17554021 ÷ 4 
We're looking to find how many times 4 goes into 17554021.

Moving on to step 1:
When dividing 1 by 4, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 4

Let's proceed to step 2:
The number 4 fits into 17 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 16 from 17 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 4

Advancing 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: 43.0
Subtracting 12 from 15 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 4

Moving on to step 4:
4 can be fit into 35 8 times, resulting in a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 438.0
Subtracting 32 from 35 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 4

Advancing to step 5:
34 divided by 4 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 4388.0
Subtracting 32 from 34 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 4

On to step 6:
If we divide 20 by 4, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 43885.0
Subtract 20 from 20 to get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 4

On to step 7:
When dividing 2 by 4, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 438850.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 4

Moving on to step 8:
21 divided by 4 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 4388505.0
Subtract 20 from 21 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.

On to step 9:
4 goes into 10 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 4388505.2
If we subtract 8 from 10, 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.

Advancing to step 10:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 4388505.25
If we take 20 away from 20, we end up 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 11:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4388505.25
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.

Going ahead to step 12:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4388505.25
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.

In conclusion, the division gives 4388505.25 with a balance of 0.0.
