We divide 105415 by 20
Our goal is to divide 105415 by 20.

Moving on to step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 20

Going ahead to step 2:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 20

Step 3:
20 can be fit into 105 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 100 away from 105, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 20

Let's proceed to step 4:
20 can be fit into 54 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we take 40 away from 54, we end up with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 20

Going ahead to step 5:
141 divided by 20 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 527.0
If we subtract 140 from 141, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 20

Step 6:
20 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 5270.0
Subtract 0 from 15 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 5270.7
Subtracting 140 from 150 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5270.75
Deduct 100 from 100 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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5270.75
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.

Advancing to step 10:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5270.75
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.

In conclusion, the division gives 5270.75 with a balance of 0.0.
