Let's divide 21026910 by 465
We want to divide 21026910 by 465.

Step 1:
465 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 465

Step 2:
The number 465 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 465

Let's proceed to step 3:
465 goes into 210 0 times with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 210 after subtracting 0 from 210.
Include the next digit (2) from the dividend after 210, then repeat: 2102 / 465

Moving on to step 4:
When dividing 2102 by 465, we get 4 with a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 1860 from 2102 to get 242.
Append the next digit (6) from the dividend to 242 and continue with: 2426 / 465

Step 5:
If we divide 2426 by 465, we get 5 and a remainder of 101.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we subtract 2325 from 2426, we get 101.
Append the next digit (9) from the dividend to 101 and continue with: 1019 / 465

Going ahead to step 6:
465 goes into 1019 2 times with a remainder of 89.
The next digit of our result is 2. 
Result so far: 452.0
Deduct 930 from 1019 and we're left with 89.
Fetch the next digit (1) from the dividend, attach it to 89 and continue: 891 / 465

Moving on to step 7:
465 can be fit into 891 1 times, resulting in a remainder of 426.
The number 1 becomes the next digit in our result. 
Result so far: 4521.0
Subtracting 465 from 891 leaves us with 426.
Bring next digit (0) of the dividend behind the 426 and repeat the process: 4260 / 465

Going ahead to step 8:
4260 divided by 465 is 9 with a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 45219.0
Subtracting 4185 from 4260 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
If we divide 750 by 465, we get 1 and a remainder of 285.
Write down 1 as next digit of the result. 
Result so far: 45219.1
Deduct 465 from 750 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 10:
If we divide 2850 by 465, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 45219.16
Subtract 2790 from 2850 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
465 goes into 600 1 times with a remainder of 135.
The next digit of our result is 1. 
Result so far: 45219.161
If we take 465 away from 600, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 12:
If we divide 1350 by 465, we get 2 and a remainder of 420.
The next digit of our result is 2. 
Result so far: 45219.1612
Subtract 930 from 1350 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 13:
The number 465 fits into 4200 9 times, leaving a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 45219.16129
Subtract 4185 from 4200 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.

On to step 14:
The number 465 fits into 150 0 times, leaving a remainder of 150.
The next digit of our result is 0. 
Result so far: 45219.16129
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 15:
The number 465 fits into 1500 3 times, leaving a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 45219.1612903
If we subtract 1395 from 1500, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 16:
When dividing 1050 by 465, we get 2 with a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 45219.16129032
Subtract 930 from 1050 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 45219.16129032 and a remainder of 1.2e-07.
