365125 ÷ 57 
The aim is to understand the frequency of 57 in 365125.

On to step 1:
If we divide 3 by 57, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 57

Step 2:
57 goes into 36 0 times with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 57

Step 3:
The number 57 fits into 365 6 times, leaving a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 342 away from 365, we end up with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 57

Let's proceed to step 4:
57 goes into 231 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 228 from 231 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 57

Advancing to step 5:
If we divide 32 by 57, we get 0 and a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 640.0
Subtracting 0 from 32 leaves us with 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 57

Going ahead to step 6:
If we divide 325 by 57, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 6405.0
The remainder is 40 after subtracting 285 from 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
If we divide 400 by 57, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 6405.7
Subtract 399 from 400 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
10 divided by 57 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 6405.7
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 57, we get 1 with a remainder of 43.
The next digit of our result is 1. 
Result so far: 6405.701
The remainder is 43 after subtracting 57 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 10:
The number 57 fits into 430 7 times, leaving a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 6405.7017
If we take 399 away from 430, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
When dividing 310 by 57, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 6405.70175
The remainder is 25 after subtracting 285 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
When dividing 250 by 57, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 6405.701754
The remainder is 22 after subtracting 228 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
57 can be fit into 220 3 times, resulting in a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 6405.7017543
Deduct 171 from 220 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 14:
57 goes into 490 8 times with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 6405.70175438
The remainder is 34 after subtracting 456 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The quotient of the division is 6405.70175438, and the remainder is 3.4e-08.
