We look at the division of 762435 by 57 
The aim is to understand the frequency of 57 in 762435.

Step 1:
The number 57 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 57

Step 2:
When dividing 76 by 57, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 57 from 76 leaves us with 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 57

Step 3:
57 goes into 192 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 171 from 192 leaves us with 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 57

Going ahead to step 4:
57 can be fit into 214 3 times, resulting in a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
The remainder is 43 after subtracting 171 from 214.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 57

Advancing to step 5:
433 divided by 57 is 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 1337.0
If we subtract 399 from 433, we get 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 57

Let's proceed to step 6:
If we divide 345 by 57, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 13376.0
If we subtract 342 from 345, 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.

Moving on to step 7:
When dividing 30 by 57, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 13376.0
If we subtract 0 from 30, we 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.

Step 8:
57 goes into 300 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 13376.05
The remainder is 15 after subtracting 285 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
57 can be fit into 150 2 times, resulting in a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 13376.052
If we take 114 away from 150, we end up 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 10:
57 can be fit into 360 6 times, resulting in a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 13376.0526
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.

Advancing to step 11:
180 divided by 57 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 13376.05263
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.

Moving on to step 12:
The number 57 fits into 90 1 times, leaving a remainder of 33.
The next digit of our result is 1. 
Result so far: 13376.052631
Deduct 57 from 90 and we're left 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:
When dividing 330 by 57, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 13376.0526315
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.

Moving on to step 14:
57 can be fit into 450 7 times, resulting in a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 13376.05263157
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.

After the division, we end up with 13376.05263157 and a remainder of 5.1e-08.
