18408128 ÷ 598 
Let's see how many times 598 fits into 18408128.

On to step 1:
598 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 598

Moving on to step 2:
598 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 598

Advancing to step 3:
If we divide 184 by 598, we get 0 and a remainder of 184.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 184 leaves us with 184.
Include the next digit (0) from the dividend after 184, then repeat: 1840 / 598

Going ahead to step 4:
The number 598 fits into 1840 3 times, leaving a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 46 after subtracting 1794 from 1840.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 598

On to step 5:
598 can be fit into 468 0 times, resulting in a remainder of 468.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 468 and we're left with 468.
Append the next digit (1) from the dividend to 468 and continue with: 4681 / 598

Step 6:
598 can be fit into 4681 7 times, resulting in a remainder of 495.
Use 7 as the next digit of our solution. 
Result so far: 307.0
Deduct 4186 from 4681 and we're left with 495.
Append the next digit (2) from the dividend to 495 and continue with: 4952 / 598

Advancing to step 7:
When dividing 4952 by 598, we get 8 with a remainder of 168.
Write down 8 as next digit of the result. 
Result so far: 3078.0
Subtracting 4784 from 4952 leaves us with 168.
Bring next digit (8) of the dividend behind the 168 and repeat the process: 1688 / 598

On to step 8:
When dividing 1688 by 598, we get 2 with a remainder of 492.
Record the quotient 2 as the next digit in the result. 
Result so far: 30782.0
The remainder is 492 after subtracting 1196 from 1688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Advancing to step 9:
598 goes into 4920 8 times with a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 30782.8
The remainder is 136 after subtracting 4784 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
If we divide 1360 by 598, we get 2 and a remainder of 164.
The next digit of our result is 2. 
Result so far: 30782.82
Subtract 1196 from 1360 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 11:
If we divide 1640 by 598, we get 2 and a remainder of 444.
Put 2 as the next digit of the answer. 
Result so far: 30782.822
Deduct 1196 from 1640 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

The quotient of the division is 30782.822, and the remainder is 0.0444.
