We look at the division of 886351 by 54 
The aim is to understand the frequency of 54 in 886351.

Going ahead to step 1:
When dividing 8 by 54, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 54

Advancing to step 2:
When dividing 88 by 54, we get 1 with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 54 from 88 and we're left with 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 54

On to step 3:
When dividing 346 by 54, we get 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 324 away from 346, we end up with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 54

Advancing to step 4:
223 divided by 54 is 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 164.0
Subtract 216 from 223 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 54

Let's proceed to step 5:
The number 54 fits into 75 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1641.0
The remainder is 21 after subtracting 54 from 75.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 54

Moving on to step 6:
54 can be fit into 211 3 times, resulting in a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 16413.0
The remainder is 49 after subtracting 162 from 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
54 can be fit into 490 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 16413.9
The remainder is 4 after subtracting 486 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 54 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 16413.9
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
The number 54 fits into 400 7 times, leaving a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 16413.907
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
When dividing 220 by 54, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 16413.9074
If we take 216 away from 220, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
54 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 16413.9074
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
When dividing 400 by 54, we get 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 16413.907407
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
220 divided by 54 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 16413.9074074
If we take 216 away from 220, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
54 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 16413.9074074
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 16413.9074074 and a remainder of 4e-08.
