739648 ÷ 37 
The aim is to understand the frequency of 37 in 739648.

Let's proceed to step 1:
If we divide 7 by 37, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 37

Step 2:
37 can be fit into 73 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 37 away from 73, we end up with 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 37

On to step 3:
37 can be fit into 369 9 times, resulting in a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 333 from 369, we get 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 37

Advancing to step 4:
The number 37 fits into 366 9 times, leaving a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 199.0
If we take 333 away from 366, we end up with 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 37

On to step 5:
37 can be fit into 334 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1999.0
Subtracting 333 from 334 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 37

On to step 6:
If we divide 18 by 37, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 19990.0
The remainder is 18 after subtracting 0 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
If we divide 180 by 37, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 19990.4
If we take 148 away from 180, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
When dividing 320 by 37, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 19990.48
Subtracting 296 from 320 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
37 goes into 240 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 19990.486
Subtracting 222 from 240 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
37 goes into 180 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 19990.4864
Deduct 148 from 180 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
320 divided by 37 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 19990.48648
If we take 296 away from 320, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
37 can be fit into 240 6 times, resulting in a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 19990.486486
Subtract 222 from 240 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
37 can be fit into 180 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 19990.4864864
Subtract 148 from 180 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
If we divide 320 by 37, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 19990.48648648
If we subtract 296 from 320, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 19990.48648648 with a remainder of 2.4e-08.
