We divide 857900 by 10
The aim is to understand the frequency of 10 in 857900.

Let's proceed to step 1:
10 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 10

Advancing to step 2:
If we divide 85 by 10, we get 8 and a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 80 away from 85, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 10

Advancing to step 3:
When dividing 57 by 10, we get 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we take 50 away from 57, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 10

Going ahead to step 4:
The number 10 fits into 79 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 857.0
Deduct 70 from 79 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 10

Let's proceed to step 5:
90 divided by 10 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 8579.0
The remainder is 0 after subtracting 90 from 90.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 10

Let's proceed to step 6:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 85790.0
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.

Going ahead to step 7:
If we divide 0 by 10, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 85790.0
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.

On to 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: 85790.0
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.

After the division, we end up with 85790.0 and a remainder of 0.0.
