We're dividing 13481983 by 820 
The aim is to understand the frequency of 820 in 13481983.

Advancing to step 1:
820 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 820

Advancing to step 2:
13 divided by 820 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 820

Advancing to step 3:
When dividing 134 by 820, we get 0 with a remainder of 134.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 134 and we're left with 134.
Grab the next digit (8) from the dividend, add it to 134, then carry on: 1348 / 820

Going ahead to step 4:
When dividing 1348 by 820, we get 1 with a remainder of 528.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 820 from 1348, we get 528.
Append the next digit (1) from the dividend to 528 and continue with: 5281 / 820

Let's proceed to step 5:
If we divide 5281 by 820, we get 6 and a remainder of 361.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 361 after subtracting 4920 from 5281.
Fetch the next digit (9) from the dividend, attach it to 361 and continue: 3619 / 820

Let's proceed to step 6:
If we divide 3619 by 820, we get 4 and a remainder of 339.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
Subtract 3280 from 3619 to get 339.
Grab the next digit (8) from the dividend, add it to 339, then carry on: 3398 / 820

On to step 7:
820 goes into 3398 4 times with a remainder of 118.
The next digit of our result is 4. 
Result so far: 1644.0
Subtract 3280 from 3398 to get 118.
Append the next digit (3) from the dividend to 118 and continue with: 1183 / 820

Going ahead to step 8:
1183 divided by 820 is 1 with a remainder of 363.
Use 1 as the next digit of our solution. 
Result so far: 16441.0
Subtract 820 from 1183 to get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

On to step 9:
The number 820 fits into 3630 4 times, leaving a remainder of 350.
The next digit of our result is 4. 
Result so far: 16441.4
If we subtract 3280 from 3630, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 10:
820 can be fit into 3500 4 times, resulting in a remainder of 220.
Write down 4 as next digit of the result. 
Result so far: 16441.44
If we subtract 3280 from 3500, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 16441.44 and a remainder of 0.22.
