We look at the division of 28580524 by 402 
Let's see how many times 402 fits into 28580524.

Going ahead to step 1:
2 divided by 402 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 402

Advancing to step 2:
The number 402 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 402

Advancing to step 3:
The number 402 fits into 285 0 times, leaving a remainder of 285.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 285, we end up with 285.
Bring next digit (8) of the dividend behind the 285 and repeat the process: 2858 / 402

On to step 4:
If we divide 2858 by 402, we get 7 and a remainder of 44.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 2814 from 2858 to get 44.
Append the next digit (0) from the dividend to 44 and continue with: 440 / 402

Advancing to step 5:
If we divide 440 by 402, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we subtract 402 from 440, we get 38.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 402

Moving on to step 6:
402 goes into 385 0 times with a remainder of 385.
Put 0 as the next digit of the answer. 
Result so far: 710.0
Subtract 0 from 385 to get 385.
Take the next digit (2) from the dividend and append it to 385, then repeat: 3852 / 402

Let's proceed to step 7:
402 can be fit into 3852 9 times, resulting in a remainder of 234.
The number 9 becomes the next digit in our result. 
Result so far: 7109.0
If we take 3618 away from 3852, we end up with 234.
Take the next digit (4) from the dividend and append it to 234, then repeat: 2344 / 402

Let's proceed to step 8:
If we divide 2344 by 402, we get 5 and a remainder of 334.
Put 5 as the next digit of the answer. 
Result so far: 71095.0
The remainder is 334 after subtracting 2010 from 2344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 9:
402 can be fit into 3340 8 times, resulting in a remainder of 124.
Write down 8 as next digit of the result. 
Result so far: 71095.8
Deduct 3216 from 3340 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 10:
When dividing 1240 by 402, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 71095.83
Subtracting 1206 from 1240 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
The number 402 fits into 340 0 times, leaving a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 71095.83
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 12:
402 goes into 3400 8 times with a remainder of 184.
Put 8 as the next digit of the answer. 
Result so far: 71095.8308
Deduct 3216 from 3400 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 13:
When dividing 1840 by 402, we get 4 with a remainder of 232.
Write down 4 as next digit of the result. 
Result so far: 71095.83084
Subtract 1608 from 1840 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 14:
The number 402 fits into 2320 5 times, leaving a remainder of 310.
Write down 5 as next digit of the result. 
Result so far: 71095.830845
The remainder is 310 after subtracting 2010 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 15:
The number 402 fits into 3100 7 times, leaving a remainder of 286.
Use 7 as the next digit of our solution. 
Result so far: 71095.8308457
Subtracting 2814 from 3100 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 16:
When dividing 2860 by 402, we get 7 with a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 71095.83084577
Deduct 2814 from 2860 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 71095.83084577, with a leftover of 4.6e-08.
