66131352 divided by 456 
The aim is to understand the frequency of 456 in 66131352.

Moving on to step 1:
456 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 456

Let's proceed to step 2:
456 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 456

Step 3:
The number 456 fits into 661 1 times, leaving a remainder of 205.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 456 away from 661, we end up with 205.
Append the next digit (3) from the dividend to 205 and continue with: 2053 / 456

Step 4:
If we divide 2053 by 456, we get 4 and a remainder of 229.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 1824 from 2053 to get 229.
Grab the next digit (1) from the dividend, add it to 229, then carry on: 2291 / 456

On to step 5:
2291 divided by 456 is 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 145.0
The remainder is 11 after subtracting 2280 from 2291.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 456

Let's proceed to step 6:
113 divided by 456 is 0 with a remainder of 113.
The next digit of our result is 0. 
Result so far: 1450.0
Subtracting 0 from 113 leaves us with 113.
Include the next digit (5) from the dividend after 113, then repeat: 1135 / 456

On to step 7:
The number 456 fits into 1135 2 times, leaving a remainder of 223.
Use 2 as the next digit of our solution. 
Result so far: 14502.0
Subtract 912 from 1135 to get 223.
Take the next digit (2) from the dividend and append it to 223, then repeat: 2232 / 456

Let's proceed to step 8:
456 goes into 2232 4 times with a remainder of 408.
Put 4 as the next digit of the answer. 
Result so far: 145024.0
Deduct 1824 from 2232 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 9:
The number 456 fits into 4080 8 times, leaving a remainder of 432.
Write down 8 as next digit of the result. 
Result so far: 145024.8
Subtract 3648 from 4080 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 10:
456 can be fit into 4320 9 times, resulting in a remainder of 216.
The next digit of our result is 9. 
Result so far: 145024.89
The remainder is 216 after subtracting 4104 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 11:
2160 divided by 456 is 4 with a remainder of 336.
The next digit of our result is 4. 
Result so far: 145024.894
The remainder is 336 after subtracting 1824 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 12:
The number 456 fits into 3360 7 times, leaving a remainder of 168.
The next digit of our result is 7. 
Result so far: 145024.8947
Subtract 3192 from 3360 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 13:
1680 divided by 456 is 3 with a remainder of 312.
Write down 3 as next digit of the result. 
Result so far: 145024.89473
Deduct 1368 from 1680 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 14:
The number 456 fits into 3120 6 times, leaving a remainder of 384.
Put 6 as the next digit of the answer. 
Result so far: 145024.894736
Subtract 2736 from 3120 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 15:
The number 456 fits into 3840 8 times, leaving a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 145024.8947368
Subtract 3648 from 3840 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 16:
The number 456 fits into 1920 4 times, leaving a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 145024.89473684
If we subtract 1824 from 1920, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 145024.89473684 and a remainder of 9.6e-08.
