We're dividing 378997 by 10 
The aim is to understand the frequency of 10 in 378997.

Step 1:
10 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 10

Let's proceed to step 2:
10 can be fit into 37 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 7 after subtracting 30 from 37.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 10

Advancing to step 3:
If we divide 78 by 10, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
The remainder is 8 after subtracting 70 from 78.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 10

Let's proceed to step 4:
10 goes into 89 8 times with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 378.0
Deduct 80 from 89 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 10

Step 5:
10 goes into 99 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 3789.0
If we subtract 90 from 99, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 10

Step 6:
97 divided by 10 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 37899.0
The remainder is 7 after subtracting 90 from 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
10 goes into 70 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 37899.7
If we take 70 away from 70, 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.

Going ahead to step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37899.7
Subtracting 0 from 0 leaves us 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.

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: 37899.7
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.

Our division results in 37899.7 with a remaining 0.0.
