143898 ÷ 17 
We want to divide 143898 by 17.

Step 1:
17 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 17

On to step 2:
14 divided by 17 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 17

Advancing to step 3:
The number 17 fits into 143 8 times, leaving a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 136 from 143 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 17

Moving on to step 4:
78 divided by 17 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 84.0
Subtracting 68 from 78 leaves us with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 17

On to step 5:
When dividing 109 by 17, we get 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 846.0
The remainder is 7 after subtracting 102 from 109.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 17

Going ahead to step 6:
If we divide 78 by 17, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 8464.0
Deduct 68 from 78 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
17 can be fit into 100 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 8464.5
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
When dividing 150 by 17, we get 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 8464.58
Deduct 136 from 150 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
140 divided by 17 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 8464.588
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 8464.588 and a remainder of 0.0004.
