We look at the division of 745086 by 10 
The aim is to understand the frequency of 10 in 745086.

Let's proceed to step 1:
When dividing 7 by 10, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 10

Step 2:
When dividing 74 by 10, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 70 from 74, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 10

Moving on to step 3:
If we divide 45 by 10, we get 4 and a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 74.0
The remainder is 5 after subtracting 40 from 45.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 10

Step 4:
50 divided by 10 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 745.0
Deduct 50 from 50 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 10

Advancing to step 5:
If we divide 8 by 10, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 7450.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 10

Moving on to step 6:
10 goes into 86 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 74508.0
If we take 80 away from 86, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
10 can be fit into 60 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 74508.6
The remainder is 0 after subtracting 60 from 60.
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:
0 divided by 10 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 74508.6
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.

Moving on to step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 74508.6
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.

The final outcome is 74508.6, with a leftover of 0.0.
