Moving on to step 2:
42 divided by 602 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 602

On to step 3:
602 goes into 428 0 times with a remainder of 428.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 428, we end up with 428.
Fetch the next digit (7) from the dividend, attach it to 428 and continue: 4287 / 602

Moving on to step 4:
602 can be fit into 4287 7 times, resulting in a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 4214 from 4287 leaves us with 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 602

Let's proceed to step 5:
When dividing 739 by 602, we get 1 with a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Deduct 602 from 739 and we're left with 137.
Fetch the next digit (9) from the dividend, attach it to 137 and continue: 1379 / 602

Moving on to step 6:
1379 divided by 602 is 2 with a remainder of 175.
Write down 2 as next digit of the result. 
Result so far: 712.0
The remainder is 175 after subtracting 1204 from 1379.
Fetch the next digit (8) from the dividend, attach it to 175 and continue: 1758 / 602

Moving on to step 7:
602 goes into 1758 2 times with a remainder of 554.
Use 2 as the next digit of our solution. 
Result so far: 7122.0
Subtracting 1204 from 1758 leaves us with 554.
Grab the next digit (5) from the dividend, add it to 554, then carry on: 5545 / 602

Let's proceed to step 8:
The number 602 fits into 5545 9 times, leaving a remainder of 127.
Put 9 as the next digit of the answer. 
Result so far: 71229.0
Subtract 5418 from 5545 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 9:
If we divide 1270 by 602, we get 2 and a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 71229.2
Deduct 1204 from 1270 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
When dividing 660 by 602, we get 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 71229.21
Subtract 602 from 660 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
If we divide 580 by 602, we get 0 and a remainder of 580.
The number 0 becomes the next digit in our result. 
Result so far: 71229.21
Deduct 0 from 580 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 12:
5800 divided by 602 is 9 with a remainder of 382.
Use 9 as the next digit of our solution. 
Result so far: 71229.2109
If we subtract 5418 from 5800, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 13:
602 goes into 3820 6 times with a remainder of 208.
Record the quotient 6 as the next digit in the result. 
Result so far: 71229.21096
Subtracting 3612 from 3820 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 14:
602 goes into 2080 3 times with a remainder of 274.
The number 3 becomes the next digit in our result. 
Result so far: 71229.210963
If we take 1806 away from 2080, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 15:
602 can be fit into 2740 4 times, resulting in a remainder of 332.
Use 4 as the next digit of our solution. 
Result so far: 71229.2109634
If we subtract 2408 from 2740, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 16:
602 goes into 3320 5 times with a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 71229.21096345
The remainder is 310 after subtracting 3010 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final result is 71229.21096345 with a remainder of 3.1e-07.
