We're dividing 807673 by 57 
The aim is to understand the frequency of 57 in 807673.

Moving on to step 1:
If we divide 8 by 57, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 57

Advancing to step 2:
80 divided by 57 is 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 57 from 80, we get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 57

Advancing to step 3:
When dividing 237 by 57, we get 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 228 from 237 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 57

Step 4:
96 divided by 57 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
Subtract 57 from 96 to get 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 57

Advancing to step 5:
57 goes into 397 6 times with a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 1416.0
Subtract 342 from 397 to get 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 57

Moving on to step 6:
The number 57 fits into 553 9 times, leaving a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 14169.0
Deduct 513 from 553 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
57 goes into 400 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 14169.7
If we take 399 away from 400, we end up 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.

Step 8:
When dividing 10 by 57, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 14169.7
The remainder is 10 after subtracting 0 from 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:
When dividing 100 by 57, we get 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 14169.701
If we subtract 57 from 100, we 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:
430 divided by 57 is 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 14169.7017
Deduct 399 from 430 and we're left 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.

Let's proceed to step 11:
57 goes into 310 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 14169.70175
The remainder is 25 after subtracting 285 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
250 divided by 57 is 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 14169.701754
The remainder is 22 after subtracting 228 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
The number 57 fits into 220 3 times, leaving a remainder of 49.
The next digit of our result is 3. 
Result so far: 14169.7017543
Deduct 171 from 220 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 14:
57 can be fit into 490 8 times, resulting in a remainder of 34.
The next digit of our result is 8. 
Result so far: 14169.70175438
Subtracting 456 from 490 leaves us with 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 outcome is 14169.70175438, with a leftover of 3.4e-08.
