Let's divide 16405199 by 54
The aim is to understand the frequency of 54 in 16405199.

Moving on to step 1:
54 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 54

Advancing to step 2:
When dividing 16 by 54, we get 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 54

Advancing to step 3:
164 divided by 54 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 162 from 164, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 54

Moving on to step 4:
When dividing 20 by 54, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 54

Going ahead to step 5:
54 can be fit into 205 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 303.0
If we take 162 away from 205, we end up with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 54

On to step 6:
When dividing 431 by 54, we get 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 3037.0
If we subtract 378 from 431, we get 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 54

Moving on to step 7:
54 can be fit into 539 9 times, resulting in a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 30379.0
Subtracting 486 from 539 leaves us with 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 54

Advancing to step 8:
The number 54 fits into 539 9 times, leaving a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 303799.0
Subtracting 486 from 539 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
54 can be fit into 530 9 times, resulting in a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 303799.9
Deduct 486 from 530 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
54 goes into 440 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 303799.98
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
54 goes into 80 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 303799.981
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
54 can be fit into 260 4 times, resulting in a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 303799.9814
Subtracting 216 from 260 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
440 divided by 54 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 303799.98148
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
When dividing 80 by 54, we get 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 303799.981481
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 15:
54 can be fit into 260 4 times, resulting in a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 303799.9814814
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 16:
If we divide 440 by 54, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 303799.98148148
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 303799.98148148, and the remainder is 8e-09.
