549129 ÷ 37 
The aim is to understand the frequency of 37 in 549129.

On to step 1:
If we divide 5 by 37, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 37

On to step 2:
37 goes into 54 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 37 from 54, we get 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 37

Let's proceed to step 3:
When dividing 179 by 37, we get 4 with a remainder of 31.
The next digit of our result is 4. 
Result so far: 14.0
If we take 148 away from 179, we end up with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 37

On to step 4:
37 goes into 311 8 times with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 148.0
Subtracting 296 from 311 leaves us with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 37

Let's proceed to step 5:
If we divide 152 by 37, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 1484.0
The remainder is 4 after subtracting 148 from 152.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 37

Advancing to step 6:
49 divided by 37 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 14841.0
If we take 37 away from 49, we end up 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.

Let's proceed to step 7:
If we divide 120 by 37, we get 3 and a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 14841.3
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.

Advancing to step 8:
90 divided by 37 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 14841.32
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 9:
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: 14841.324
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 10:
37 can be fit into 120 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 14841.3243
If we take 111 away from 120, we end up 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.

On to step 11:
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: 14841.32432
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.

On to step 12:
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: 14841.324324
If we subtract 148 from 160, we 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.

Going ahead to step 13:
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: 14841.3243243
If we subtract 111 from 120, we 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.

Moving on to step 14:
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: 14841.32432432
The remainder is 16 after subtracting 74 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 14841.32432432, with a leftover of 1.6e-08.
