We look at the division of 17978650 by 602 
Let's see how many times 602 fits into 17978650.

Advancing to step 1:
When dividing 1 by 602, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 602

Going ahead to step 2:
602 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 602

Let's proceed to step 3:
When dividing 179 by 602, we get 0 with a remainder of 179.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 179 after subtracting 0 from 179.
Grab the next digit (7) from the dividend, add it to 179, then carry on: 1797 / 602

Step 4:
602 can be fit into 1797 2 times, resulting in a remainder of 593.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 593 after subtracting 1204 from 1797.
Take the next digit (8) from the dividend and append it to 593, then repeat: 5938 / 602

Step 5:
602 can be fit into 5938 9 times, resulting in a remainder of 520.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 5418 away from 5938, we end up with 520.
Fetch the next digit (6) from the dividend, attach it to 520 and continue: 5206 / 602

Moving on to step 6:
When dividing 5206 by 602, we get 8 with a remainder of 390.
Write down 8 as next digit of the result. 
Result so far: 298.0
Subtracting 4816 from 5206 leaves us with 390.
Take the next digit (5) from the dividend and append it to 390, then repeat: 3905 / 602

Advancing to step 7:
602 can be fit into 3905 6 times, resulting in a remainder of 293.
The next digit of our result is 6. 
Result so far: 2986.0
The remainder is 293 after subtracting 3612 from 3905.
Take the next digit (0) from the dividend and append it to 293, then repeat: 2930 / 602

Moving on to step 8:
602 goes into 2930 4 times with a remainder of 522.
Use 4 as the next digit of our solution. 
Result so far: 29864.0
If we take 2408 away from 2930, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Moving on to step 9:
602 can be fit into 5220 8 times, resulting in a remainder of 404.
Put 8 as the next digit of the answer. 
Result so far: 29864.8
The remainder is 404 after subtracting 4816 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 10:
If we divide 4040 by 602, we get 6 and a remainder of 428.
Write down 6 as next digit of the result. 
Result so far: 29864.86
Deduct 3612 from 4040 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 11:
602 goes into 4280 7 times with a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 29864.867
Subtracting 4214 from 4280 leaves us 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.

Step 12:
The number 602 fits into 660 1 times, leaving a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 29864.8671
If we subtract 602 from 660, we 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.

Moving on to step 13:
When dividing 580 by 602, we get 0 with a remainder of 580.
Write down 0 as next digit of the result. 
Result so far: 29864.8671
If we subtract 0 from 580, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 14:
When dividing 5800 by 602, we get 9 with a remainder of 382.
Write down 9 as next digit of the result. 
Result so far: 29864.867109
Subtract 5418 from 5800 to 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.

On to step 15:
602 goes into 3820 6 times with a remainder of 208.
The number 6 becomes the next digit in our result. 
Result so far: 29864.8671096
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 16:
The number 602 fits into 2080 3 times, leaving a remainder of 274.
Put 3 as the next digit of the answer. 
Result so far: 29864.86710963
The remainder is 274 after subtracting 1806 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

The final outcome is 29864.86710963, with a leftover of 2.74e-07.
