We look at the division of 417533 by 57 
The aim is to understand the frequency of 57 in 417533.

Advancing to step 1:
57 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 57

Moving on to step 2:
57 goes into 41 0 times with a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 57

Step 3:
When dividing 417 by 57, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 18 after subtracting 399 from 417.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 57

On to step 4:
When dividing 185 by 57, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Deduct 171 from 185 and we're left with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 57

Let's proceed to step 5:
If we divide 143 by 57, we get 2 and a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 732.0
Subtracting 114 from 143 leaves us with 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 57

On to step 6:
The number 57 fits into 293 5 times, leaving a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 7325.0
If we subtract 285 from 293, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
57 can be fit into 80 1 times, resulting in a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 7325.1
Subtract 57 from 80 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 8:
230 divided by 57 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 7325.14
The remainder is 2 after subtracting 228 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
20 divided by 57 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 7325.14
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 57 fits into 200 3 times, leaving a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 7325.1403
Subtracting 171 from 200 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
57 can be fit into 290 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7325.14035
Subtract 285 from 290 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
If we divide 50 by 57, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 7325.14035
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
500 divided by 57 is 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 7325.1403508
Subtracting 456 from 500 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
440 divided by 57 is 7 with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 7325.14035087
If we subtract 399 from 440, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 7325.14035087, with a leftover of 4.1e-08.
