We divide 13125077 by 820
The aim is to understand the frequency of 820 in 13125077.

Going ahead to step 1:
820 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 820

Step 2:
When dividing 13 by 820, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 820

Going ahead to step 3:
The number 820 fits into 131 0 times, leaving a remainder of 131.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 131, we end up with 131.
Take the next digit (2) from the dividend and append it to 131, then repeat: 1312 / 820

Going ahead to step 4:
If we divide 1312 by 820, we get 1 and a remainder of 492.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 820 from 1312 to get 492.
Bring next digit (5) of the dividend behind the 492 and repeat the process: 4925 / 820

Step 5:
If we divide 4925 by 820, we get 6 and a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 5 after subtracting 4920 from 4925.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 820

Advancing to step 6:
820 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
If we subtract 0 from 50, we get 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 820

Going ahead to step 7:
507 divided by 820 is 0 with a remainder of 507.
The number 0 becomes the next digit in our result. 
Result so far: 1600.0
The remainder is 507 after subtracting 0 from 507.
Fetch the next digit (7) from the dividend, attach it to 507 and continue: 5077 / 820

Let's proceed to step 8:
820 can be fit into 5077 6 times, resulting in a remainder of 157.
The number 6 becomes the next digit in our result. 
Result so far: 16006.0
Subtract 4920 from 5077 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 9:
820 goes into 1570 1 times with a remainder of 750.
The next digit of our result is 1. 
Result so far: 16006.1
If we subtract 820 from 1570, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 10:
7500 divided by 820 is 9 with a remainder of 120.
The number 9 becomes the next digit in our result. 
Result so far: 16006.19
If we subtract 7380 from 7500, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 11:
The number 820 fits into 1200 1 times, leaving a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 16006.191
If we take 820 away from 1200, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 12:
When dividing 3800 by 820, we get 4 with a remainder of 520.
The next digit of our result is 4. 
Result so far: 16006.1914
If we subtract 3280 from 3800, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 13:
820 goes into 5200 6 times with a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 16006.19146
The remainder is 280 after subtracting 4920 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 14:
820 goes into 2800 3 times with a remainder of 340.
The next digit of our result is 3. 
Result so far: 16006.191463
Subtract 2460 from 2800 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
When dividing 3400 by 820, we get 4 with a remainder of 120.
The next digit of our result is 4. 
Result so far: 16006.1914634
Subtract 3280 from 3400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 16:
820 goes into 1200 1 times with a remainder of 380.
Use 1 as the next digit of our solution. 
Result so far: 16006.19146341
Subtract 820 from 1200 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 16006.19146341 with a remainder of 3.8e-07.
