Let's divide 428407 by 4
Let's see how many times 4 fits into 428407.

Going ahead to step 1:
4 goes into 4 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 4

On to step 2:
When dividing 2 by 4, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 4

On to step 3:
4 goes into 28 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtracting 28 from 28 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 4

Let's proceed to step 4:
If we divide 4 by 4, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1071.0
Deduct 4 from 4 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 4

Let's proceed to step 5:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10710.0
Subtract 0 from 0 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 4

Moving on to step 6:
4 can be fit into 7 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 107101.0
Subtract 4 from 7 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 4 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 107101.7
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
20 divided by 4 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 107101.75
If we subtract 20 from 20, we 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.

Advancing to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 107101.75
If we subtract 0 from 0, we 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.

On to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 107101.75
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 outcome is 107101.75, with a leftover of 0.0.
