We divide 437359 by 42
Let's see how many times 42 fits into 437359.

On to step 1:
42 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 42

Going ahead to step 2:
The number 42 fits into 43 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 42 from 43 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 42

Advancing to step 3:
42 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 17, we get 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 42

On to step 4:
173 divided by 42 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 104.0
If we take 168 away from 173, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 42

Step 5:
55 divided by 42 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1041.0
Subtracting 42 from 55 leaves us with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 42

Let's proceed to step 6:
The number 42 fits into 139 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 10413.0
If we subtract 126 from 139, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
130 divided by 42 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 10413.3
If we subtract 126 from 130, 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.

Going ahead to step 8:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10413.3
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
If we divide 400 by 42, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 10413.309
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
The number 42 fits into 220 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 10413.3095
If we subtract 210 from 220, 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.

On to step 11:
100 divided by 42 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 10413.30952
Subtract 84 from 100 to 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.

On to step 12:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 10413.309523
The remainder is 34 after subtracting 126 from 160.
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 13:
If we divide 340 by 42, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10413.3095238
Deduct 336 from 340 and we're left with 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 14:
42 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 10413.3095238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 10413.3095238, with a leftover of 4e-08.
