We look at the division of 407417 by 42 
We want to figure out the number of times 407417 can be divided by 42.

Going ahead to step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 42

On to step 2:
If we divide 40 by 42, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 42

Let's proceed to step 3:
42 can be fit into 407 9 times, resulting in a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 378 from 407 leaves us with 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 42

Advancing to step 4:
42 goes into 294 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 97.0
Subtract 294 from 294 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 42

Step 5:
42 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 970.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 42

On to step 6:
42 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 9700.0
Deduct 0 from 17 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
When dividing 170 by 42, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 9700.4
If we subtract 168 from 170, we 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.

On to step 8:
When dividing 20 by 42, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9700.4
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 42, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 9700.404
If we subtract 168 from 200, we 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 10:
When dividing 320 by 42, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 9700.4047
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.

Advancing to step 11:
If we divide 260 by 42, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 9700.40476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
80 divided by 42 is 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 9700.404761
Deduct 42 from 80 and we're left 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.

Advancing to step 13:
42 can be fit into 380 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 9700.4047619
If we subtract 378 from 380, we 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.

On to step 14:
20 divided by 42 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9700.4047619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 9700.4047619 and a remainder of 2e-08.
