We're dividing 15797393 by 486 
The aim is to understand the frequency of 486 in 15797393.

On to step 1:
The number 486 fits into 1 0 times, leaving 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.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 486

Moving on to step 2:
486 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 486

Going ahead to step 3:
If we divide 157 by 486, we get 0 and a remainder of 157.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 157 leaves us with 157.
Take the next digit (9) from the dividend and append it to 157, then repeat: 1579 / 486

Let's proceed to step 4:
1579 divided by 486 is 3 with a remainder of 121.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 1458 from 1579 leaves us with 121.
Append the next digit (7) from the dividend to 121 and continue with: 1217 / 486

Step 5:
486 goes into 1217 2 times with a remainder of 245.
The next digit of our result is 2. 
Result so far: 32.0
Deduct 972 from 1217 and we're left with 245.
Grab the next digit (3) from the dividend, add it to 245, then carry on: 2453 / 486

Moving on to step 6:
486 can be fit into 2453 5 times, resulting in a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 325.0
If we subtract 2430 from 2453, we get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 486

Step 7:
239 divided by 486 is 0 with a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 3250.0
If we take 0 away from 239, we end up with 239.
Grab the next digit (3) from the dividend, add it to 239, then carry on: 2393 / 486

Advancing to step 8:
486 goes into 2393 4 times with a remainder of 449.
Use 4 as the next digit of our solution. 
Result so far: 32504.0
The remainder is 449 after subtracting 1944 from 2393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Moving on to step 9:
The number 486 fits into 4490 9 times, leaving a remainder of 116.
Put 9 as the next digit of the answer. 
Result so far: 32504.9
Subtracting 4374 from 4490 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
486 can be fit into 1160 2 times, resulting in a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 32504.92
If we take 972 away from 1160, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 11:
1880 divided by 486 is 3 with a remainder of 422.
Record the quotient 3 as the next digit in the result. 
Result so far: 32504.923
Subtract 1458 from 1880 to get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Advancing to step 12:
The number 486 fits into 4220 8 times, leaving a remainder of 332.
Use 8 as the next digit of our solution. 
Result so far: 32504.9238
Subtracting 3888 from 4220 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 13:
If we divide 3320 by 486, we get 6 and a remainder of 404.
Use 6 as the next digit of our solution. 
Result so far: 32504.92386
If we subtract 2916 from 3320, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 14:
If we divide 4040 by 486, we get 8 and a remainder of 152.
Put 8 as the next digit of the answer. 
Result so far: 32504.923868
Subtract 3888 from 4040 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 15:
486 can be fit into 1520 3 times, resulting in a remainder of 62.
The next digit of our result is 3. 
Result so far: 32504.9238683
If we subtract 1458 from 1520, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 16:
620 divided by 486 is 1 with a remainder of 134.
The next digit of our result is 1. 
Result so far: 32504.92386831
Subtracting 486 from 620 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The final outcome is 32504.92386831, with a leftover of 1.34e-07.
