30351647 ÷ 451 
The aim is to understand the frequency of 451 in 30351647.

Going ahead to step 1:
451 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 451

On to step 2:
The number 451 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 451

Let's proceed to step 3:
The number 451 fits into 303 0 times, leaving a remainder of 303.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 303 and we're left with 303.
Bring next digit (5) of the dividend behind the 303 and repeat the process: 3035 / 451

Let's proceed to step 4:
451 goes into 3035 6 times with a remainder of 329.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 2706 from 3035 to get 329.
Bring next digit (1) of the dividend behind the 329 and repeat the process: 3291 / 451

Let's proceed to step 5:
451 can be fit into 3291 7 times, resulting in a remainder of 134.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Deduct 3157 from 3291 and we're left with 134.
Append the next digit (6) from the dividend to 134 and continue with: 1346 / 451

Let's proceed to step 6:
If we divide 1346 by 451, we get 2 and a remainder of 444.
The number 2 becomes the next digit in our result. 
Result so far: 672.0
If we take 902 away from 1346, we end up with 444.
Append the next digit (4) from the dividend to 444 and continue with: 4444 / 451

Going ahead to step 7:
4444 divided by 451 is 9 with a remainder of 385.
Put 9 as the next digit of the answer. 
Result so far: 6729.0
Subtract 4059 from 4444 to get 385.
Include the next digit (7) from the dividend after 385, then repeat: 3857 / 451

Advancing to step 8:
451 goes into 3857 8 times with a remainder of 249.
The next digit of our result is 8. 
Result so far: 67298.0
If we take 3608 away from 3857, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 9:
If we divide 2490 by 451, we get 5 and a remainder of 235.
Write down 5 as next digit of the result. 
Result so far: 67298.5
Deduct 2255 from 2490 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 10:
451 can be fit into 2350 5 times, resulting in a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 67298.55
Subtracting 2255 from 2350 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

After the division, we end up with 67298.55 and a remainder of 0.095.
