We divide 715437 by 57
The aim is to understand the frequency of 57 in 715437.

Step 1:
The number 57 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 57

Let's proceed to step 2:
57 can be fit into 71 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 14 after subtracting 57 from 71.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 57

Let's proceed to step 3:
57 can be fit into 145 2 times, resulting in a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 114 from 145, we get 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 57

Going ahead to step 4:
If we divide 314 by 57, we get 5 and a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Subtracting 285 from 314 leaves us with 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 57

Step 5:
When dividing 293 by 57, we get 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 1255.0
If we take 285 away from 293, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 57

On to step 6:
57 can be fit into 87 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 12551.0
Subtract 57 from 87 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
When dividing 300 by 57, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12551.5
Subtracting 285 from 300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
57 goes into 150 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 12551.52
Subtracting 114 from 150 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
When dividing 360 by 57, we get 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 12551.526
Subtracting 342 from 360 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
57 can be fit into 180 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 12551.5263
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
If we divide 90 by 57, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 12551.52631
If we take 57 away from 90, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 12:
57 goes into 330 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 12551.526315
If we subtract 285 from 330, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
If we divide 450 by 57, we get 7 and a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 12551.5263157
If we take 399 away from 450, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 14:
57 can be fit into 510 8 times, resulting in a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 12551.52631578
Subtracting 456 from 510 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 12551.52631578 with a remainder of 5.4e-08.
