We're dividing 170647 by 42 
We want to divide 170647 by 42.

Going ahead to step 1:
42 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 42

Step 2:
17 divided by 42 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 42

Let's proceed to step 3:
170 divided by 42 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 168 from 170 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 42

Step 4:
The number 42 fits into 26 0 times, leaving a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 26 and we're left with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 42

Going ahead to step 5:
When dividing 264 by 42, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 406.0
If we take 252 away from 264, we end up with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 42

Advancing to step 6:
When dividing 127 by 42, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 4063.0
The remainder is 1 after subtracting 126 from 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
42 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4063.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
42 goes into 100 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 4063.02
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
42 goes into 160 3 times with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 4063.023
Subtract 126 from 160 to 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.

Advancing to step 10:
When dividing 340 by 42, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 4063.0238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
If we divide 40 by 42, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4063.0238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
42 goes into 400 9 times with a remainder of 22.
The next digit of our result is 9. 
Result so far: 4063.023809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
42 goes into 220 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 4063.0238095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 4063.02380952
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 4063.02380952 and a remainder of 1.6e-08.
