We divide 88603 by 4
We're looking to find how many times 4 goes into 88603.

Moving on to step 1:
4 can be fit into 8 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 4

Going ahead to step 2:
If we divide 8 by 4, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 8 from 8 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 4

Moving on to step 3:
6 divided by 4 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 221.0
Deduct 4 from 6 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 4

Advancing to step 4:
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: 2215.0
If we take 20 away from 20, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

Advancing to step 5:
If we divide 3 by 4, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 22150.0
If we subtract 0 from 3, we 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.

Moving on to step 6:
4 goes into 30 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 22150.7
Subtract 28 from 30 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.

On to step 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 22150.75
The remainder is 0 after subtracting 20 from 20.
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 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22150.75
The remainder is 0 after subtracting 0 from 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:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22150.75
The remainder is 0 after subtracting 0 from 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 22150.75, with a leftover of 0.0.
