928 divided by 143 is 6 with a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtract 858 from 928 to get 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 143

Going ahead to step 5:
If we divide 700 by 143, we get 4 and a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 464.0
If we subtract 572 from 700, we get 128.
Fetch the next digit (7) from the dividend, attach it to 128 and continue: 1287 / 143

Advancing to step 6:
143 can be fit into 1287 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 4649.0
The remainder is 0 after subtracting 1287 from 1287.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 143

Moving on to step 7:
If we divide 6 by 143, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 46490.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 143

On to step 8:
65 divided by 143 is 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 464900.0
Subtracting 0 from 65 leaves us with 65.

Put 4 as the next digit of the answer. 
Result so far: 464900.4
Deduct 572 from 650 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 10:
780 divided by 143 is 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 464900.45
The remainder is 65 after subtracting 715 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
If we divide 650 by 143, we get 4 and a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 464900.454
Subtract 572 from 650 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 12:
When dividing 780 by 143, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 464900.4545
Subtracting 715 from 780 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 13:
143 goes into 650 4 times with a remainder of 78.
The next digit of our result is 4. 
Result so far: 464900.45454
Deduct 572 from 650 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 14:
143 can be fit into 780 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 464900.454545
Subtract 715 from 780 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 15:
When dividing 650 by 143, we get 4 with a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 464900.4545454
If we take 572 away from 650, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 16:
143 can be fit into 780 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 464900.45454545
If we take 715 away from 780, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.
