We divide 164515 by 42
We want to divide 164515 by 42.

On to step 1:
1 divided by 42 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 42

Step 2:
The number 42 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 42

On to step 3:
If we divide 164 by 42, we get 3 and a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 126 from 164 to get 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 42

Let's proceed to step 4:
When dividing 385 by 42, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 378 from 385 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 42

Step 5:
If we divide 71 by 42, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 391.0
The remainder is 29 after subtracting 42 from 71.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 42

Let's proceed to step 6:
When dividing 295 by 42, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 3917.0
Subtracting 294 from 295 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
42 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3917.0
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:
When dividing 100 by 42, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 3917.02
Deduct 84 from 100 and we're left 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:
If we divide 160 by 42, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 3917.023
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 3917.0238
If we subtract 336 from 340, we 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:
42 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 3917.0238
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 3917.023809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 3917.0238095
If we take 210 away from 220, we end up with 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 goes into 100 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 3917.02380952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 3917.02380952 with a balance of 1.6e-08.
