We look at the division of 726411 by 57 
The aim is to understand the frequency of 57 in 726411.

Moving on to step 1:
When dividing 7 by 57, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 57

Going ahead to step 2:
57 can be fit into 72 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 57 away from 72, we end up with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 57

Moving on to step 3:
When dividing 156 by 57, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 114 from 156 leaves us with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 57

Let's proceed to step 4:
If we divide 424 by 57, we get 7 and a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 127.0
If we take 399 away from 424, we end up with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 57

Going ahead to step 5:
When dividing 251 by 57, we get 4 with a remainder of 23.
The next digit of our result is 4. 
Result so far: 1274.0
The remainder is 23 after subtracting 228 from 251.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 57

Moving on to step 6:
57 goes into 231 4 times with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 12744.0
If we subtract 228 from 231, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 57, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 12744.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
57 goes into 300 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12744.05
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.

On to step 9:
57 can be fit into 150 2 times, resulting in a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 12744.052
Subtract 114 from 150 to get 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 10:
57 goes into 360 6 times with a remainder of 18.
The next digit of our result is 6. 
Result so far: 12744.0526
If we subtract 342 from 360, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
If we divide 180 by 57, we get 3 and a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 12744.05263
If we take 171 away from 180, we end up with 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 12:
57 goes into 90 1 times with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 12744.052631
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.

Going ahead to step 13:
If we divide 330 by 57, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 12744.0526315
Subtracting 285 from 330 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 14:
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: 12744.05263157
Deduct 399 from 450 and we're left 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.

Our division results in 12744.05263157 with a remaining 5.1e-08.
