781919 divided by 10 
The aim is to understand the frequency of 10 in 781919.

Advancing to step 1:
7 divided by 10 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 10

Advancing to step 2:
The number 10 fits into 78 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 70 from 78 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 10

Moving on to step 3:
When dividing 81 by 10, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 78.0
Subtract 80 from 81 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 10

On to step 4:
19 divided by 10 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 781.0
Deduct 10 from 19 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 10

Moving on to step 5:
When dividing 91 by 10, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 7819.0
The remainder is 1 after subtracting 90 from 91.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 10

On to step 6:
10 can be fit into 19 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 78191.0
Subtract 10 from 19 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
When dividing 90 by 10, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 78191.9
The remainder is 0 after subtracting 90 from 90.
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:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 78191.9
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.

Going ahead to step 9:
0 divided by 10 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 78191.9
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.

The final result is 78191.9 with a remainder of 0.0.
