21651045 divided by 480 
We want to figure out the number of times 21651045 can be divided by 480.

Advancing to step 1:
The number 480 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 480

Let's proceed to step 2:
480 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 480

Let's proceed to step 3:
480 can be fit into 216 0 times, resulting in a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 216 after subtracting 0 from 216.
Append the next digit (5) from the dividend to 216 and continue with: 2165 / 480

Step 4:
2165 divided by 480 is 4 with a remainder of 245.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 1920 from 2165 to get 245.
Take the next digit (1) from the dividend and append it to 245, then repeat: 2451 / 480

On to step 5:
When dividing 2451 by 480, we get 5 with a remainder of 51.
The next digit of our result is 5. 
Result so far: 45.0
If we take 2400 away from 2451, we end up with 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 480

Advancing to step 6:
The number 480 fits into 510 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 451.0
Subtract 480 from 510 to get 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 480

Let's proceed to step 7:
If we divide 304 by 480, we get 0 and a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 4510.0
If we subtract 0 from 304, we get 304.
Grab the next digit (5) from the dividend, add it to 304, then carry on: 3045 / 480

Moving on to step 8:
480 can be fit into 3045 6 times, resulting in a remainder of 165.
Put 6 as the next digit of the answer. 
Result so far: 45106.0
Deduct 2880 from 3045 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 9:
480 can be fit into 1650 3 times, resulting in a remainder of 210.
Record the quotient 3 as the next digit in the result. 
Result so far: 45106.3
Subtract 1440 from 1650 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
When dividing 2100 by 480, we get 4 with a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 45106.34
If we subtract 1920 from 2100, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
When dividing 1800 by 480, we get 3 with a remainder of 360.
Record the quotient 3 as the next digit in the result. 
Result so far: 45106.343
Deduct 1440 from 1800 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 12:
3600 divided by 480 is 7 with a remainder of 240.
Use 7 as the next digit of our solution. 
Result so far: 45106.3437
Deduct 3360 from 3600 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
If we divide 2400 by 480, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 45106.34375
If we subtract 2400 from 2400, 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.

Advancing to step 14:
480 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 45106.34375
If we take 0 away from 0, we end up 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.

Moving on to step 15:
480 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45106.34375
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 45106.34375 with a remainder of 0.0.
