4671578 ÷ 457 
The aim is to understand the frequency of 457 in 4671578.

On to step 1:
The number 457 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 457

Moving on to step 2:
457 goes into 46 0 times with a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 46, we get 46.
Take the next digit (7) from the dividend and append it to 46, then repeat: 467 / 457

Advancing to step 3:
When dividing 467 by 457, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 457 from 467, we get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 457

Advancing to step 4:
The number 457 fits into 101 0 times, leaving a remainder of 101.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 101, we get 101.
Grab the next digit (5) from the dividend, add it to 101, then carry on: 1015 / 457

Going ahead to step 5:
If we divide 1015 by 457, we get 2 and a remainder of 101.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtract 914 from 1015 to get 101.
Fetch the next digit (7) from the dividend, attach it to 101 and continue: 1017 / 457

Going ahead to step 6:
If we divide 1017 by 457, we get 2 and a remainder of 103.
The number 2 becomes the next digit in our result. 
Result so far: 1022.0
Subtract 914 from 1017 to get 103.
Take the next digit (8) from the dividend and append it to 103, then repeat: 1038 / 457

Advancing to step 7:
If we divide 1038 by 457, we get 2 and a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 10222.0
The remainder is 124 after subtracting 914 from 1038.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 8:
When dividing 1240 by 457, we get 2 with a remainder of 326.
Write down 2 as next digit of the result. 
Result so far: 10222.2
Subtracting 914 from 1240 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 9:
457 can be fit into 3260 7 times, resulting in a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 10222.27
Subtract 3199 from 3260 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
When dividing 610 by 457, we get 1 with a remainder of 153.
Use 1 as the next digit of our solution. 
Result so far: 10222.271
Subtracting 457 from 610 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 11:
The number 457 fits into 1530 3 times, leaving a remainder of 159.
The next digit of our result is 3. 
Result so far: 10222.2713
The remainder is 159 after subtracting 1371 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 12:
When dividing 1590 by 457, we get 3 with a remainder of 219.
Record the quotient 3 as the next digit in the result. 
Result so far: 10222.27133
Subtracting 1371 from 1590 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

The final outcome is 10222.27133, with a leftover of 0.000219.
