Let's divide 247980 by 42
Let's see how many times 42 fits into 247980.

On to step 1:
The number 42 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 42

Advancing to step 2:
24 divided by 42 is 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 42

Let's proceed to step 3:
247 divided by 42 is 5 with a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 37 after subtracting 210 from 247.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 42

Advancing to step 4:
42 can be fit into 379 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Subtracting 378 from 379 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 42

Advancing to step 5:
The number 42 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 590.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 42

Going ahead to step 6:
If we divide 180 by 42, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 5904.0
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 5904.2
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 5904.28
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
When dividing 240 by 42, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 5904.285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
300 divided by 42 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 5904.2857
If we take 294 away from 300, we end up 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.

Going ahead to step 11:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 5904.28571
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.

Going ahead to step 12:
180 divided by 42 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 5904.285714
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.

Advancing to step 13:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 5904.2857142
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 5904.28571428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 5904.28571428 with a remaining 2.4e-08.
