71356169 ÷ 306 
The aim is to understand the frequency of 306 in 71356169.

Moving on to step 1:
306 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 306

Advancing to step 2:
When dividing 71 by 306, we get 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 306

Step 3:
The number 306 fits into 713 2 times, leaving a remainder of 101.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 612 from 713 leaves us with 101.
Grab the next digit (5) from the dividend, add it to 101, then carry on: 1015 / 306

On to step 4:
The number 306 fits into 1015 3 times, leaving a remainder of 97.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 918 from 1015 to get 97.
Grab the next digit (6) from the dividend, add it to 97, then carry on: 976 / 306

Moving on to step 5:
When dividing 976 by 306, we get 3 with a remainder of 58.
The next digit of our result is 3. 
Result so far: 233.0
Subtract 918 from 976 to get 58.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 306

Step 6:
581 divided by 306 is 1 with a remainder of 275.
Use 1 as the next digit of our solution. 
Result so far: 2331.0
If we subtract 306 from 581, we get 275.
Bring next digit (6) of the dividend behind the 275 and repeat the process: 2756 / 306

Moving on to step 7:
If we divide 2756 by 306, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 23319.0
If we take 2754 away from 2756, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 306

On to step 8:
306 goes into 29 0 times with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 233190.0
If we subtract 0 from 29, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
306 goes into 290 0 times with a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 233190.0
Subtract 0 from 290 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 10:
306 can be fit into 2900 9 times, resulting in a remainder of 146.
The number 9 becomes the next digit in our result. 
Result so far: 233190.09
If we subtract 2754 from 2900, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 11:
If we divide 1460 by 306, we get 4 and a remainder of 236.
The number 4 becomes the next digit in our result. 
Result so far: 233190.094
Deduct 1224 from 1460 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 12:
When dividing 2360 by 306, we get 7 with a remainder of 218.
Record the quotient 7 as the next digit in the result. 
Result so far: 233190.0947
Subtract 2142 from 2360 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 13:
If we divide 2180 by 306, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 233190.09477
The remainder is 38 after subtracting 2142 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 233190.09477, and the remainder is 3.8e-05.
