We look at the division of 50393132 by 820 
The aim is to understand the frequency of 820 in 50393132.

On to step 1:
5 divided by 820 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 820

Going ahead to step 2:
820 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 820

Let's proceed to step 3:
820 goes into 503 0 times with a remainder of 503.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 503 and we're left with 503.
Include the next digit (9) from the dividend after 503, then repeat: 5039 / 820

Advancing to step 4:
When dividing 5039 by 820, we get 6 with a remainder of 119.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 4920 from 5039 leaves us with 119.
Append the next digit (3) from the dividend to 119 and continue with: 1193 / 820

Let's proceed to step 5:
When dividing 1193 by 820, we get 1 with a remainder of 373.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Subtracting 820 from 1193 leaves us with 373.
Append the next digit (1) from the dividend to 373 and continue with: 3731 / 820

Going ahead to step 6:
When dividing 3731 by 820, we get 4 with a remainder of 451.
Use 4 as the next digit of our solution. 
Result so far: 614.0
If we subtract 3280 from 3731, we get 451.
Append the next digit (3) from the dividend to 451 and continue with: 4513 / 820

Step 7:
The number 820 fits into 4513 5 times, leaving a remainder of 413.
The next digit of our result is 5. 
Result so far: 6145.0
Subtract 4100 from 4513 to get 413.
Fetch the next digit (2) from the dividend, attach it to 413 and continue: 4132 / 820

Advancing to step 8:
When dividing 4132 by 820, we get 5 with a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 61455.0
If we subtract 4100 from 4132, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
The number 820 fits into 320 0 times, leaving a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 61455.0
Subtract 0 from 320 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.

Let's proceed to step 10:
820 goes into 3200 3 times with a remainder of 740.
Put 3 as the next digit of the answer. 
Result so far: 61455.03
If we take 2460 away from 3200, we end up 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.

On to step 11:
The number 820 fits into 7400 9 times, leaving a remainder of 20.
The next digit of our result is 9. 
Result so far: 61455.039
If we subtract 7380 from 7400, we get 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 12:
The number 820 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 61455.039
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.

On to step 13:
If we divide 2000 by 820, we get 2 and a remainder of 360.
The next digit of our result is 2. 
Result so far: 61455.03902
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.

Let's proceed to step 14:
820 can be fit into 3600 4 times, resulting in a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 61455.039024
If we take 3280 away from 3600, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 15:
3200 divided by 820 is 3 with a remainder of 740.
Write down 3 as next digit of the result. 
Result so far: 61455.0390243
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.

Going ahead to step 16:
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: 61455.03902439
If we subtract 7380 from 7400, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 61455.03902439 and a remainder of 2e-08.
