Let's divide 365980 by 57
The aim is to understand the frequency of 57 in 365980.

Advancing to step 1:
When dividing 3 by 57, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 57

Advancing to step 2:
The number 57 fits into 36 0 times, leaving a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 57

On to step 3:
57 can be fit into 365 6 times, resulting in a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 342 from 365 leaves us with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 57

Let's proceed to step 4:
If we divide 239 by 57, we get 4 and a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we subtract 228 from 239, we get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 57

Moving on to step 5:
When dividing 118 by 57, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 642.0
Subtracting 114 from 118 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 57

Let's proceed to step 6:
If we divide 40 by 57, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6420.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
The number 57 fits into 400 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 6420.7
Subtracting 399 from 400 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
57 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 6420.7
Subtracting 0 from 10 leaves us 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.

Let's proceed to step 9:
If we divide 100 by 57, we get 1 and a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 6420.701
Subtract 57 from 100 to get 43.
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:
57 goes into 430 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 6420.7017
Subtracting 399 from 430 leaves us 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.

Step 11:
When dividing 310 by 57, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6420.70175
Deduct 285 from 310 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead 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: 6420.701754
Subtract 228 from 250 to get 22.
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.
The next digit of our result is 3. 
Result so far: 6420.7017543
The remainder is 49 after subtracting 171 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 14:
490 divided by 57 is 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 6420.70175438
If we subtract 456 from 490, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 6420.70175438 with a remainder of 3.4e-08.
