We look at the division of 40670354 by 305 
The aim is to understand the frequency of 305 in 40670354.

Moving on to step 1:
If we divide 4 by 305, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 305

On to step 2:
If we divide 40 by 305, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 305

Let's proceed to step 3:
305 can be fit into 406 1 times, resulting in a remainder of 101.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 101 after subtracting 305 from 406.
Bring next digit (7) of the dividend behind the 101 and repeat the process: 1017 / 305

Advancing to step 4:
If we divide 1017 by 305, we get 3 and a remainder of 102.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 915 from 1017 and we're left with 102.
Grab the next digit (0) from the dividend, add it to 102, then carry on: 1020 / 305

Advancing to step 5:
305 goes into 1020 3 times with a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
If we subtract 915 from 1020, we get 105.
Grab the next digit (3) from the dividend, add it to 105, then carry on: 1053 / 305

On to step 6:
The number 305 fits into 1053 3 times, leaving a remainder of 138.
Write down 3 as next digit of the result. 
Result so far: 1333.0
Subtracting 915 from 1053 leaves us with 138.
Bring next digit (5) of the dividend behind the 138 and repeat the process: 1385 / 305

Going ahead to step 7:
The number 305 fits into 1385 4 times, leaving a remainder of 165.
Use 4 as the next digit of our solution. 
Result so far: 13334.0
Deduct 1220 from 1385 and we're left with 165.
Take the next digit (4) from the dividend and append it to 165, then repeat: 1654 / 305

On to step 8:
305 goes into 1654 5 times with a remainder of 129.
The number 5 becomes the next digit in our result. 
Result so far: 133345.0
Deduct 1525 from 1654 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 9:
1290 divided by 305 is 4 with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 133345.4
Subtracting 1220 from 1290 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
305 goes into 700 2 times with a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 133345.42
Subtracting 610 from 700 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
The number 305 fits into 900 2 times, leaving a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 133345.422
The remainder is 290 after subtracting 610 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The quotient of the division is 133345.422, and the remainder is 0.029.
