We look at the division of 35309147 by 456 
The aim is to understand the frequency of 456 in 35309147.

Advancing to step 1:
456 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 456

Step 2:
456 can be fit into 35 0 times, resulting in a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 456

Step 3:
353 divided by 456 is 0 with a remainder of 353.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 353 to get 353.
Take the next digit (0) from the dividend and append it to 353, then repeat: 3530 / 456

On to step 4:
456 can be fit into 3530 7 times, resulting in a remainder of 338.
The next digit of our result is 7. 
Result so far: 7.0
If we take 3192 away from 3530, we end up with 338.
Fetch the next digit (9) from the dividend, attach it to 338 and continue: 3389 / 456

Step 5:
456 can be fit into 3389 7 times, resulting in a remainder of 197.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Deduct 3192 from 3389 and we're left with 197.
Bring next digit (1) of the dividend behind the 197 and repeat the process: 1971 / 456

Let's proceed to step 6:
If we divide 1971 by 456, we get 4 and a remainder of 147.
The number 4 becomes the next digit in our result. 
Result so far: 774.0
Subtract 1824 from 1971 to get 147.
Include the next digit (4) from the dividend after 147, then repeat: 1474 / 456

Moving on to step 7:
The number 456 fits into 1474 3 times, leaving a remainder of 106.
Put 3 as the next digit of the answer. 
Result so far: 7743.0
The remainder is 106 after subtracting 1368 from 1474.
Bring next digit (7) of the dividend behind the 106 and repeat the process: 1067 / 456

Advancing to step 8:
456 can be fit into 1067 2 times, resulting in a remainder of 155.
Write down 2 as next digit of the result. 
Result so far: 77432.0
If we subtract 912 from 1067, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 9:
If we divide 1550 by 456, we get 3 and a remainder of 182.
Put 3 as the next digit of the answer. 
Result so far: 77432.3
Subtracting 1368 from 1550 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 10:
456 can be fit into 1820 3 times, resulting in a remainder of 452.
Write down 3 as next digit of the result. 
Result so far: 77432.33
Subtract 1368 from 1820 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

After the division, we end up with 77432.33 and a remainder of 0.452.
