Let's divide 545603 by 4
We want to figure out the number of times 545603 can be divided by 4.

Step 1:
4 can be fit into 5 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 4 from 5 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 4

Let's proceed to step 2:
4 goes into 14 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 12 from 14, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 4

Going ahead to step 3:
25 divided by 4 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 136.0
The remainder is 1 after subtracting 24 from 25.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 4

Let's proceed to step 4:
If we divide 16 by 4, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 1364.0
The remainder is 0 after subtracting 16 from 16.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Moving on to step 5:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13640.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 4

On to step 6:
3 divided by 4 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 136400.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
30 divided by 4 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 136400.7
Deduct 28 from 30 and we're left 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.

On to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 136400.75
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.

Moving on to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 136400.75
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.

Step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 136400.75
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 136400.75, with a leftover of 0.0.
