Let's divide 64750423 by 306
The aim is to understand the frequency of 306 in 64750423.

Advancing to step 1:
If we divide 6 by 306, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 306

Advancing to step 2:
306 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 306

Moving on to step 3:
If we divide 647 by 306, we get 2 and a remainder of 35.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 612 from 647 to get 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 306

Step 4:
306 can be fit into 355 1 times, resulting in a remainder of 49.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 306 from 355, we get 49.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 306

Moving on to step 5:
When dividing 490 by 306, we get 1 with a remainder of 184.
The number 1 becomes the next digit in our result. 
Result so far: 211.0
If we subtract 306 from 490, we get 184.
Fetch the next digit (4) from the dividend, attach it to 184 and continue: 1844 / 306

Advancing to step 6:
306 goes into 1844 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 2116.0
The remainder is 8 after subtracting 1836 from 1844.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 306

Advancing to step 7:
If we divide 82 by 306, we get 0 and a remainder of 82.
The next digit of our result is 0. 
Result so far: 21160.0
Deduct 0 from 82 and we're left with 82.
Include the next digit (3) from the dividend after 82, then repeat: 823 / 306

On to step 8:
When dividing 823 by 306, we get 2 with a remainder of 211.
Put 2 as the next digit of the answer. 
Result so far: 211602.0
Subtract 612 from 823 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 9:
306 can be fit into 2110 6 times, resulting in a remainder of 274.
The next digit of our result is 6. 
Result so far: 211602.6
Deduct 1836 from 2110 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 10:
2740 divided by 306 is 8 with a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 211602.68
The remainder is 292 after subtracting 2448 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 11:
When dividing 2920 by 306, we get 9 with a remainder of 166.
Write down 9 as next digit of the result. 
Result so far: 211602.689
If we subtract 2754 from 2920, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 12:
When dividing 1660 by 306, we get 5 with a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 211602.6895
The remainder is 130 after subtracting 1530 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 13:
The number 306 fits into 1300 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 211602.68954
The remainder is 76 after subtracting 1224 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
If we divide 760 by 306, we get 2 and a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 211602.689542
If we take 612 away from 760, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 15:
306 can be fit into 1480 4 times, resulting in a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 211602.6895424
The remainder is 256 after subtracting 1224 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 16:
306 goes into 2560 8 times with a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 211602.68954248
The remainder is 112 after subtracting 2448 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 211602.68954248 and a remainder of 1.12e-07.
