725515 divided by 37 
The aim is to understand the frequency of 37 in 725515.

Going ahead to step 1:
37 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 37

Moving on to step 2:
When dividing 72 by 37, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 35 after subtracting 37 from 72.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 37

Going ahead to step 3:
355 divided by 37 is 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 333 from 355 and we're left with 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 37

On to step 4:
37 goes into 225 6 times with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 196.0
If we take 222 away from 225, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 37

Advancing to step 5:
37 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 1960.0
Subtract 0 from 31 to get 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 37

Let's proceed to step 6:
37 goes into 315 8 times with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 19608.0

37 goes into 190 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 19608.5
The remainder is 5 after subtracting 185 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 37, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 19608.51
Deduct 37 from 50 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
37 goes into 130 3 times with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 19608.513
Subtracting 111 from 130 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
When dividing 190 by 37, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 19608.5135
Deduct 185 from 190 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
If we divide 50 by 37, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 19608.51351
Subtracting 37 from 50 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
If we divide 130 by 37, we get 3 and a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 19608.513513
Subtract 111 from 130 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
190 divided by 37 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 19608.5135135
Subtracting 185 from 190 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
If we divide 50 by 37, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 19608.51351351
Subtracting 37 from 50 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.
