97858216 ÷ 143 
Our goal is to divide 97858216 by 143.

Moving on to step 1:
When dividing 9 by 143, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 143

Step 2:
When dividing 97 by 143, we get 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Fetch the next digit (8) from the dividend, attach it to 97 and continue: 978 / 143

Going ahead to step 3:
When dividing 978 by 143, we get 6 with a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 858 away from 978, we end up with 120.
Grab the next digit (5) from the dividend, add it to 120, then carry on: 1205 / 143

Let's proceed to step 4:
1205 divided by 143 is 8 with a remainder of 61.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Subtracting 1144 from 1205 leaves us with 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 143

On to step 5:
143 goes into 618 4 times with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 684.0
If we take 572 away from 618, we end up with 46.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 143

Advancing to step 6:
The number 143 fits into 462 3 times, leaving a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 6843.0
Subtracting 429 from 462 leaves us with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 143

On to step 7:
The number 143 fits into 331 2 times, leaving a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 68432.0
Deduct 286 from 331 and we're left with 45.
Grab the next digit (6) from the dividend, add it to 45, then carry on: 456 / 143

Let's proceed to step 8:
When dividing 456 by 143, we get 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 684323.0
Subtract 429 from 456 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
143 can be fit into 270 1 times, resulting in a remainder of 127.
Record the quotient 1 as the next digit in the result. 
Result so far: 684323.1
If we subtract 143 from 270, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 10:
143 can be fit into 1270 8 times, resulting in a remainder of 126.
Put 8 as the next digit of the answer. 
Result so far: 684323.18
Deduct 1144 from 1270 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 11:
The number 143 fits into 1260 8 times, leaving a remainder of 116.
The next digit of our result is 8. 
Result so far: 684323.188
If we take 1144 away from 1260, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final result is 684323.188 with a remainder of 0.0116.
