We're dividing 603412 by 37 
The aim is to understand the frequency of 37 in 603412.

Going ahead to step 1:
6 divided by 37 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 37

Let's proceed to step 2:
The number 37 fits into 60 1 times, leaving a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 37 from 60 to get 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 37

Moving on to step 3:
233 divided by 37 is 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 222 from 233 leaves us with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 37

Let's proceed to step 4:
114 divided by 37 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 163.0
Deduct 111 from 114 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 37

On to step 5:
When dividing 31 by 37, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 1630.0
If we take 0 away from 31, we end up with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 37

Going ahead to step 6:
37 goes into 312 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 16308.0
Subtract 296 from 312 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
When dividing 160 by 37, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 16308.4
Deduct 148 from 160 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
37 can be fit into 120 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 16308.43
Subtracting 111 from 120 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
The number 37 fits into 90 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 16308.432
If we subtract 74 from 90, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 37, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 16308.4324
The remainder is 12 after subtracting 148 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
When dividing 120 by 37, we get 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 16308.43243
Subtracting 111 from 120 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
If we divide 90 by 37, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 16308.432432
Subtract 74 from 90 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
37 can be fit into 160 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 16308.4324324
Subtract 148 from 160 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
37 goes into 120 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 16308.43243243
Subtract 111 from 120 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 16308.43243243, with a leftover of 9e-09.
