Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 602

Moving on to step 3:
602 goes into 155 0 times with a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 155, we end up with 155.
Fetch the next digit (7) from the dividend, attach it to 155 and continue: 1557 / 602

Step 4:
When dividing 1557 by 602, we get 2 with a remainder of 353.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1204 from 1557 to get 353.
Grab the next digit (3) from the dividend, add it to 353, then carry on: 3533 / 602

Step 5:
602 can be fit into 3533 5 times, resulting in a remainder of 523.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 3010 from 3533 and we're left with 523.
Append the next digit (8) from the dividend to 523 and continue with: 5238 / 602

Advancing to step 6:
The number 602 fits into 5238 8 times, leaving a remainder of 422.
Use 8 as the next digit of our solution. 
Result so far: 258.0
Deduct 4816 from 5238 and we're left with 422.
Append the next digit (8) from the dividend to 422 and continue with: 4228 / 602

On to step 7:
602 goes into 4228 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 2587.0
Deduct 4214 from 4228 and we're left with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 602

Advancing to step 8:
602 goes into 145 0 times with a remainder of 145.
Record the quotient 0 as the next digit in the result. 
Result so far: 25870.0
The remainder is 145 after subtracting 0 from 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 9:
602 can be fit into 1450 2 times, resulting in a remainder of 246.
The next digit of our result is 2. 
Result so far: 25870.2
Subtracting 1204 from 1450 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 10:
602 goes into 2460 4 times with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 25870.24
Deduct 2408 from 2460 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
When dividing 520 by 602, we get 0 with a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 25870.24
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 12:
If we divide 5200 by 602, we get 8 and a remainder of 384.
Write down 8 as next digit of the result. 
Result so far: 25870.2408
Subtracting 4816 from 5200 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 13:
602 goes into 3840 6 times with a remainder of 228.
The number 6 becomes the next digit in our result. 
Result so far: 25870.24086
Deduct 3612 from 3840 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 14:
When dividing 2280 by 602, we get 3 with a remainder of 474.
Use 3 as the next digit of our solution. 
Result so far: 25870.240863
If we take 1806 away from 2280, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 15:
When dividing 4740 by 602, we get 7 with a remainder of 526.
The next digit of our result is 7. 
Result so far: 25870.2408637
If we subtract 4214 from 4740, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 16:
If we divide 5260 by 602, we get 8 and a remainder of 444.
The next digit of our result is 8. 
Result so far: 25870.24086378
The remainder is 444 after subtracting 4816 from 5260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

After the division, we end up with 25870.24086378 and a remainder of 4.44e-07.
