We look at the division of 736573 by 37 
The aim is to understand the frequency of 37 in 736573.

Moving on to step 1:
When dividing 7 by 37, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 37

On to step 2:
If we divide 73 by 37, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 36 after subtracting 37 from 73.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 37

Step 3:
37 can be fit into 366 9 times, resulting in a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 333 from 366 to get 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 37

Let's proceed to step 4:
If we divide 335 by 37, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 199.0
If we take 333 away from 335, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 37

On to step 5:
37 goes into 27 0 times with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 1990.0
Subtract 0 from 27 to get 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 37

Step 6:
37 goes into 273 7 times with a remainder of 14.
The next digit of our result is 7. 
Result so far: 19907.0
The remainder is 14 after subtracting 259 from 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
If we divide 140 by 37, we get 3 and a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 19907.3
Deduct 111 from 140 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 8:
When dividing 290 by 37, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 19907.37
If we take 259 away from 290, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
37 can be fit into 310 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 19907.378
Deduct 296 from 310 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
37 goes into 140 3 times with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 19907.3783
If we take 111 away from 140, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
37 can be fit into 290 7 times, resulting in a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 19907.37837
Subtracting 259 from 290 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
37 goes into 310 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 19907.378378
Deduct 296 from 310 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
If we divide 140 by 37, we get 3 and a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 19907.3783783
Subtract 111 from 140 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 14:
290 divided by 37 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 19907.37837837
Subtract 259 from 290 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 19907.37837837 with a remaining 3.1e-08.
