We look at the division of 615211 by 42 
We want to figure out the number of times 615211 can be divided by 42.

Moving on to step 1:
42 goes into 6 0 times 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.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 42

Step 2:
61 divided by 42 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 42 from 61, we get 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 42

Let's proceed to step 3:
42 goes into 195 4 times with a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 27 after subtracting 168 from 195.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 42

Going ahead to step 4:
42 goes into 272 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 146.0
Deduct 252 from 272 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 42

Let's proceed to step 5:
When dividing 201 by 42, we get 4 with a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 1464.0
If we take 168 away from 201, we end up with 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 42

Moving on to step 6:
42 can be fit into 331 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 14647.0
Deduct 294 from 331 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
If we divide 370 by 42, we get 8 and a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 14647.8
Subtract 336 from 370 to get 34.
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 8:
If we divide 340 by 42, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 14647.88
If we take 336 away from 340, we end up 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.

The final result is 14647.88 with a remainder of 0.004.
