We look at the division of 747522 by 57 
The aim is to understand the frequency of 57 in 747522.

On to step 1:
7 divided by 57 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 57

Going ahead to step 2:
If we divide 74 by 57, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 57 from 74, we get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 57

Step 3:
57 can be fit into 177 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 171 from 177 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 57

Going ahead to step 4:
65 divided by 57 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 131.0
Subtracting 57 from 65 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 57

Going ahead to step 5:
82 divided by 57 is 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1311.0
If we take 57 away from 82, we end up with 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 57

Step 6:
57 can be fit into 252 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 13114.0
The remainder is 24 after subtracting 228 from 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
If we divide 240 by 57, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 13114.4
The remainder is 12 after subtracting 228 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 57 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 13114.42
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 57, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 13114.421
Subtracting 57 from 60 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
The number 57 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 13114.421
Subtract 0 from 30 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.

Advancing to step 11:
The number 57 fits into 300 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 13114.42105
If we subtract 285 from 300, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
57 goes into 150 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 13114.421052
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.

On to step 13:
When dividing 360 by 57, we get 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 13114.4210526
If we take 342 away from 360, we end up 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.

Advancing to step 14:
57 goes into 180 3 times with a remainder of 9.
The next digit of our result is 3. 
Result so far: 13114.42105263
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.

The final outcome is 13114.42105263, with a leftover of 9e-09.
