We divide 762939 by 15
The aim is to understand the frequency of 15 in 762939.

Moving on to step 1:
If we divide 7 by 15, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 15

Going ahead to step 2:
When dividing 76 by 15, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 75 from 76 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 15

Advancing to step 3:
15 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 15

Advancing to step 4:
If we divide 129 by 15, we get 8 and a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 508.0
Subtract 120 from 129 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 15

Let's proceed to step 5:
93 divided by 15 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 5086.0
If we subtract 90 from 93, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 15

Advancing to step 6:
15 can be fit into 39 2 times, resulting in a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 50862.0
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.

Going ahead to step 7:
15 can be fit into 90 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 50862.6
Subtract 90 from 90 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50862.6
Deduct 0 from 0 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 9:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50862.6
Deduct 0 from 0 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.

The final result is 50862.6 with a remainder of 0.0.
