We're dividing 78720042 by 164 
The aim is to understand the frequency of 164 in 78720042.

Advancing to step 1:
7 divided by 164 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 164

Let's proceed to step 2:
The number 164 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 164

Advancing to step 3:
If we divide 787 by 164, we get 4 and a remainder of 131.
The next digit of our result is 4. 
Result so far: 4.0
If we take 656 away from 787, we end up with 131.
Take the next digit (2) from the dividend and append it to 131, then repeat: 1312 / 164

Going ahead to step 4:
164 goes into 1312 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 48.0
Deduct 1312 from 1312 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 164

Going ahead to step 5:
0 divided by 164 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 480.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 164

On to step 6:
164 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4800.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 164

Going ahead to step 7:
The number 164 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 48000.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 164

Going ahead to step 8:
164 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 480000.0
The remainder is 42 after subtracting 0 from 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
The number 164 fits into 420 2 times, leaving a remainder of 92.
The next digit of our result is 2. 
Result so far: 480000.2
If we subtract 328 from 420, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
920 divided by 164 is 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 480000.25
Subtracting 820 from 920 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
If we divide 1000 by 164, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 480000.256
Subtract 984 from 1000 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
164 can be fit into 160 0 times, resulting in a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 480000.256
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
164 can be fit into 1600 9 times, resulting in a remainder of 124.
The next digit of our result is 9. 
Result so far: 480000.25609
Deduct 1476 from 1600 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 14:
164 can be fit into 1240 7 times, resulting in a remainder of 92.
Use 7 as the next digit of our solution. 
Result so far: 480000.256097
Subtract 1148 from 1240 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 15:
164 goes into 920 5 times with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 480000.2560975
Subtract 820 from 920 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 16:
164 can be fit into 1000 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 480000.25609756
Subtracting 984 from 1000 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 480000.25609756 with a remainder of 1.6e-08.
