We're dividing 591917 by 57 
The aim is to understand the frequency of 57 in 591917.

Step 1:
When dividing 5 by 57, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 57

Let's proceed to step 2:
57 goes into 59 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 57 from 59, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 57

Moving on to step 3:
21 divided by 57 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 21, we get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 57

Going ahead to step 4:
57 goes into 219 3 times with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 103.0
Subtracting 171 from 219 leaves us with 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 57

Moving on to step 5:
If we divide 481 by 57, we get 8 and a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 1038.0
If we take 456 away from 481, we end up with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 57

Going ahead to step 6:
257 divided by 57 is 4 with a remainder of 29.
The next digit of our result is 4. 
Result so far: 10384.0
If we take 228 away from 257, we end up with 29.
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:
When dividing 290 by 57, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 10384.5
If we subtract 285 from 290, we 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.

Advancing to step 8:
When dividing 50 by 57, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10384.5
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
The number 57 fits into 500 8 times, leaving a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 10384.508
If we take 456 away from 500, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
The number 57 fits into 440 7 times, leaving a remainder of 41.
The next digit of our result is 7. 
Result so far: 10384.5087
The remainder is 41 after subtracting 399 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
57 goes into 410 7 times with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 10384.50877
If we take 399 away from 410, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 10384.50877 with a balance of 1.1e-05.
