We look at the division of 606428 by 40 
We want to figure out the number of times 606428 can be divided by 40.

Let's proceed to step 1:
6 divided by 40 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 40

Let's proceed to step 2:
60 divided by 40 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 20 after subtracting 40 from 60.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 40

Moving on to step 3:
40 goes into 206 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 200 from 206 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 40

Advancing to step 4:
If we divide 64 by 40, we get 1 and a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 151.0
The remainder is 24 after subtracting 40 from 64.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 40

On to step 5:
40 can be fit into 242 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 1516.0
Subtract 240 from 242 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 40

Going ahead to step 6:
40 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 15160.0
Subtract 0 from 28 to 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.

Going ahead to step 7:
The number 40 fits into 280 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 15160.7
Subtracting 280 from 280 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 40, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15160.7
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 15160.7
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 15160.7 with a balance of 0.0.
