45956581 ÷ 54 
The aim is to understand the frequency of 54 in 45956581.

Let's proceed to step 1:
The number 54 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 54

On to step 2:
54 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 54

On to step 3:
The number 54 fits into 459 8 times, leaving a remainder of 27.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 432 from 459, we get 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 54

Let's proceed to step 4:
If we divide 275 by 54, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 85.0
The remainder is 5 after subtracting 270 from 275.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 54

Advancing to step 5:
54 goes into 56 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 851.0
The remainder is 2 after subtracting 54 from 56.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 54

Let's proceed to step 6:
54 goes into 25 0 times with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 8510.0
Subtract 0 from 25 to get 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 54

On to step 7:
The number 54 fits into 258 4 times, leaving a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 85104.0
Subtracting 216 from 258 leaves us with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 54

Advancing to step 8:
When dividing 421 by 54, we get 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 851047.0
If we subtract 378 from 421, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
The number 54 fits into 430 7 times, leaving a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 851047.7
Deduct 378 from 430 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
If we divide 520 by 54, we get 9 and a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 851047.79
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
The number 54 fits into 340 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 851047.796
Subtract 324 from 340 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.

Going ahead to step 12:
54 goes into 160 2 times with a remainder of 52.
The next digit of our result is 2. 
Result so far: 851047.7962
If we take 108 away from 160, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
The number 54 fits into 520 9 times, leaving a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 851047.79629
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
340 divided by 54 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 851047.796296
Subtract 324 from 340 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.

Moving on to step 15:
When dividing 160 by 54, we get 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 851047.7962962
If we subtract 108 from 160, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 16:
The number 54 fits into 520 9 times, leaving a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 851047.79629629
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 851047.79629629, with a leftover of 3.4e-08.
