When dividing 8 by 602, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 602

On to step 2:
The number 602 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.

Fetch the next digit (3) from the dividend, attach it to 217 and continue: 2173 / 602

On to step 4:
The number 602 fits into 2173 3 times, leaving a remainder of 367.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 1806 from 2173 to get 367.
Take the next digit (4) from the dividend and append it to 367, then repeat: 3674 / 602

Advancing to step 5:
When dividing 3674 by 602, we get 6 with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 136.0
Subtract 3612 from 3674 to get 62.
Take the next digit (6) from the dividend and append it to 62, then repeat: 626 / 602

Going ahead to step 6:
When dividing 626 by 602, we get 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 1361.0
Deduct 602 from 626 and we're left with 24.
Take the next digit (6) from the dividend and append it to 24, then repeat: 246 / 602

Going ahead to step 7:
The number 602 fits into 246 0 times, leaving a remainder of 246.
Use 0 as the next digit of our solution. 
Result so far: 13610.0
If we subtract 0 from 246, we get 246.
Append the next digit (4) from the dividend to 246 and continue with: 2464 / 602

On to step 8:
602 goes into 2464 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 136104.0
Subtract 2408 from 2464 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
If we divide 560 by 602, we get 0 and a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 136104.0
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 10:
602 goes into 5600 9 times with a remainder of 182.
Record the quotient 9 as the next digit in the result. 
Result so far: 136104.09
If we subtract 5418 from 5600, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 11:
The number 602 fits into 1820 3 times, leaving a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 136104.093
Subtracting 1806 from 1820 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
602 can be fit into 140 0 times, resulting in a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 136104.093
If we take 0 away from 140, 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.

Advancing to step 13:
602 goes into 1400 2 times with a remainder of 196.
The number 2 becomes the next digit in our result. 
Result so far: 136104.09302
Deduct 1204 from 1400 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 14:
When dividing 1960 by 602, we get 3 with a remainder of 154.
The next digit of our result is 3. 
Result so far: 136104.093023
The remainder is 154 after subtracting 1806 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 15:
The number 602 fits into 1540 2 times, leaving a remainder of 336.
The next digit of our result is 2. 
Result so far: 136104.0930232
If we subtract 1204 from 1540, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 16:
3360 divided by 602 is 5 with a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 136104.09302325
Subtracting 3010 from 3360 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Our division results in 136104.09302325 with a remaining 3.5e-07.
