375435 divided by 57 
The aim is to understand the frequency of 57 in 375435.

Moving on to step 1:
The number 57 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 57

Moving on to step 2:
57 can be fit into 37 0 times, resulting in a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 57

Going ahead to step 3:
57 can be fit into 375 6 times, resulting in a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 33 after subtracting 342 from 375.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 57

Let's proceed to step 4:
The number 57 fits into 334 5 times, leaving a remainder of 49.
The next digit of our result is 5. 
Result so far: 65.0
Subtract 285 from 334 to get 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 57

Advancing to step 5:
When dividing 493 by 57, we get 8 with a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 658.0
Subtract 456 from 493 to get 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 57

Advancing to step 6:
When dividing 375 by 57, we get 6 with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 6586.0
Deduct 342 from 375 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.

On to step 7:
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: 6586.5
Deduct 285 from 330 and we're left 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.

On to step 8:
When dividing 450 by 57, we get 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 6586.57
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.

Let's proceed to step 9:
When dividing 510 by 57, we get 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 6586.578
Deduct 456 from 510 and we're left 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.

Moving on to step 10:
540 divided by 57 is 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 6586.5789
Subtracting 513 from 540 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
57 can be fit into 270 4 times, resulting in a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 6586.57894
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
When dividing 420 by 57, we get 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 6586.578947
If we take 399 away from 420, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 13:
If we divide 210 by 57, we get 3 and a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 6586.5789473
Deduct 171 from 210 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 14:
57 goes into 390 6 times with a remainder of 48.
The next digit of our result is 6. 
Result so far: 6586.57894736
The remainder is 48 after subtracting 342 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 6586.57894736 and a remainder of 4.8e-08.
