We look at the division of 30868701 by 143 
Our goal is to divide 30868701 by 143.

Let's proceed to step 1:
3 divided by 143 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 143

Let's proceed to step 2:
143 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 143

Moving on to step 3:
If we divide 308 by 143, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 286 from 308 to get 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 143

Moving on to step 4:
If we divide 226 by 143, we get 1 and a remainder of 83.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 143 away from 226, we end up with 83.
Append the next digit (8) from the dividend to 83 and continue with: 838 / 143

Moving on to step 5:
838 divided by 143 is 5 with a remainder of 123.
Put 5 as the next digit of the answer. 
Result so far: 215.0
If we take 715 away from 838, we end up with 123.
Append the next digit (7) from the dividend to 123 and continue with: 1237 / 143

Moving on to step 6:
The number 143 fits into 1237 8 times, leaving a remainder of 93.
Put 8 as the next digit of the answer. 
Result so far: 2158.0
If we take 1144 away from 1237, we end up with 93.
Take the next digit (0) from the dividend and append it to 93, then repeat: 930 / 143

Going ahead to step 7:
930 divided by 143 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 21586.0
If we take 858 away from 930, we end up with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 143

Let's proceed to step 8:
When dividing 721 by 143, we get 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 215865.0
If we subtract 715 from 721, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
When dividing 60 by 143, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 215865.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
If we divide 600 by 143, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 215865.04
Subtracting 572 from 600 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
143 goes into 280 1 times with a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 215865.041
If we subtract 143 from 280, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 12:
If we divide 1370 by 143, we get 9 and a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 215865.0419
Deduct 1287 from 1370 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 13:
The number 143 fits into 830 5 times, leaving a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 215865.04195
If we subtract 715 from 830, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 14:
143 can be fit into 1150 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 215865.041958
If we subtract 1144 from 1150, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 15:
143 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 215865.041958
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 16:
When dividing 600 by 143, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 215865.04195804
Subtracting 572 from 600 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 215865.04195804 with a remaining 2.8e-08.
