We look at the division of 20902607 by 480 
We want to divide 20902607 by 480.

Step 1:
480 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 480

Going ahead to step 2:
480 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 480

Moving on to step 3:
480 can be fit into 209 0 times, resulting in a remainder of 209.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 209, we end up with 209.
Fetch the next digit (0) from the dividend, attach it to 209 and continue: 2090 / 480

Advancing to step 4:
480 can be fit into 2090 4 times, resulting in a remainder of 170.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 170 after subtracting 1920 from 2090.
Grab the next digit (2) from the dividend, add it to 170, then carry on: 1702 / 480

Advancing to step 5:
1702 divided by 480 is 3 with a remainder of 262.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 1440 from 1702 leaves us with 262.
Grab the next digit (6) from the dividend, add it to 262, then carry on: 2626 / 480

Step 6:
The number 480 fits into 2626 5 times, leaving a remainder of 226.
Use 5 as the next digit of our solution. 
Result so far: 435.0
The remainder is 226 after subtracting 2400 from 2626.
Grab the next digit (0) from the dividend, add it to 226, then carry on: 2260 / 480

Moving on to step 7:
The number 480 fits into 2260 4 times, leaving a remainder of 340.
Write down 4 as next digit of the result. 
Result so far: 4354.0
The remainder is 340 after subtracting 1920 from 2260.
Append the next digit (7) from the dividend to 340 and continue with: 3407 / 480

Advancing to step 8:
480 can be fit into 3407 7 times, resulting in a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 43547.0
Deduct 3360 from 3407 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 9:
When dividing 470 by 480, we get 0 with a remainder of 470.
The next digit of our result is 0. 
Result so far: 43547.0
If we subtract 0 from 470, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 10:
The number 480 fits into 4700 9 times, leaving a remainder of 380.
The number 9 becomes the next digit in our result. 
Result so far: 43547.09
Subtracting 4320 from 4700 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 11:
When dividing 3800 by 480, we get 7 with a remainder of 440.
Record the quotient 7 as the next digit in the result. 
Result so far: 43547.097
If we take 3360 away from 3800, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 12:
4400 divided by 480 is 9 with a remainder of 80.
The number 9 becomes the next digit in our result. 
Result so far: 43547.0979
Subtract 4320 from 4400 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
When dividing 800 by 480, we get 1 with a remainder of 320.
Write down 1 as next digit of the result. 
Result so far: 43547.09791
Subtract 480 from 800 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 14:
480 can be fit into 3200 6 times, resulting in a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 43547.097916
The remainder is 320 after subtracting 2880 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 15:
480 can be fit into 3200 6 times, resulting in a remainder of 320.
Record the quotient 6 as the next digit in the result. 
Result so far: 43547.0979166
The remainder is 320 after subtracting 2880 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 43547.0979166 with a remaining 3.2e-06.
