We look at the division of 17013191 by 42 
Our goal is to divide 17013191 by 42.

Advancing to step 1:
1 divided by 42 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 42

On to step 2:
If we divide 17 by 42, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 42

Step 3:
If we divide 170 by 42, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 2 after subtracting 168 from 170.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 42

Step 4:
When dividing 21 by 42, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 21 to get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 42

Going ahead to step 5:
213 divided by 42 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 405.0
Subtract 210 from 213 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 42

Moving on to step 6:
31 divided by 42 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 4050.0
Subtracting 0 from 31 leaves us with 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 42

Moving on to step 7:
The number 42 fits into 319 7 times, leaving a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 40507.0
Subtracting 294 from 319 leaves us with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 42

Step 8:
42 goes into 251 5 times with a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 405075.0
Subtracting 210 from 251 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
When dividing 410 by 42, we get 9 with a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 405075.9
Subtracting 378 from 410 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
42 goes into 320 7 times with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 405075.97
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
When dividing 260 by 42, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 405075.976
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 405075.9761
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 405075.97619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
When dividing 20 by 42, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 405075.97619
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
If we divide 200 by 42, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 405075.9761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
42 can be fit into 320 7 times, resulting in a remainder of 26.
The next digit of our result is 7. 
Result so far: 405075.97619047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 405075.97619047 with a balance of 2.6e-08.
