We look at the division of 25850804 by 602 
Let's see how many times 602 fits into 25850804.

Advancing to step 1:
2 divided by 602 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 602

Let's proceed to step 2:
The number 602 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 602

Advancing to step 3:
The number 602 fits into 258 0 times, leaving a remainder of 258.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 258 after subtracting 0 from 258.
Grab the next digit (5) from the dividend, add it to 258, then carry on: 2585 / 602

Going ahead to step 4:
2585 divided by 602 is 4 with a remainder of 177.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 2408 from 2585, we get 177.
Fetch the next digit (0) from the dividend, attach it to 177 and continue: 1770 / 602

On to step 5:
602 goes into 1770 2 times with a remainder of 566.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 1204 from 1770 leaves us with 566.
Grab the next digit (8) from the dividend, add it to 566, then carry on: 5668 / 602

Moving on to step 6:
The number 602 fits into 5668 9 times, leaving a remainder of 250.
The number 9 becomes the next digit in our result. 
Result so far: 429.0
Deduct 5418 from 5668 and we're left with 250.
Fetch the next digit (0) from the dividend, attach it to 250 and continue: 2500 / 602

Advancing to step 7:
602 can be fit into 2500 4 times, resulting in a remainder of 92.
Put 4 as the next digit of the answer. 
Result so far: 4294.0
The remainder is 92 after subtracting 2408 from 2500.
Grab the next digit (4) from the dividend, add it to 92, then carry on: 924 / 602

Moving on to step 8:
The number 602 fits into 924 1 times, leaving a remainder of 322.
The number 1 becomes the next digit in our result. 
Result so far: 42941.0
The remainder is 322 after subtracting 602 from 924.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 9:
602 goes into 3220 5 times with a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 42941.5
The remainder is 210 after subtracting 3010 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
2100 divided by 602 is 3 with a remainder of 294.
Use 3 as the next digit of our solution. 
Result so far: 42941.53
The remainder is 294 after subtracting 1806 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 11:
2940 divided by 602 is 4 with a remainder of 532.
Put 4 as the next digit of the answer. 
Result so far: 42941.534
If we subtract 2408 from 2940, we get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 12:
If we divide 5320 by 602, we get 8 and a remainder of 504.
Record the quotient 8 as the next digit in the result. 
Result so far: 42941.5348
Subtract 4816 from 5320 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 13:
When dividing 5040 by 602, we get 8 with a remainder of 224.
Use 8 as the next digit of our solution. 
Result so far: 42941.53488
Subtracting 4816 from 5040 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

After the division, we end up with 42941.53488 and a remainder of 0.000224.
