We're dividing 519103 by 37 
The aim is to understand the frequency of 37 in 519103.

Going ahead to step 1:
5 divided by 37 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 37

Moving on to step 2:
If we divide 51 by 37, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 37 from 51, we get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 37

On to step 3:
37 can be fit into 149 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 148 from 149 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 37

Going ahead to step 4:
11 divided by 37 is 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 140.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 37

Step 5:
When dividing 110 by 37, we get 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 1402.0
If we subtract 74 from 110, we get 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 37

Step 6:
363 divided by 37 is 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 14029.0
Subtract 333 from 363 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
If we divide 300 by 37, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 14029.8
If we subtract 296 from 300, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
40 divided by 37 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 14029.81
If we subtract 37 from 40, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
When dividing 30 by 37, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 14029.81
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
37 goes into 300 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 14029.8108
Subtract 296 from 300 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
37 can be fit into 40 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 14029.81081
If we subtract 37 from 40, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
The number 37 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 14029.81081
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
When dividing 300 by 37, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 14029.8108108
Subtracting 296 from 300 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
37 goes into 40 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 14029.81081081
If we take 37 away from 40, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 14029.81081081, and the remainder is 3e-09.
