We look at the division of 622581 by 57 
The aim is to understand the frequency of 57 in 622581.

On to step 1:
57 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 57

Going ahead to step 2:
When dividing 62 by 57, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 57 from 62 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 57

Going ahead to step 3:
57 can be fit into 52 0 times, resulting in a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 52 leaves us with 52.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 57

Step 4:
The number 57 fits into 525 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 109.0
Deduct 513 from 525 and we're left with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 57

On to step 5:
The number 57 fits into 128 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1092.0
The remainder is 14 after subtracting 114 from 128.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 57

Step 6:
57 can be fit into 141 2 times, resulting in a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 10922.0
If we subtract 114 from 141, we get 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 7:
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: 10922.4
Deduct 228 from 270 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
57 can be fit into 420 7 times, resulting in a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 10922.47
If we take 399 away from 420, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
When dividing 210 by 57, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 10922.473
If we take 171 away from 210, we end up 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 10:
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: 10922.4736
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.

Going ahead to step 11:
The number 57 fits into 480 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 10922.47368
If we subtract 456 from 480, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
If we divide 240 by 57, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 10922.473684
Subtracting 228 from 240 leaves us 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 13:
If we divide 120 by 57, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 10922.4736842
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.

Let's proceed to step 14:
57 goes into 60 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 10922.47368421
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 10922.47368421, and the remainder is 3e-09.
