437804 divided by 37 
The aim is to understand the frequency of 37 in 437804.

Moving on to step 1:
When dividing 4 by 37, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 37

Going ahead to step 2:
37 goes into 43 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 37 from 43 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 37

Moving on to step 3:
37 can be fit into 67 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 37 from 67, we get 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 37

Advancing to step 4:
37 can be fit into 308 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 118.0
Deduct 296 from 308 and we're left with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 37

Moving on to step 5:
37 can be fit into 120 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 1183.0
Deduct 111 from 120 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 37

Step 6:
94 divided by 37 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 11832.0
If we subtract 74 from 94, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
The number 37 fits into 200 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 11832.5
Subtracting 185 from 200 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
When dividing 150 by 37, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 11832.54
If we subtract 148 from 150, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
If we divide 20 by 37, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 11832.54
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 37 fits into 200 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 11832.5405
Subtract 185 from 200 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
37 can be fit into 150 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 11832.54054
If we subtract 148 from 150, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
The number 37 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11832.54054
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
200 divided by 37 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 11832.5405405
Deduct 185 from 200 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
When dividing 150 by 37, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 11832.54054054
The remainder is 2 after subtracting 148 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 11832.54054054, with a leftover of 2e-09.
