We look at the division of 515772 by 10 
The aim is to understand the frequency of 10 in 515772.

Moving on to step 1:
When dividing 5 by 10, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 10

Step 2:
When dividing 51 by 10, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 50 from 51 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 10

Advancing to step 3:
10 goes into 15 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtract 10 from 15 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 10

On to step 4:
When dividing 57 by 10, we get 5 with a remainder of 7.
The next digit of our result is 5. 
Result so far: 515.0
Deduct 50 from 57 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 10

Step 5:
When dividing 77 by 10, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 5157.0
If we take 70 away from 77, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 10

Let's proceed to step 6:
The number 10 fits into 72 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 51577.0
Deduct 70 from 72 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 10, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 51577.2
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 10 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 51577.2
If we subtract 0 from 0, we 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 9:
0 divided by 10 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 51577.2
Subtract 0 from 0 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.

The final result is 51577.2 with a remainder of 0.0.
