We look at the division of 22048170 by 306 
The aim is to understand the frequency of 306 in 22048170.

Step 1:
If we divide 2 by 306, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 306

Going ahead to step 2:
22 divided by 306 is 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 306

Advancing to step 3:
If we divide 220 by 306, we get 0 and a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 220, we get 220.
Bring next digit (4) of the dividend behind the 220 and repeat the process: 2204 / 306

On to step 4:
The number 306 fits into 2204 7 times, leaving a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 2142 away from 2204, we end up with 62.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 306

Moving on to step 5:
628 divided by 306 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we subtract 612 from 628, we get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 306

Moving on to step 6:
306 goes into 161 0 times with a remainder of 161.
Record the quotient 0 as the next digit in the result. 
Result so far: 720.0
The remainder is 161 after subtracting 0 from 161.
Grab the next digit (7) from the dividend, add it to 161, then carry on: 1617 / 306

Advancing to step 7:
If we divide 1617 by 306, we get 5 and a remainder of 87.
Record the quotient 5 as the next digit in the result. 
Result so far: 7205.0
Subtracting 1530 from 1617 leaves us with 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 306

Let's proceed to step 8:
When dividing 870 by 306, we get 2 with a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 72052.0
Subtract 612 from 870 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 9:
306 can be fit into 2580 8 times, resulting in a remainder of 132.
Put 8 as the next digit of the answer. 
Result so far: 72052.8
If we take 2448 away from 2580, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 10:
1320 divided by 306 is 4 with a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 72052.84
Deduct 1224 from 1320 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
306 can be fit into 960 3 times, resulting in a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 72052.843
If we subtract 918 from 960, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
The number 306 fits into 420 1 times, leaving a remainder of 114.
The number 1 becomes the next digit in our result. 
Result so far: 72052.8431
Subtracting 306 from 420 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 13:
1140 divided by 306 is 3 with a remainder of 222.
Write down 3 as next digit of the result. 
Result so far: 72052.84313
If we subtract 918 from 1140, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 14:
306 can be fit into 2220 7 times, resulting in a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 72052.843137
Deduct 2142 from 2220 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 15:
The number 306 fits into 780 2 times, leaving a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 72052.8431372
If we take 612 away from 780, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 16:
306 can be fit into 1680 5 times, resulting in a remainder of 150.
The next digit of our result is 5. 
Result so far: 72052.84313725
The remainder is 150 after subtracting 1530 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final outcome is 72052.84313725, with a leftover of 1.5e-07.
