Let's divide 39719456 by 820
The aim is to understand the frequency of 820 in 39719456.

Step 1:
When dividing 3 by 820, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 820

On to step 2:
If we divide 39 by 820, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 820

Going ahead to step 3:
The number 820 fits into 397 0 times, leaving a remainder of 397.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 397, we end up with 397.
Fetch the next digit (1) from the dividend, attach it to 397 and continue: 3971 / 820

Let's proceed to step 4:
If we divide 3971 by 820, we get 4 and a remainder of 691.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3280 away from 3971, we end up with 691.
Append the next digit (9) from the dividend to 691 and continue with: 6919 / 820

Let's proceed to step 5:
The number 820 fits into 6919 8 times, leaving a remainder of 359.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 6560 from 6919 leaves us with 359.
Fetch the next digit (4) from the dividend, attach it to 359 and continue: 3594 / 820

Advancing to step 6:
When dividing 3594 by 820, we get 4 with a remainder of 314.
The next digit of our result is 4. 
Result so far: 484.0
The remainder is 314 after subtracting 3280 from 3594.
Bring next digit (5) of the dividend behind the 314 and repeat the process: 3145 / 820

Advancing to step 7:
When dividing 3145 by 820, we get 3 with a remainder of 685.
The number 3 becomes the next digit in our result. 
Result so far: 4843.0
Subtracting 2460 from 3145 leaves us with 685.
Fetch the next digit (6) from the dividend, attach it to 685 and continue: 6856 / 820

Let's proceed to step 8:
When dividing 6856 by 820, we get 8 with a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 48438.0
The remainder is 296 after subtracting 6560 from 6856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 9:
The number 820 fits into 2960 3 times, leaving a remainder of 500.
Put 3 as the next digit of the answer. 
Result so far: 48438.3
Deduct 2460 from 2960 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 10:
The number 820 fits into 5000 6 times, leaving a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 48438.36
Deduct 4920 from 5000 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
820 can be fit into 800 0 times, resulting in a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 48438.36
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 12:
820 can be fit into 8000 9 times, resulting in a remainder of 620.
Record the quotient 9 as the next digit in the result. 
Result so far: 48438.3609
Subtract 7380 from 8000 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 13:
820 goes into 6200 7 times with a remainder of 460.
Put 7 as the next digit of the answer. 
Result so far: 48438.36097
Subtract 5740 from 6200 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 14:
4600 divided by 820 is 5 with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 48438.360975
Subtracting 4100 from 4600 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 15:
820 goes into 5000 6 times with a remainder of 80.
The next digit of our result is 6. 
Result so far: 48438.3609756
If we subtract 4920 from 5000, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
If we divide 800 by 820, we get 0 and a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 48438.3609756
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Our division results in 48438.3609756 with a remaining 8e-07.
