We're dividing 21441586 by 10 
The aim is to understand the frequency of 10 in 21441586.

On to step 1:
10 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 10

Going ahead to step 2:
10 goes into 21 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 20 from 21, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 10

Let's proceed to step 3:
10 can be fit into 14 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 10 from 14 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 10

Let's proceed to step 4:
44 divided by 10 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 214.0
Deduct 40 from 44 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 10

Step 5:
The number 10 fits into 41 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 2144.0
Subtract 40 from 41 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 10

Let's proceed to step 6:
10 can be fit into 15 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 21441.0
If we subtract 10 from 15, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 10

Moving on to step 7:
58 divided by 10 is 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 214415.0
If we take 50 away from 58, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 10

Step 8:
If we divide 86 by 10, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 2144158.0
Deduct 80 from 86 and we're left 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.

Going ahead to step 9:
60 divided by 10 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 2144158.6
Deduct 60 from 60 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.

Step 10:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2144158.6
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.

Step 11:
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: 2144158.6
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.

In conclusion, the division gives 2144158.6 with a balance of 0.0.
