We're dividing 626811 by 57 
The aim is to understand the frequency of 57 in 626811.

Advancing to step 1:
If we divide 6 by 57, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 57

Going ahead to step 2:
57 can be fit into 62 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 57 from 62, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 57

On to step 3:
If we divide 56 by 57, we get 0 and a remainder of 56.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 56 after subtracting 0 from 56.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 57

Going ahead to step 4:
If we divide 568 by 57, we get 9 and a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we subtract 513 from 568, we get 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 57

On to step 5:
If we divide 551 by 57, we get 9 and a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 1099.0
Subtract 513 from 551 to get 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 57

Advancing to step 6:
When dividing 381 by 57, we get 6 with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 10996.0
Deduct 342 from 381 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
57 goes into 390 6 times with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 10996.6
If we subtract 342 from 390, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
If we divide 480 by 57, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 10996.68
The remainder is 24 after subtracting 456 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
If we divide 240 by 57, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 10996.684
If we subtract 228 from 240, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 57, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 10996.6842
Subtracting 114 from 120 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
The number 57 fits into 60 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 10996.68421
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.

Going ahead to step 12:
When dividing 30 by 57, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10996.68421
If we take 0 away from 30, we end up with 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 13:
When dividing 300 by 57, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 10996.6842105
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.

On to step 14:
If we divide 150 by 57, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 10996.68421052
If we subtract 114 from 150, we 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.

After the division, we end up with 10996.68421052 and a remainder of 3.6e-08.
