42372009 ÷ 957 
The aim is to understand the frequency of 957 in 42372009.

Moving on to step 1:
If we divide 4 by 957, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 957

Moving on to step 2:
42 divided by 957 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 957

Let's proceed to step 3:
If we divide 423 by 957, we get 0 and a remainder of 423.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 423, we end up with 423.
Take the next digit (7) from the dividend and append it to 423, then repeat: 4237 / 957

Advancing to step 4:
957 goes into 4237 4 times with a remainder of 409.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3828 away from 4237, we end up with 409.
Fetch the next digit (2) from the dividend, attach it to 409 and continue: 4092 / 957

Moving on to step 5:
957 goes into 4092 4 times with a remainder of 264.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 3828 from 4092 leaves us with 264.
Include the next digit (0) from the dividend after 264, then repeat: 2640 / 957

On to step 6:
2640 divided by 957 is 2 with a remainder of 726.
The number 2 becomes the next digit in our result. 
Result so far: 442.0
If we take 1914 away from 2640, we end up with 726.
Grab the next digit (0) from the dividend, add it to 726, then carry on: 7260 / 957

Advancing to step 7:
If we divide 7260 by 957, we get 7 and a remainder of 561.
Use 7 as the next digit of our solution. 
Result so far: 4427.0
Subtracting 6699 from 7260 leaves us with 561.
Fetch the next digit (9) from the dividend, attach it to 561 and continue: 5619 / 957

Step 8:
957 can be fit into 5619 5 times, resulting in a remainder of 834.
Use 5 as the next digit of our solution. 
Result so far: 44275.0
If we subtract 4785 from 5619, we get 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Moving on to step 9:
If we divide 8340 by 957, we get 8 and a remainder of 684.
Record the quotient 8 as the next digit in the result. 
Result so far: 44275.8
The remainder is 684 after subtracting 7656 from 8340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 10:
957 goes into 6840 7 times with a remainder of 141.
Use 7 as the next digit of our solution. 
Result so far: 44275.87
If we take 6699 away from 6840, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 11:
957 goes into 1410 1 times with a remainder of 453.
Write down 1 as next digit of the result. 
Result so far: 44275.871
If we take 957 away from 1410, we end up with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Going ahead to step 12:
4530 divided by 957 is 4 with a remainder of 702.
The number 4 becomes the next digit in our result. 
Result so far: 44275.8714
If we take 3828 away from 4530, we end up with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Step 13:
957 can be fit into 7020 7 times, resulting in a remainder of 321.
Use 7 as the next digit of our solution. 
Result so far: 44275.87147
The remainder is 321 after subtracting 6699 from 7020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 14:
The number 957 fits into 3210 3 times, leaving a remainder of 339.
The next digit of our result is 3. 
Result so far: 44275.871473
Deduct 2871 from 3210 and we're left with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 15:
957 goes into 3390 3 times with a remainder of 519.
Use 3 as the next digit of our solution. 
Result so far: 44275.8714733
The remainder is 519 after subtracting 2871 from 3390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

The final result is 44275.8714733 with a remainder of 5.19e-06.
