We're dividing 17609471 by 42 
We want to figure out the number of times 17609471 can be divided by 42.

On to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 42

Let's proceed to step 2:
42 goes into 17 0 times with 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 (6) from the dividend after 17, then repeat: 176 / 42

Going ahead to step 3:
42 can be fit into 176 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 168 from 176 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 42

Advancing to step 4:
42 can be fit into 80 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 41.0
If we take 42 away from 80, we end up with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 42

Advancing to step 5:
389 divided by 42 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 419.0
Subtracting 378 from 389 leaves us with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 42

On to step 6:
42 can be fit into 114 2 times, resulting in a remainder of 30.
The next digit of our result is 2. 
Result so far: 4192.0
The remainder is 30 after subtracting 84 from 114.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 42

Advancing to step 7:
307 divided by 42 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 41927.0
Deduct 294 from 307 and we're left with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 42

Going ahead to step 8:
If we divide 131 by 42, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 419273.0
The remainder is 5 after subtracting 126 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
50 divided by 42 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 419273.1
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 419273.11
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 419273.11, and the remainder is 0.038.
