147216 ÷ 42 
Our goal is to divide 147216 by 42.

Advancing to step 1:
If we divide 1 by 42, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 42

On to step 2:
42 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 42

Advancing to step 3:
The number 42 fits into 147 3 times, leaving a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 21 after subtracting 126 from 147.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 42

Let's proceed to step 4:
212 divided by 42 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtract 210 from 212 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 42

Step 5:
If we divide 21 by 42, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 350.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 42

On to step 6:
216 divided by 42 is 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 3505.0
Deduct 210 from 216 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
42 goes into 60 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 3505.1
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 3505.14
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 3505.142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
360 divided by 42 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 3505.1428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 3505.14285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 3505.142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
42 goes into 60 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 3505.1428571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
When dividing 180 by 42, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 3505.14285714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 3505.14285714 with a remainder of 1.2e-08.
