660807 ÷ 57 
The aim is to understand the frequency of 57 in 660807.

Going ahead to step 1:
6 divided by 57 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 57

Advancing to step 2:
When dividing 66 by 57, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 57 away from 66, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 57

Going ahead to step 3:
90 divided by 57 is 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 33 after subtracting 57 from 90.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 57

Moving on to step 4:
57 can be fit into 338 5 times, resulting in a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
If we subtract 285 from 338, we get 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 57

Step 5:
57 can be fit into 530 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 1159.0
Deduct 513 from 530 and we're left with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 57

Moving on to step 6:
When dividing 177 by 57, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 11593.0
Subtract 171 from 177 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
The number 57 fits into 60 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 11593.1
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
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: 11593.1
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.

Going ahead to step 9:
If we divide 300 by 57, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 11593.105
Deduct 285 from 300 and we're left with 15.
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 10:
150 divided by 57 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 11593.1052
Subtracting 114 from 150 leaves us 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 11:
When dividing 360 by 57, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 11593.10526
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
The number 57 fits into 180 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 11593.105263
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.

Let's proceed to step 13:
When dividing 90 by 57, we get 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 11593.1052631
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.

Moving on to step 14:
57 can be fit into 330 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 11593.10526315
If we take 285 away from 330, we end up 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.

The quotient of the division is 11593.10526315, and the remainder is 4.5e-08.
