Let's divide 437310 by 42
We want to divide 437310 by 42.

Going ahead to step 1:
42 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 42

Step 2:
When dividing 43 by 42, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 43, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 42

Let's proceed to step 3:
When dividing 17 by 42, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 42

Going ahead to step 4:
173 divided by 42 is 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
The remainder is 5 after subtracting 168 from 173.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 42

Moving on to step 5:
If we divide 51 by 42, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1041.0
Subtracting 42 from 51 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 42

Moving on to step 6:
The number 42 fits into 90 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 10412.0
If we subtract 84 from 90, we 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.

Let's proceed to step 7:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 10412.1
Deduct 42 from 60 and we're left with 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:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 10412.14
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.

Let's proceed to step 9:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The next digit of our result is 2. 
Result so far: 10412.142
Deduct 84 from 120 and we're left 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.

Let's proceed to step 10:
42 goes into 360 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 10412.1428
If we take 336 away from 360, we end up 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.

Let's proceed to step 11:
If we divide 240 by 42, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 10412.14285
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.

On to step 12:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 10412.142857
If we subtract 294 from 300, we 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.

Let's proceed to step 13:
If we divide 60 by 42, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 10412.1428571
Deduct 42 from 60 and we're left with 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: 10412.14285714
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.

Our division results in 10412.14285714 with a remaining 1.2e-08.
