We look at the division of 55283759 by 957 
The aim is to understand the frequency of 957 in 55283759.

Going ahead to step 1:
If we divide 5 by 957, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 957

On to step 2:
The number 957 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 957

Advancing to step 3:
957 goes into 552 0 times with a remainder of 552.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 552 after subtracting 0 from 552.
Append the next digit (8) from the dividend to 552 and continue with: 5528 / 957

Step 4:
When dividing 5528 by 957, we get 5 with a remainder of 743.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 743 after subtracting 4785 from 5528.
Grab the next digit (3) from the dividend, add it to 743, then carry on: 7433 / 957

Going ahead to step 5:
7433 divided by 957 is 7 with a remainder of 734.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtracting 6699 from 7433 leaves us with 734.
Take the next digit (7) from the dividend and append it to 734, then repeat: 7347 / 957

Let's proceed to step 6:
If we divide 7347 by 957, we get 7 and a remainder of 648.
Put 7 as the next digit of the answer. 
Result so far: 577.0
The remainder is 648 after subtracting 6699 from 7347.
Take the next digit (5) from the dividend and append it to 648, then repeat: 6485 / 957

On to step 7:
When dividing 6485 by 957, we get 6 with a remainder of 743.
The number 6 becomes the next digit in our result. 
Result so far: 5776.0
If we subtract 5742 from 6485, we get 743.
Append the next digit (9) from the dividend to 743 and continue with: 7439 / 957

Step 8:
When dividing 7439 by 957, we get 7 with a remainder of 740.
Record the quotient 7 as the next digit in the result. 
Result so far: 57767.0
Subtract 6699 from 7439 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 9:
7400 divided by 957 is 7 with a remainder of 701.
Record the quotient 7 as the next digit in the result. 
Result so far: 57767.7
Deduct 6699 from 7400 and we're left with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Step 10:
957 can be fit into 7010 7 times, resulting in a remainder of 311.
Write down 7 as next digit of the result. 
Result so far: 57767.77
If we subtract 6699 from 7010, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

The final result is 57767.77 with a remainder of 0.311.
