53885375 ÷ 151 
The aim is to understand the frequency of 151 in 53885375.

Moving on to step 1:
If we divide 5 by 151, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 151

Moving on to step 2:
151 can be fit into 53 0 times, resulting in a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 151

Advancing to step 3:
The number 151 fits into 538 3 times, leaving a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 453 away from 538, we end up with 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 151

On to step 4:
The number 151 fits into 858 5 times, leaving a remainder of 103.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtracting 755 from 858 leaves us with 103.
Append the next digit (5) from the dividend to 103 and continue with: 1035 / 151

Moving on to step 5:
The number 151 fits into 1035 6 times, leaving a remainder of 129.
The next digit of our result is 6. 
Result so far: 356.0
If we subtract 906 from 1035, we get 129.
Take the next digit (3) from the dividend and append it to 129, then repeat: 1293 / 151

Going ahead to step 6:
When dividing 1293 by 151, we get 8 with a remainder of 85.
Use 8 as the next digit of our solution. 
Result so far: 3568.0
The remainder is 85 after subtracting 1208 from 1293.
Take the next digit (7) from the dividend and append it to 85, then repeat: 857 / 151

Moving on to step 7:
When dividing 857 by 151, we get 5 with a remainder of 102.
Record the quotient 5 as the next digit in the result. 
Result so far: 35685.0
The remainder is 102 after subtracting 755 from 857.
Grab the next digit (5) from the dividend, add it to 102, then carry on: 1025 / 151

Advancing to step 8:
The number 151 fits into 1025 6 times, leaving a remainder of 119.
Record the quotient 6 as the next digit in the result. 
Result so far: 356856.0
Subtracting 906 from 1025 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 9:
1190 divided by 151 is 7 with a remainder of 133.
Record the quotient 7 as the next digit in the result. 
Result so far: 356856.7
Subtract 1057 from 1190 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 10:
151 goes into 1330 8 times with a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 356856.78
If we subtract 1208 from 1330, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 11:
When dividing 1220 by 151, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 356856.788
If we subtract 1208 from 1220, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 356856.788 and a remainder of 0.0012.
