Let's proceed to step 3:
162 divided by 646 is 0 with a remainder of 162.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 162 after subtracting 0 from 162.
Grab the next digit (0) from the dividend, add it to 162, then carry on: 1620 / 646

On to step 4:
The number 646 fits into 1620 2 times, leaving a remainder of 328.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1292 from 1620 to get 328.
Fetch the next digit (8) from the dividend, attach it to 328 and continue: 3288 / 646

Step 5:
3288 divided by 646 is 5 with a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 3230 from 3288 to get 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 646

Advancing to step 6:
646 goes into 580 0 times with a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 250.0
If we subtract 0 from 580, we get 580.
Take the next digit (3) from the dividend and append it to 580, then repeat: 5803 / 646

Going ahead to step 7:
646 can be fit into 5803 8 times, resulting in a remainder of 635.
Write down 8 as next digit of the result. 
Result so far: 2508.0
If we take 5168 away from 5803, we end up with 635.
Fetch the next digit (8) from the dividend, attach it to 635 and continue: 6358 / 646

Moving on to step 8:
The number 646 fits into 6358 9 times, leaving a remainder of 544.
The next digit of our result is 9. 
Result so far: 25089.0
If we take 5814 away from 6358, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 9:
When dividing 5440 by 646, we get 8 with a remainder of 272.
Write down 8 as next digit of the result. 
Result so far: 25089.8
Deduct 5168 from 5440 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 10:
646 can be fit into 2720 4 times, resulting in a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 25089.84
Deduct 2584 from 2720 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 11:
If we divide 1360 by 646, we get 2 and a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 25089.842
If we subtract 1292 from 1360, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
If we divide 680 by 646, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 25089.8421
If we subtract 646 from 680, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
If we divide 340 by 646, we get 0 and a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 25089.8421
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 14:
3400 divided by 646 is 5 with a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 25089.842105
If we subtract 3230 from 3400, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 15:
1700 divided by 646 is 2 with a remainder of 408.
Record the quotient 2 as the next digit in the result. 
Result so far: 25089.8421052
Subtracting 1292 from 1700 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 16:
646 goes into 4080 6 times with a remainder of 204.
Record the quotient 6 as the next digit in the result. 
Result so far: 25089.84210526
Deduct 3876 from 4080 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The quotient of the division is 25089.84210526, and the remainder is 2.04e-07.
