We look at the division of 737401 by 42 
We're looking to find how many times 42 goes into 737401.

Step 1:
42 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 42

On to step 2:
The number 42 fits into 73 1 times, leaving a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 31 after subtracting 42 from 73.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 42

Going ahead to step 3:
42 goes into 317 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 17.0
If we take 294 away from 317, we end up with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 42

Going ahead to step 4:
The number 42 fits into 234 5 times, leaving a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 175.0
The remainder is 24 after subtracting 210 from 234.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 42

On to step 5:
42 goes into 240 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 1755.0
Subtracting 210 from 240 leaves us with 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 42

Let's proceed to step 6:
The number 42 fits into 301 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 17557.0
The remainder is 7 after subtracting 294 from 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 42, we get 1 and a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 17557.1
Subtracting 42 from 70 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
If we divide 280 by 42, we get 6 and a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 17557.16
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
When dividing 280 by 42, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 17557.166
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 17557.166 with a remainder of 0.0028.
