556638 divided by 4 
We're looking to find how many times 4 goes into 556638.

Advancing to step 1:
5 divided by 4 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 4 from 5 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 4

On to step 2:
4 can be fit into 15 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 12 away from 15, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 4

Moving on to step 3:
If we divide 36 by 4, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 139.0
If we take 36 away from 36, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 4

Going ahead to step 4:
6 divided by 4 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1391.0
If we take 4 away from 6, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 4

On to step 5:
When dividing 23 by 4, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 13915.0
Subtracting 20 from 23 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 4

Let's proceed to step 6:
4 goes into 38 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 139159.0
If we subtract 36 from 38, we 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:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 139159.5
Subtracting 20 from 20 leaves us 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.

Advancing to step 8:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 139159.5
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.

On to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 139159.5
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 139159.5 with a balance of 0.0.
