99143 ÷ 7 
We want to divide 99143 by 7.

Step 1:
9 divided by 7 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 7 from 9 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 7

Going ahead to step 2:
If we divide 29 by 7, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 1 after subtracting 28 from 29.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 7

Going ahead to step 3:
11 divided by 7 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
If we subtract 7 from 11, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 7

On to step 4:
The number 7 fits into 44 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 1416.0
If we subtract 42 from 44, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 7

Step 5:
The number 7 fits into 23 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 14163.0
The remainder is 2 after subtracting 21 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
7 goes into 20 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 14163.2
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 14163.28
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 7, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 14163.285
Deduct 35 from 40 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
7 goes into 50 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 14163.2857
Subtract 49 from 50 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.

Advancing to step 10:
When dividing 10 by 7, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 14163.28571
If we subtract 7 from 10, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 14163.285714
Subtracting 28 from 30 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 14163.2857142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 14163.28571428
Subtract 56 from 60 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.

The quotient of the division is 14163.28571428, and the remainder is 4e-09.
