Let's divide 80393892 by 456
The aim is to understand the frequency of 456 in 80393892.

Step 1:
The number 456 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 456

Advancing to step 2:
The number 456 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 456

Advancing to step 3:
If we divide 803 by 456, we get 1 and a remainder of 347.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 456 from 803, we get 347.
Grab the next digit (9) from the dividend, add it to 347, then carry on: 3479 / 456

On to step 4:
If we divide 3479 by 456, we get 7 and a remainder of 287.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 3192 from 3479 to get 287.
Fetch the next digit (3) from the dividend, attach it to 287 and continue: 2873 / 456

Moving on to step 5:
If we divide 2873 by 456, we get 6 and a remainder of 137.
Use 6 as the next digit of our solution. 
Result so far: 176.0
If we subtract 2736 from 2873, we get 137.
Fetch the next digit (8) from the dividend, attach it to 137 and continue: 1378 / 456

Going ahead to step 6:
When dividing 1378 by 456, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 1763.0
If we take 1368 away from 1378, we end up with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 456

Moving on to step 7:
The number 456 fits into 109 0 times, leaving a remainder of 109.
Record the quotient 0 as the next digit in the result. 
Result so far: 17630.0
Subtracting 0 from 109 leaves us with 109.
Fetch the next digit (2) from the dividend, attach it to 109 and continue: 1092 / 456

Advancing to step 8:
1092 divided by 456 is 2 with a remainder of 180.
Write down 2 as next digit of the result. 
Result so far: 176302.0
If we subtract 912 from 1092, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
456 goes into 1800 3 times with a remainder of 432.
Write down 3 as next digit of the result. 
Result so far: 176302.3
Subtract 1368 from 1800 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.

Moving on to step 10:
456 goes into 4320 9 times with a remainder of 216.
Record the quotient 9 as the next digit in the result. 
Result so far: 176302.39
Subtract 4104 from 4320 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 11:
If we divide 2160 by 456, we get 4 and a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 176302.394
Subtracting 1824 from 2160 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 12:
456 can be fit into 3360 7 times, resulting in a remainder of 168.
Record the quotient 7 as the next digit in the result. 
Result so far: 176302.3947
Subtracting 3192 from 3360 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 13:
When dividing 1680 by 456, we get 3 with a remainder of 312.
Use 3 as the next digit of our solution. 
Result so far: 176302.39473
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.

On to step 14:
The number 456 fits into 3120 6 times, leaving a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 176302.394736
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.

Moving on to step 15:
The number 456 fits into 3840 8 times, leaving a remainder of 192.
Record the quotient 8 as the next digit in the result. 
Result so far: 176302.3947368
Deduct 3648 from 3840 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 16:
If we divide 1920 by 456, we get 4 and a remainder of 96.
The next digit of our result is 4. 
Result so far: 176302.39473684
If we take 1824 away from 1920, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 176302.39473684, with a leftover of 9.6e-08.
