The aim is to understand the frequency of 820 in 39110066.

Step 1:
3 divided by 820 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 820

Advancing to step 2:
820 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 820

Going ahead to step 3:
820 can be fit into 391 0 times, resulting in a remainder of 391.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 391 leaves us with 391.
Grab the next digit (1) from the dividend, add it to 391, then carry on: 3911 / 820

Moving on to step 4:
When dividing 3911 by 820, we get 4 with a remainder of 631.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3280 from 3911 and we're left with 631.
Take the next digit (0) from the dividend and append it to 631, then repeat: 6310 / 820

Let's proceed to step 5:
6310 divided by 820 is 7 with a remainder of 570.
Write down 7 as next digit of the result. 
Result so far: 47.0
Deduct 5740 from 6310 and we're left with 570.
Append the next digit (0) from the dividend to 570 and continue with: 5700 / 820

Let's proceed to step 6:
If we divide 5700 by 820, we get 6 and a remainder of 780.
The number 6 becomes the next digit in our result. 
Result so far: 476.0
If we take 4920 away from 5700, we end up with 780.
Append the next digit (6) from the dividend to 780 and continue with: 7806 / 820

Let's proceed to step 7:
7806 divided by 820 is 9 with a remainder of 426.
The number 9 becomes the next digit in our result. 
Result so far: 4769.0
If we take 7380 away from 7806, we end up with 426.
Grab the next digit (6) from the dividend, add it to 426, then carry on: 4266 / 820

Advancing to step 8:
820 can be fit into 4266 5 times, resulting in a remainder of 166.
Use 5 as the next digit of our solution. 
Result so far: 47695.0
Subtract 4100 from 4266 to 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 9:
When dividing 1660 by 820, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 47695.2
If we take 1640 away from 1660, we end up 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.

Advancing to step 10:
820 goes into 200 0 times with a remainder of 200.
The next digit of our result is 0. 
Result so far: 47695.2
Subtract 0 from 200 to 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.

Moving on to step 11:
The number 820 fits into 2000 2 times, leaving a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 47695.202
The remainder is 360 after subtracting 1640 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 12:
If we divide 3600 by 820, we get 4 and a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 47695.2024
If we subtract 3280 from 3600, we 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.

Advancing to step 13:
3200 divided by 820 is 3 with a remainder of 740.
Write down 3 as next digit of the result. 
Result so far: 47695.20243
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.

Advancing to step 14:
The number 820 fits into 7400 9 times, leaving a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 47695.202439
Subtracting 7380 from 7400 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.

Moving on to step 15:
When dividing 200 by 820, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 47695.202439
Subtract 0 from 200 to 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.

Step 16:
820 can be fit into 2000 2 times, resulting in a remainder of 360.
Use 2 as the next digit of our solution. 
Result so far: 47695.20243902
Deduct 1640 from 2000 and we're left 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.

In conclusion, the division gives 47695.20243902 with a balance of 3.6e-07.
