We look at the division of 52142191 by 957 
The aim is to understand the frequency of 957 in 52142191.

Advancing to step 1:
957 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 957

Step 2:
957 goes into 52 0 times with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 957

Going ahead to step 3:
The number 957 fits into 521 0 times, leaving a remainder of 521.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 521 leaves us with 521.
Take the next digit (4) from the dividend and append it to 521, then repeat: 5214 / 957

Step 4:
The number 957 fits into 5214 5 times, leaving a remainder of 429.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4785 from 5214 and we're left with 429.
Append the next digit (2) from the dividend to 429 and continue with: 4292 / 957

Let's proceed to step 5:
957 goes into 4292 4 times with a remainder of 464.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we subtract 3828 from 4292, we get 464.
Append the next digit (1) from the dividend to 464 and continue with: 4641 / 957

Let's proceed to step 6:
The number 957 fits into 4641 4 times, leaving a remainder of 813.
The number 4 becomes the next digit in our result. 
Result so far: 544.0
If we subtract 3828 from 4641, we get 813.
Fetch the next digit (9) from the dividend, attach it to 813 and continue: 8139 / 957

On to step 7:
If we divide 8139 by 957, we get 8 and a remainder of 483.
Write down 8 as next digit of the result. 
Result so far: 5448.0
Subtracting 7656 from 8139 leaves us with 483.
Append the next digit (1) from the dividend to 483 and continue with: 4831 / 957

Let's proceed to step 8:
957 can be fit into 4831 5 times, resulting in a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 54485.0
Subtract 4785 from 4831 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
The number 957 fits into 460 0 times, leaving a remainder of 460.
The number 0 becomes the next digit in our result. 
Result so far: 54485.0
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 10:
When dividing 4600 by 957, we get 4 with a remainder of 772.
The next digit of our result is 4. 
Result so far: 54485.04
Deduct 3828 from 4600 and we're left with 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Going ahead to step 11:
The number 957 fits into 7720 8 times, leaving a remainder of 64.
The next digit of our result is 8. 
Result so far: 54485.048
Deduct 7656 from 7720 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
If we divide 640 by 957, we get 0 and a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 54485.048
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 13:
The number 957 fits into 6400 6 times, leaving a remainder of 658.
Record the quotient 6 as the next digit in the result. 
Result so far: 54485.04806
If we subtract 5742 from 6400, we get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

On to step 14:
957 can be fit into 6580 6 times, resulting in a remainder of 838.
Put 6 as the next digit of the answer. 
Result so far: 54485.048066
The remainder is 838 after subtracting 5742 from 6580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

In conclusion, the division gives 54485.048066 with a balance of 8.38e-05.
