We're dividing 840333 by 57 
The aim is to understand the frequency of 57 in 840333.

Going ahead to step 1:
57 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 57

Advancing to step 2:
57 goes into 84 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 57 from 84 and we're left with 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 57

Going ahead to step 3:
57 can be fit into 270 4 times, resulting in a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 228 from 270 leaves us with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 57

Moving on to step 4:
The number 57 fits into 423 7 times, leaving a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 147.0
Subtract 399 from 423 to get 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 57

Let's proceed to step 5:
57 can be fit into 243 4 times, resulting in a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 1474.0
Subtract 228 from 243 to get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 57

On to step 6:
If we divide 153 by 57, we get 2 and a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 14742.0
The remainder is 39 after subtracting 114 from 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
When dividing 390 by 57, we get 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 14742.6
Subtracting 342 from 390 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
57 can be fit into 480 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 14742.68
If we take 456 away from 480, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 57, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 14742.684
Deduct 228 from 240 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
57 can be fit into 120 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 14742.6842
Subtract 114 from 120 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.

Step 11:
60 divided by 57 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 14742.68421
If we take 57 away from 60, we end up with 3.
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 12:
57 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 14742.68421
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
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: 14742.6842105
Subtract 285 from 300 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
The number 57 fits into 150 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 14742.68421052
Subtract 114 from 150 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 14742.68421052, with a leftover of 3.6e-08.
