Let's divide 162170 by 42
Let's see how many times 42 fits into 162170.

Step 1:
The number 42 fits into 1 0 times, leaving 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.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 42

Let's proceed to step 2:
The number 42 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 42

Let's proceed to step 3:
When dividing 162 by 42, we get 3 with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 126 from 162 leaves us with 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 42

Let's proceed to step 4:
42 goes into 361 8 times with a remainder of 25.
The next digit of our result is 8. 
Result so far: 38.0
The remainder is 25 after subtracting 336 from 361.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 42

Step 5:
257 divided by 42 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 386.0
Subtract 252 from 257 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 42

Moving on to step 6:
42 can be fit into 50 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 3861.0
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
When dividing 80 by 42, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 3861.1
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 3861.19
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3861.19
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
When dividing 200 by 42, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 3861.1904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 3861.19047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 3861.190476
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
42 goes into 80 1 times with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 3861.1904761
If we subtract 42 from 80, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
If we divide 380 by 42, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 3861.19047619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 3861.19047619 with a remainder of 2e-09.
