2139010 divided by 580 
Our goal is to divide 2139010 by 580.

Moving on to step 1:
580 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 580

Advancing 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
Deduct 0 from 21 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 580

Going ahead to step 3:
213 divided by 580 is 0 with a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 213 to get 213.
Take the next digit (9) from the dividend and append it to 213, then repeat: 2139 / 580

Let's proceed to step 4:
If we divide 2139 by 580, we get 3 and a remainder of 399.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1740 away from 2139, we end up with 399.
Include the next digit (0) from the dividend after 399, then repeat: 3990 / 580

On to step 5:
When dividing 3990 by 580, we get 6 with a remainder of 510.
The next digit of our result is 6. 
Result so far: 36.0
If we subtract 3480 from 3990, we get 510.
Include the next digit (1) from the dividend after 510, then repeat: 5101 / 580

Advancing to step 6:
If we divide 5101 by 580, we get 8 and a remainder of 461.
Put 8 as the next digit of the answer. 
Result so far: 368.0
If we subtract 4640 from 5101, we get 461.
Grab the next digit (0) from the dividend, add it to 461, then carry on: 4610 / 580

On to step 7:
The number 580 fits into 4610 7 times, leaving a remainder of 550.
Use 7 as the next digit of our solution. 
Result so far: 3687.0
Deduct 4060 from 4610 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 8:
When dividing 5500 by 580, we get 9 with a remainder of 280.
The next digit of our result is 9. 
Result so far: 3687.9
If we subtract 5220 from 5500, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 9:
When dividing 2800 by 580, we get 4 with a remainder of 480.
Put 4 as the next digit of the answer. 
Result so far: 3687.94
If we subtract 2320 from 2800, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 10:
When dividing 4800 by 580, we get 8 with a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 3687.948
Subtract 4640 from 4800 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
The number 580 fits into 1600 2 times, leaving a remainder of 440.
Put 2 as the next digit of the answer. 
Result so far: 3687.9482
The remainder is 440 after subtracting 1160 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 12:
The number 580 fits into 4400 7 times, leaving a remainder of 340.
Record the quotient 7 as the next digit in the result. 
Result so far: 3687.94827
If we take 4060 away from 4400, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 13:
When dividing 3400 by 580, we get 5 with a remainder of 500.
The number 5 becomes the next digit in our result. 
Result so far: 3687.948275
If we take 2900 away from 3400, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 14:
580 can be fit into 5000 8 times, resulting in a remainder of 360.
Write down 8 as next digit of the result. 
Result so far: 3687.9482758
Subtract 4640 from 5000 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 15:
When dividing 3600 by 580, we get 6 with a remainder of 120.
The next digit of our result is 6. 
Result so far: 3687.94827586
Deduct 3480 from 3600 and we're left with 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 3687.94827586 and a remainder of 1.2e-07.
