We look at the division of 3650 by 57 
The aim is to understand the frequency of 57 in 3650.

Let's proceed to step 1:
The number 57 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 57

Step 2:
The number 57 fits into 36 0 times, leaving a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 57

Step 3:
57 goes into 365 6 times with a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 342 from 365 and we're left with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 57

Advancing to step 4:
The number 57 fits into 230 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Deduct 228 from 230 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 5:
57 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 64.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 6:
If we divide 200 by 57, we get 3 and a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 64.03
The remainder is 29 after subtracting 171 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
If we divide 290 by 57, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 64.035
Subtract 285 from 290 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
The number 57 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 64.035
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
If we divide 500 by 57, we get 8 and a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 64.03508
The remainder is 44 after subtracting 456 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
440 divided by 57 is 7 with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 64.035087
Deduct 399 from 440 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 11:
410 divided by 57 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 64.0350877
Subtract 399 from 410 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 64.0350877 with a remainder of 1.1e-07.
