We look at the division of 86946113 by 306 
The aim is to understand the frequency of 306 in 86946113.

On to step 1:
8 divided by 306 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 306

Advancing to step 2:
When dividing 86 by 306, we get 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 306

On to step 3:
The number 306 fits into 869 2 times, leaving a remainder of 257.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 257 after subtracting 612 from 869.
Include the next digit (4) from the dividend after 257, then repeat: 2574 / 306

Step 4:
If we divide 2574 by 306, we get 8 and a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 2448 from 2574 leaves us with 126.
Take the next digit (6) from the dividend and append it to 126, then repeat: 1266 / 306

Moving on to step 5:
306 can be fit into 1266 4 times, resulting in a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 284.0
Subtracting 1224 from 1266 leaves us with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 306

On to step 6:
If we divide 421 by 306, we get 1 and a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 2841.0
The remainder is 115 after subtracting 306 from 421.
Grab the next digit (1) from the dividend, add it to 115, then carry on: 1151 / 306

Let's proceed to step 7:
306 goes into 1151 3 times with a remainder of 233.
Put 3 as the next digit of the answer. 
Result so far: 28413.0
If we take 918 away from 1151, we end up with 233.
Include the next digit (3) from the dividend after 233, then repeat: 2333 / 306

Let's proceed to step 8:
306 goes into 2333 7 times with a remainder of 191.
The next digit of our result is 7. 
Result so far: 284137.0
If we take 2142 away from 2333, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Going ahead to step 9:
306 can be fit into 1910 6 times, resulting in a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 284137.6
Deduct 1836 from 1910 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
If we divide 740 by 306, we get 2 and a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 284137.62
Subtracting 612 from 740 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 11:
The number 306 fits into 1280 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 284137.624
Deduct 1224 from 1280 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
If we divide 560 by 306, we get 1 and a remainder of 254.
Write down 1 as next digit of the result. 
Result so far: 284137.6241
The remainder is 254 after subtracting 306 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 13:
When dividing 2540 by 306, we get 8 with a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 284137.62418
Deduct 2448 from 2540 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 14:
306 goes into 920 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 284137.624183
Subtracting 918 from 920 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 15:
20 divided by 306 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 284137.624183
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 16:
When dividing 200 by 306, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 284137.624183
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 284137.624183 with a balance of 2e-07.
