420917 ÷ 10 
Let's see how many times 10 fits into 420917.

Let's proceed to step 1:
4 divided by 10 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 10

Going ahead to step 2:
42 divided by 10 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 40 from 42 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 10

Step 3:
10 goes into 20 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 20 from 20 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 10

Step 4:
10 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 420.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 10

Moving on to step 5:
If we divide 91 by 10, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 4209.0
Subtract 90 from 91 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 10

Let's proceed to step 6:
10 goes into 17 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 42091.0
Deduct 10 from 17 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
10 goes into 70 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 42091.7
Deduct 70 from 70 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.

Let's proceed to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42091.7
If we take 0 away from 0, we end up 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:
When dividing 0 by 10, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42091.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 42091.7 with a remaining 0.0.
