
Result so far: 28539.0
If we take 2754 away from 2960, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 8:
306 goes into 2060 6 times with a remainder of 224.
Record the quotient 6 as the next digit in the result. 
Result so far: 28539.6
If we take 1836 away from 2060, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 9:
If we divide 2240 by 306, we get 7 and a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 28539.67
Deduct 2142 from 2240 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
980 divided by 306 is 3 with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 28539.673
Subtract 918 from 980 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
306 can be fit into 620 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 28539.6732
If we take 612 away from 620, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
If we divide 80 by 306, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 28539.6732
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
306 can be fit into 800 2 times, resulting in a remainder of 188.
Use 2 as the next digit of our solution. 
Result so far: 28539.673202
If we subtract 612 from 800, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 14:
The number 306 fits into 1880 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 28539.6732026
Subtract 1836 from 1880 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 15:
306 can be fit into 440 1 times, resulting in a remainder of 134.
The next digit of our result is 1. 
Result so far: 28539.67320261
If we subtract 306 from 440, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The final result is 28539.67320261 with a remainder of 1.34e-07.
