We look at the division of 30360010 by 820 
The aim is to understand the frequency of 820 in 30360010.

Let's proceed to step 1:
The number 820 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 820

Moving on to step 2:
The number 820 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 820

Going ahead to step 3:
820 goes into 303 0 times with a remainder of 303.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 303 after subtracting 0 from 303.
Bring next digit (6) of the dividend behind the 303 and repeat the process: 3036 / 820

Going ahead to step 4:
If we divide 3036 by 820, we get 3 and a remainder of 576.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 576 after subtracting 2460 from 3036.
Take the next digit (0) from the dividend and append it to 576, then repeat: 5760 / 820

Moving on to step 5:
The number 820 fits into 5760 7 times, leaving a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 5740 away from 5760, we end up with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 820

On to step 6:
200 divided by 820 is 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 370.0
Deduct 0 from 200 and we're left with 200.
Grab the next digit (1) from the dividend, add it to 200, then carry on: 2001 / 820

Let's proceed to step 7:
820 goes into 2001 2 times with a remainder of 361.
The next digit of our result is 2. 
Result so far: 3702.0
If we subtract 1640 from 2001, we get 361.
Grab the next digit (0) from the dividend, add it to 361, then carry on: 3610 / 820

Moving on to step 8:
820 goes into 3610 4 times with a remainder of 330.
The number 4 becomes the next digit in our result. 
Result so far: 37024.0
Subtract 3280 from 3610 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 9:
The number 820 fits into 3300 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 37024.4
Subtracting 3280 from 3300 leaves us with 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 10:
When dividing 200 by 820, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 37024.4
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
2000 divided by 820 is 2 with a remainder of 360.
Record the quotient 2 as the next digit in the result. 
Result so far: 37024.402
If we subtract 1640 from 2000, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 12:
When dividing 3600 by 820, we get 4 with a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 37024.4024
Subtract 3280 from 3600 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 13:
The number 820 fits into 3200 3 times, leaving a remainder of 740.
Write down 3 as next digit of the result. 
Result so far: 37024.40243
Subtracting 2460 from 3200 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Moving on to step 14:
820 can be fit into 7400 9 times, resulting in a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 37024.402439
The remainder is 20 after subtracting 7380 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
820 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 37024.402439
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 16:
If we divide 2000 by 820, we get 2 and a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 37024.40243902
Subtracting 1640 from 2000 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 37024.40243902 and a remainder of 3.6e-07.
