We look at the division of 52161416 by 457 
The aim is to understand the frequency of 457 in 52161416.

Let's proceed to step 1:
When dividing 5 by 457, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 457

Let's proceed to step 2:
If we divide 52 by 457, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 457

On to step 3:
When dividing 521 by 457, we get 1 with a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 457 from 521 and we're left with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 457

Moving on to step 4:
The number 457 fits into 646 1 times, leaving a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 457 from 646 leaves us with 189.
Fetch the next digit (1) from the dividend, attach it to 189 and continue: 1891 / 457

Let's proceed to step 5:
When dividing 1891 by 457, we get 4 with a remainder of 63.
Write down 4 as next digit of the result. 
Result so far: 114.0
The remainder is 63 after subtracting 1828 from 1891.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 457

Going ahead to step 6:
The number 457 fits into 634 1 times, leaving a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 1141.0
Subtract 457 from 634 to get 177.
Grab the next digit (1) from the dividend, add it to 177, then carry on: 1771 / 457

Advancing to step 7:
The number 457 fits into 1771 3 times, leaving a remainder of 400.
The next digit of our result is 3. 
Result so far: 11413.0
If we subtract 1371 from 1771, we get 400.
Grab the next digit (6) from the dividend, add it to 400, then carry on: 4006 / 457

Going ahead to step 8:
If we divide 4006 by 457, we get 8 and a remainder of 350.
Put 8 as the next digit of the answer. 
Result so far: 114138.0
The remainder is 350 after subtracting 3656 from 4006.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 9:
457 can be fit into 3500 7 times, resulting in a remainder of 301.
Put 7 as the next digit of the answer. 
Result so far: 114138.7
Subtracting 3199 from 3500 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 10:
457 can be fit into 3010 6 times, resulting in a remainder of 268.
The next digit of our result is 6. 
Result so far: 114138.76
Subtracting 2742 from 3010 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 11:
2680 divided by 457 is 5 with a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 114138.765
The remainder is 395 after subtracting 2285 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Let's proceed to step 12:
The number 457 fits into 3950 8 times, leaving a remainder of 294.
Put 8 as the next digit of the answer. 
Result so far: 114138.7658
Subtract 3656 from 3950 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 13:
457 goes into 2940 6 times with a remainder of 198.
The number 6 becomes the next digit in our result. 
Result so far: 114138.76586
Subtract 2742 from 2940 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 14:
1980 divided by 457 is 4 with a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 114138.765864
Subtracting 1828 from 1980 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 15:
The number 457 fits into 1520 3 times, leaving a remainder of 149.
Use 3 as the next digit of our solution. 
Result so far: 114138.7658643
The remainder is 149 after subtracting 1371 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 16:
1490 divided by 457 is 3 with a remainder of 119.
Use 3 as the next digit of our solution. 
Result so far: 114138.76586433
The remainder is 119 after subtracting 1371 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

The final outcome is 114138.76586433, with a leftover of 1.19e-07.
