55755929 ÷ 451 
The aim is to understand the frequency of 451 in 55755929.

Let's proceed to step 1:
451 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 451

Step 2:
451 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 451

On to step 3:
557 divided by 451 is 1 with a remainder of 106.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 451 from 557, we get 106.
Append the next digit (5) from the dividend to 106 and continue with: 1065 / 451

Going ahead to step 4:
When dividing 1065 by 451, we get 2 with a remainder of 163.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 902 away from 1065, we end up with 163.
Take the next digit (5) from the dividend and append it to 163, then repeat: 1635 / 451

Let's proceed to step 5:
451 can be fit into 1635 3 times, resulting in a remainder of 282.
Put 3 as the next digit of the answer. 
Result so far: 123.0
If we subtract 1353 from 1635, we get 282.
Append the next digit (9) from the dividend to 282 and continue with: 2829 / 451

Let's proceed to step 6:
When dividing 2829 by 451, we get 6 with a remainder of 123.
The next digit of our result is 6. 
Result so far: 1236.0
Subtract 2706 from 2829 to get 123.
Include the next digit (2) from the dividend after 123, then repeat: 1232 / 451

Step 7:
The number 451 fits into 1232 2 times, leaving a remainder of 330.
Put 2 as the next digit of the answer. 
Result so far: 12362.0
Subtracting 902 from 1232 leaves us with 330.
Grab the next digit (9) from the dividend, add it to 330, then carry on: 3309 / 451

Step 8:
451 goes into 3309 7 times with a remainder of 152.
The next digit of our result is 7. 
Result so far: 123627.0
Subtracting 3157 from 3309 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 9:
If we divide 1520 by 451, we get 3 and a remainder of 167.
The next digit of our result is 3. 
Result so far: 123627.3
Subtract 1353 from 1520 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Let's proceed to step 10:
451 goes into 1670 3 times with a remainder of 317.
The number 3 becomes the next digit in our result. 
Result so far: 123627.33
Deduct 1353 from 1670 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

After the division, we end up with 123627.33 and a remainder of 0.317.
