40399042 divided by 237 
The aim is to understand the frequency of 237 in 40399042.

Advancing to step 1:
237 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 237

Let's proceed to step 2:
If we divide 40 by 237, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 237

Moving on to step 3:
237 can be fit into 403 1 times, resulting in a remainder of 166.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 237 from 403 and we're left with 166.
Grab the next digit (9) from the dividend, add it to 166, then carry on: 1669 / 237

Going ahead to step 4:
1669 divided by 237 is 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 10 after subtracting 1659 from 1669.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 237

Advancing to step 5:
When dividing 109 by 237, we get 0 with a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
If we subtract 0 from 109, we get 109.
Include the next digit (0) from the dividend after 109, then repeat: 1090 / 237

Step 6:
If we divide 1090 by 237, we get 4 and a remainder of 142.
Record the quotient 4 as the next digit in the result. 
Result so far: 1704.0
Subtracting 948 from 1090 leaves us with 142.
Bring next digit (4) of the dividend behind the 142 and repeat the process: 1424 / 237

On to step 7:
If we divide 1424 by 237, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 17046.0
If we take 1422 away from 1424, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 237

Let's proceed to step 8:
22 divided by 237 is 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 170460.0
If we take 0 away from 22, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
237 goes into 220 0 times with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 170460.0
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 10:
237 can be fit into 2200 9 times, resulting in a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 170460.09
The remainder is 67 after subtracting 2133 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 11:
237 goes into 670 2 times with a remainder of 196.
Record the quotient 2 as the next digit in the result. 
Result so far: 170460.092
Subtract 474 from 670 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 12:
When dividing 1960 by 237, we get 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 170460.0928
The remainder is 64 after subtracting 1896 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
237 goes into 640 2 times with a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 170460.09282
Deduct 474 from 640 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 14:
The number 237 fits into 1660 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 170460.092827
Subtract 1659 from 1660 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 15:
10 divided by 237 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 170460.092827
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 16:
100 divided by 237 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 170460.092827
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 170460.092827, and the remainder is 1e-07.
