528647 ÷ 37 
The aim is to understand the frequency of 37 in 528647.

Going ahead to step 1:
When dividing 5 by 37, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 37

Advancing to step 2:
37 can be fit into 52 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 37 from 52 leaves us with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 37

Moving on to step 3:
37 goes into 158 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 148 from 158, we get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 37

Let's proceed to step 4:
106 divided by 37 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 142.0
Deduct 74 from 106 and we're left with 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 37

Advancing to step 5:
324 divided by 37 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 1428.0
Subtract 296 from 324 to get 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 37

Moving on to step 6:
287 divided by 37 is 7 with a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 14287.0
The remainder is 28 after subtracting 259 from 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
When dividing 280 by 37, we get 7 with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 14287.7
Subtracting 259 from 280 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
37 can be fit into 210 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 14287.75
If we subtract 185 from 210, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
37 goes into 250 6 times with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 14287.756
Subtracting 222 from 250 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
37 can be fit into 280 7 times, resulting in a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 14287.7567
The remainder is 21 after subtracting 259 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
37 can be fit into 210 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 14287.75675
The remainder is 25 after subtracting 185 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
The number 37 fits into 250 6 times, leaving a remainder of 28.
The next digit of our result is 6. 
Result so far: 14287.756756
Deduct 222 from 250 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
280 divided by 37 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 14287.7567567
If we take 259 away from 280, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
The number 37 fits into 210 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 14287.75675675
Subtracting 185 from 210 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 14287.75675675 and a remainder of 2.5e-08.
