We're dividing 515731 by 10 
The aim is to understand the frequency of 10 in 515731.

Let's proceed to step 1:
10 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 10

On to step 2:
51 divided by 10 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 50 from 51, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 10

Step 3:
When dividing 15 by 10, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtracting 10 from 15 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 10

Let's proceed to step 4:
10 can be fit into 57 5 times, resulting in a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 515.0
Subtracting 50 from 57 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 10

Let's proceed to step 5:
If we divide 73 by 10, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 5157.0
If we subtract 70 from 73, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 10

On to step 6:
10 can be fit into 31 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 51573.0
Subtracting 30 from 31 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 10, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 51573.1
If we take 10 away from 10, 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.

Let's proceed to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 51573.1
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.

Advancing to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 51573.1
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.

Our division results in 51573.1 with a remaining 0.0.
