We're dividing 2535473 by 580 
We want to figure out the number of times 2535473 can be divided by 580.

On to step 1:
The number 580 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 580

On to step 2:
When dividing 25 by 580, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 580

Moving on to step 3:
When dividing 253 by 580, we get 0 with a remainder of 253.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 253 after subtracting 0 from 253.
Grab the next digit (5) from the dividend, add it to 253, then carry on: 2535 / 580

Advancing to step 4:
580 goes into 2535 4 times with a remainder of 215.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2320 from 2535, we get 215.
Include the next digit (4) from the dividend after 215, then repeat: 2154 / 580

Step 5:
580 can be fit into 2154 3 times, resulting in a remainder of 414.
Write down 3 as next digit of the result. 
Result so far: 43.0
Deduct 1740 from 2154 and we're left with 414.
Grab the next digit (7) from the dividend, add it to 414, then carry on: 4147 / 580

On to step 6:
580 goes into 4147 7 times with a remainder of 87.
The next digit of our result is 7. 
Result so far: 437.0
Deduct 4060 from 4147 and we're left with 87.
Grab the next digit (3) from the dividend, add it to 87, then carry on: 873 / 580

Going ahead to step 7:
When dividing 873 by 580, we get 1 with a remainder of 293.
The number 1 becomes the next digit in our result. 
Result so far: 4371.0
Subtracting 580 from 873 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 8:
580 goes into 2930 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 4371.5
If we subtract 2900 from 2930, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 580, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 4371.5
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 10:
580 goes into 3000 5 times with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 4371.505
The remainder is 100 after subtracting 2900 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
1000 divided by 580 is 1 with a remainder of 420.
Record the quotient 1 as the next digit in the result. 
Result so far: 4371.5051
Subtract 580 from 1000 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 12:
The number 580 fits into 4200 7 times, leaving a remainder of 140.
Write down 7 as next digit of the result. 
Result so far: 4371.50517
If we take 4060 away from 4200, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
If we divide 1400 by 580, we get 2 and a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 4371.505172
If we take 1160 away from 1400, we end up 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.

Going ahead to step 14:
580 can be fit into 2400 4 times, resulting in a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 4371.5051724
Subtracting 2320 from 2400 leaves us with 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 15:
580 goes into 800 1 times with a remainder of 220.
Record the quotient 1 as the next digit in the result. 
Result so far: 4371.50517241
Deduct 580 from 800 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 4371.50517241, with a leftover of 2.2e-07.
