We look at the division of 753873 by 37 
The aim is to understand the frequency of 37 in 753873.

Moving on to step 1:
37 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 37

On to step 2:
If we divide 75 by 37, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 1 after subtracting 74 from 75.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 37

Step 3:
When dividing 13 by 37, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 37

Let's proceed to step 4:
37 can be fit into 138 3 times, resulting in a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
If we take 111 away from 138, we end up with 27.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 37

Moving on to step 5:
The number 37 fits into 277 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 2037.0
Subtract 259 from 277 to get 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 37

On to step 6:
37 can be fit into 183 4 times, resulting in a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 20374.0
If we subtract 148 from 183, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
350 divided by 37 is 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 20374.9
The remainder is 17 after subtracting 333 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
37 can be fit into 170 4 times, resulting in a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 20374.94
Deduct 148 from 170 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
If we divide 220 by 37, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 20374.945
Subtracting 185 from 220 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
The number 37 fits into 350 9 times, leaving a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 20374.9459
Subtracting 333 from 350 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 11:
The number 37 fits into 170 4 times, leaving a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 20374.94594
Subtract 148 from 170 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
220 divided by 37 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 20374.945945
The remainder is 35 after subtracting 185 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
When dividing 350 by 37, we get 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 20374.9459459
If we subtract 333 from 350, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
If we divide 170 by 37, we get 4 and a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 20374.94594594
If we take 148 away from 170, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 20374.94594594 with a balance of 2.2e-08.
