Let's divide 37295739 by 15
The aim is to understand the frequency of 15 in 37295739.

Step 1:
The number 15 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 15

On to step 2:
If we divide 37 by 15, we get 2 and a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 7 after subtracting 30 from 37.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 15

Advancing to step 3:
The number 15 fits into 72 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 60 from 72 and we're left with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 15

Step 4:
When dividing 129 by 15, we get 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 248.0
If we take 120 away from 129, we end up with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 15

Advancing to step 5:
95 divided by 15 is 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 2486.0
If we take 90 away from 95, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 15

On to step 6:
15 goes into 57 3 times with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 24863.0
Subtract 45 from 57 to get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 15

Step 7:
When dividing 123 by 15, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 248638.0
Subtracting 120 from 123 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 15

On to step 8:
39 divided by 15 is 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2486382.0
If we subtract 30 from 39, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
15 goes into 90 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 2486382.6
Deduct 90 from 90 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2486382.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
15 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2486382.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 2486382.6, and the remainder is 0.0.
