54387889 divided by 456 
The aim is to understand the frequency of 456 in 54387889.

Advancing to step 1:
456 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 456

Moving on to step 2:
54 divided by 456 is 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 456

Step 3:
The number 456 fits into 543 1 times, leaving a remainder of 87.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 456 from 543 to get 87.
Fetch the next digit (8) from the dividend, attach it to 87 and continue: 878 / 456

Going ahead to step 4:
If we divide 878 by 456, we get 1 and a remainder of 422.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 456 from 878 to get 422.
Include the next digit (7) from the dividend after 422, then repeat: 4227 / 456

Step 5:
The number 456 fits into 4227 9 times, leaving a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
If we subtract 4104 from 4227, we get 123.
Take the next digit (8) from the dividend and append it to 123, then repeat: 1238 / 456

Going ahead to step 6:
When dividing 1238 by 456, we get 2 with a remainder of 326.
The number 2 becomes the next digit in our result. 
Result so far: 1192.0
The remainder is 326 after subtracting 912 from 1238.
Include the next digit (8) from the dividend after 326, then repeat: 3268 / 456

On to step 7:
3268 divided by 456 is 7 with a remainder of 76.
Record the quotient 7 as the next digit in the result. 
Result so far: 11927.0
If we take 3192 away from 3268, we end up with 76.
Include the next digit (9) from the dividend after 76, then repeat: 769 / 456

Going ahead to step 8:
The number 456 fits into 769 1 times, leaving a remainder of 313.
Put 1 as the next digit of the answer. 
Result so far: 119271.0
Subtract 456 from 769 to get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 9:
When dividing 3130 by 456, we get 6 with a remainder of 394.
Use 6 as the next digit of our solution. 
Result so far: 119271.6
If we subtract 2736 from 3130, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 10:
The number 456 fits into 3940 8 times, leaving a remainder of 292.
Record the quotient 8 as the next digit in the result. 
Result so far: 119271.68
Subtracting 3648 from 3940 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 11:
The number 456 fits into 2920 6 times, leaving a remainder of 184.
The next digit of our result is 6. 
Result so far: 119271.686
Subtracting 2736 from 2920 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 12:
456 can be fit into 1840 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 119271.6864
Deduct 1824 from 1840 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
160 divided by 456 is 0 with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 119271.6864
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
If we divide 1600 by 456, we get 3 and a remainder of 232.
Put 3 as the next digit of the answer. 
Result so far: 119271.686403
Subtract 1368 from 1600 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 15:
456 goes into 2320 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 119271.6864035
Deduct 2280 from 2320 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 16:
400 divided by 456 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 119271.6864035
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 119271.6864035, and the remainder is 4e-07.
