We look at the division of 29635140 by 451 
The aim is to understand the frequency of 451 in 29635140.

Let's proceed to step 1:
451 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 451

Step 2:
29 divided by 451 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 451

Advancing to step 3:
296 divided by 451 is 0 with a remainder of 296.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 296 leaves us with 296.
Include the next digit (3) from the dividend after 296, then repeat: 2963 / 451

Advancing to step 4:
If we divide 2963 by 451, we get 6 and a remainder of 257.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 2706 from 2963, we get 257.
Grab the next digit (5) from the dividend, add it to 257, then carry on: 2575 / 451

Going ahead to step 5:
When dividing 2575 by 451, we get 5 with a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 2255 away from 2575, we end up with 320.
Take the next digit (1) from the dividend and append it to 320, then repeat: 3201 / 451

Moving on to step 6:
When dividing 3201 by 451, we get 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 657.0
Deduct 3157 from 3201 and we're left with 44.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 451

On to step 7:
The number 451 fits into 444 0 times, leaving a remainder of 444.
Put 0 as the next digit of the answer. 
Result so far: 6570.0
Deduct 0 from 444 and we're left with 444.
Grab the next digit (0) from the dividend, add it to 444, then carry on: 4440 / 451

Advancing to step 8:
4440 divided by 451 is 9 with a remainder of 381.
Use 9 as the next digit of our solution. 
Result so far: 65709.0
Subtracting 4059 from 4440 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Going ahead to step 9:
The number 451 fits into 3810 8 times, leaving a remainder of 202.
Put 8 as the next digit of the answer. 
Result so far: 65709.8
Subtracting 3608 from 3810 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 10:
2020 divided by 451 is 4 with a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 65709.84
Subtracting 1804 from 2020 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 11:
451 can be fit into 2160 4 times, resulting in a remainder of 356.
Use 4 as the next digit of our solution. 
Result so far: 65709.844
If we take 1804 away from 2160, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The final outcome is 65709.844, with a leftover of 0.0356.
