We look at the division of 672807 by 57 
The aim is to understand the frequency of 57 in 672807.

Let's proceed to step 1:
The number 57 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 57

On to step 2:
The number 57 fits into 67 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 10 after subtracting 57 from 67.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 57

On to step 3:
The number 57 fits into 102 1 times, leaving a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 57 from 102 to get 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 57

Going ahead to step 4:
The number 57 fits into 458 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 118.0
The remainder is 2 after subtracting 456 from 458.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 57

Advancing to step 5:
If we divide 20 by 57, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1180.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 57

Advancing to step 6:
57 can be fit into 207 3 times, resulting in a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 11803.0
Subtract 171 from 207 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.

Going ahead to step 7:
57 can be fit into 360 6 times, resulting in a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 11803.6
Deduct 342 from 360 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
57 goes into 180 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 11803.63
Subtracting 171 from 180 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
57 goes into 90 1 times with a remainder of 33.
The next digit of our result is 1. 
Result so far: 11803.631
If we take 57 away from 90, we end up 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.

Going ahead to step 10:
When dividing 330 by 57, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 11803.6315
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.

Moving on to step 11:
The number 57 fits into 450 7 times, leaving a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 11803.63157
Deduct 399 from 450 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 12:
When dividing 510 by 57, we get 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 11803.631578
Subtracting 456 from 510 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
57 can be fit into 540 9 times, resulting in a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 11803.6315789
Deduct 513 from 540 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 14:
57 can be fit into 270 4 times, resulting in a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 11803.63157894
Subtract 228 from 270 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 11803.63157894 with a remainder of 4.2e-08.
