We look at the division of 843577 by 10 
The aim is to understand the frequency of 10 in 843577.

Step 1:
The number 10 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 10

Going ahead to step 2:
When dividing 84 by 10, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 80 from 84 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 10

Advancing to step 3:
The number 10 fits into 43 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we take 40 away from 43, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 10

Let's proceed to step 4:
If we divide 35 by 10, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 843.0
The remainder is 5 after subtracting 30 from 35.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 10

On to step 5:
10 can be fit into 57 5 times, resulting in a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 8435.0
Deduct 50 from 57 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 10

Advancing to step 6:
10 goes into 77 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 84357.0
If we take 70 away from 77, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
When dividing 70 by 10, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 84357.7
If we subtract 70 from 70, 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 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 84357.7
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.

Going ahead to step 9:
0 divided by 10 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 84357.7
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 84357.7 with a remaining 0.0.
