We're dividing 722951 by 37 
The aim is to understand the frequency of 37 in 722951.

Advancing to step 1:
The number 37 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 37

On to step 2:
When dividing 72 by 37, we get 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 37 from 72 and we're left with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 37

Step 3:
352 divided by 37 is 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 19 after subtracting 333 from 352.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 37

Going ahead to step 4:
When dividing 199 by 37, we get 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
The remainder is 14 after subtracting 185 from 199.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 37

Advancing to step 5:
37 goes into 145 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 1953.0
Subtracting 111 from 145 leaves us with 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 37

Moving on to step 6:
341 divided by 37 is 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 19539.0
Deduct 333 from 341 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
80 divided by 37 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 19539.2
The remainder is 6 after subtracting 74 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
60 divided by 37 is 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 19539.21
If we take 37 away from 60, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
If we divide 230 by 37, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 19539.216
If we take 222 away from 230, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 37 fits into 80 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 19539.2162
The remainder is 6 after subtracting 74 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
When dividing 60 by 37, we get 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 19539.21621
If we subtract 37 from 60, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 12:
230 divided by 37 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 19539.216216
If we take 222 away from 230, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
The number 37 fits into 80 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 19539.2162162
The remainder is 6 after subtracting 74 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
37 goes into 60 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 19539.21621621
Deduct 37 from 60 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 19539.21621621 with a remainder of 2.3e-08.
