We're dividing 21479477 by 580 
Let's see how many times 580 fits into 21479477.

Going ahead to step 1:
The number 580 fits into 2 0 times, leaving 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 580

Moving on to step 2:
580 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 580

Advancing to step 3:
214 divided by 580 is 0 with a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 214, we end up with 214.
Append the next digit (7) from the dividend to 214 and continue with: 2147 / 580

Step 4:
2147 divided by 580 is 3 with a remainder of 407.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1740 from 2147, we get 407.
Append the next digit (9) from the dividend to 407 and continue with: 4079 / 580

Let's proceed to step 5:
The number 580 fits into 4079 7 times, leaving a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtracting 4060 from 4079 leaves us with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 580

On to step 6:
580 can be fit into 194 0 times, resulting in a remainder of 194.
Record the quotient 0 as the next digit in the result. 
Result so far: 370.0
Subtracting 0 from 194 leaves us with 194.
Grab the next digit (7) from the dividend, add it to 194, then carry on: 1947 / 580

Going ahead to step 7:
580 can be fit into 1947 3 times, resulting in a remainder of 207.
The next digit of our result is 3. 
Result so far: 3703.0
If we subtract 1740 from 1947, we get 207.
Bring next digit (7) of the dividend behind the 207 and repeat the process: 2077 / 580

On to step 8:
The number 580 fits into 2077 3 times, leaving a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 37033.0
If we subtract 1740 from 2077, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Advancing to step 9:
The number 580 fits into 3370 5 times, leaving a remainder of 470.
The next digit of our result is 5. 
Result so far: 37033.5
Deduct 2900 from 3370 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 10:
The number 580 fits into 4700 8 times, leaving a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 37033.58
Subtract 4640 from 4700 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.

Moving on to step 11:
If we divide 600 by 580, we get 1 and a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 37033.581
If we subtract 580 from 600, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
If we divide 200 by 580, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 37033.581
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
When dividing 2000 by 580, we get 3 with a remainder of 260.
The number 3 becomes the next digit in our result. 
Result so far: 37033.58103
If we subtract 1740 from 2000, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 14:
580 can be fit into 2600 4 times, resulting in a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 37033.581034
Deduct 2320 from 2600 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 15:
If we divide 2800 by 580, we get 4 and a remainder of 480.
Write down 4 as next digit of the result. 
Result so far: 37033.5810344
Deduct 2320 from 2800 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Our division results in 37033.5810344 with a remaining 4.8e-06.
