We look at the division of 41870131 by 37 
The aim is to understand the frequency of 37 in 41870131.

Advancing to step 1:
When dividing 4 by 37, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 37

On to step 2:
If we divide 41 by 37, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 37 from 41 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 37

Going ahead to step 3:
The number 37 fits into 48 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 11 after subtracting 37 from 48.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 37

Moving on to step 4:
37 goes into 117 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 113.0
If we subtract 111 from 117, we get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 37

Let's proceed to step 5:
When dividing 60 by 37, we get 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1131.0
If we subtract 37 from 60, we get 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 37

Step 6:
If we divide 231 by 37, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 11316.0
Subtract 222 from 231 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 37

Let's proceed to step 7:
37 goes into 93 2 times with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 113162.0
Subtracting 74 from 93 leaves us with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 37

Step 8:
37 can be fit into 191 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 1131625.0
Subtract 185 from 191 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 9:
If we divide 60 by 37, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1131625.1
Deduct 37 from 60 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
37 can be fit into 230 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 1131625.16
The remainder is 8 after subtracting 222 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
37 goes into 80 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 1131625.162
Subtract 74 from 80 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.

Step 12:
If we divide 60 by 37, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1131625.1621
Subtract 37 from 60 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
37 can be fit into 230 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 1131625.16216
If we take 222 away from 230, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
37 goes into 80 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1131625.162162
The remainder is 6 after subtracting 74 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 15:
60 divided by 37 is 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1131625.1621621
Subtract 37 from 60 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 16:
If we divide 230 by 37, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 1131625.16216216
If we subtract 222 from 230, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 1131625.16216216 with a remaining 8e-09.
