Let's divide 573789 by 42
Let's see how many times 42 fits into 573789.

On to step 1:
When dividing 5 by 42, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 42

On to step 2:
42 goes into 57 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 42 away from 57, we end up with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 42

Let's proceed to step 3:
The number 42 fits into 153 3 times, leaving a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 126 from 153 leaves us with 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 42

Advancing to step 4:
When dividing 277 by 42, we get 6 with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 136.0
The remainder is 25 after subtracting 252 from 277.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 42

Moving on to step 5:
42 goes into 258 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 1366.0
Subtracting 252 from 258 leaves us with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 42

On to step 6:
The number 42 fits into 69 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 13661.0
Subtracting 42 from 69 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
270 divided by 42 is 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 13661.6
Subtract 252 from 270 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 8:
180 divided by 42 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 13661.64
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 9:
If we divide 120 by 42, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 13661.642
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.

Step 10:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 13661.6428
Deduct 336 from 360 and we're left 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 11:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 13661.64285
Subtracting 210 from 240 leaves us 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.

Step 12:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 13661.642857
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.

Going ahead to step 13:
60 divided by 42 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 13661.6428571
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.

Moving on to step 14:
If we divide 180 by 42, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 13661.64285714
Subtracting 168 from 180 leaves us 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.

Our division results in 13661.64285714 with a remaining 1.2e-08.
