415965 divided by 4 
Let's see how many times 4 fits into 415965.

On to step 1:
4 goes into 4 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 4 from 4, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 4

Going ahead to step 2:
If we divide 1 by 4, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 4

Let's proceed to step 3:
If we divide 15 by 4, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 103.0
Deduct 12 from 15 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 4

On to step 4:
4 can be fit into 39 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 1039.0
If we subtract 36 from 39, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 4

Going ahead to step 5:
If we divide 36 by 4, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 10399.0
Deduct 36 from 36 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 4

On to step 6:
4 goes into 5 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 103991.0
Subtract 4 from 5 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 4 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 103991.2
Subtract 8 from 10 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.

Advancing to step 8:
4 goes into 20 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 103991.25
Deduct 20 from 20 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.

Going ahead to step 9:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 103991.25
Deduct 0 from 0 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.

Going ahead to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 103991.25
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.

The final result is 103991.25 with a remainder of 0.0.
