Let's divide 98569769 by 451
The aim is to understand the frequency of 451 in 98569769.

Advancing to step 1:
451 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 451

Advancing to step 2:
If we divide 98 by 451, we get 0 and a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 451

On to step 3:
The number 451 fits into 985 2 times, leaving a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 902 from 985 and we're left with 83.
Include the next digit (6) from the dividend after 83, then repeat: 836 / 451

Step 4:
451 goes into 836 1 times with a remainder of 385.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 451 from 836 to get 385.
Include the next digit (9) from the dividend after 385, then repeat: 3859 / 451

Step 5:
451 goes into 3859 8 times with a remainder of 251.
The next digit of our result is 8. 
Result so far: 218.0
Deduct 3608 from 3859 and we're left with 251.
Take the next digit (7) from the dividend and append it to 251, then repeat: 2517 / 451

Moving on to step 6:
451 goes into 2517 5 times with a remainder of 262.
Use 5 as the next digit of our solution. 
Result so far: 2185.0
Subtracting 2255 from 2517 leaves us with 262.
Fetch the next digit (6) from the dividend, attach it to 262 and continue: 2626 / 451

Advancing to step 7:
451 can be fit into 2626 5 times, resulting in a remainder of 371.
The number 5 becomes the next digit in our result. 
Result so far: 21855.0
Subtracting 2255 from 2626 leaves us with 371.
Fetch the next digit (9) from the dividend, attach it to 371 and continue: 3719 / 451

On to step 8:
451 goes into 3719 8 times with a remainder of 111.
Record the quotient 8 as the next digit in the result. 
Result so far: 218558.0
If we take 3608 away from 3719, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 9:
The number 451 fits into 1110 2 times, leaving a remainder of 208.
The next digit of our result is 2. 
Result so far: 218558.2
Subtracting 902 from 1110 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 10:
451 goes into 2080 4 times with a remainder of 276.
Write down 4 as next digit of the result. 
Result so far: 218558.24
Subtract 1804 from 2080 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 11:
The number 451 fits into 2760 6 times, leaving a remainder of 54.
The next digit of our result is 6. 
Result so far: 218558.246
Subtracting 2706 from 2760 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 12:
When dividing 540 by 451, we get 1 with a remainder of 89.
The next digit of our result is 1. 
Result so far: 218558.2461
If we take 451 away from 540, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 13:
If we divide 890 by 451, we get 1 and a remainder of 439.
The next digit of our result is 1. 
Result so far: 218558.24611
Subtract 451 from 890 to get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

The final outcome is 218558.24611, with a leftover of 0.000439.
