Let's divide 143786 by 209
We want to divide 143786 by 209.

Step 1:
If we divide 1 by 209, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 209

Moving on to step 2:
If we divide 14 by 209, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 209

Going ahead to step 3:
When dividing 143 by 209, we get 0 with a remainder of 143.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 143, we get 143.
Take the next digit (7) from the dividend and append it to 143, then repeat: 1437 / 209

Going ahead to step 4:
209 goes into 1437 6 times with a remainder of 183.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 1254 from 1437 and we're left with 183.
Grab the next digit (8) from the dividend, add it to 183, then carry on: 1838 / 209

On to step 5:
If we divide 1838 by 209, we get 8 and a remainder of 166.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
If we take 1672 away from 1838, we end up with 166.
Grab the next digit (6) from the dividend, add it to 166, then carry on: 1666 / 209

Advancing to step 6:
209 goes into 1666 7 times with a remainder of 203.
Record the quotient 7 as the next digit in the result. 
Result so far: 687.0
Subtract 1463 from 1666 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 7:
2030 divided by 209 is 9 with a remainder of 149.
The next digit of our result is 9. 
Result so far: 687.9
Deduct 1881 from 2030 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 8:
If we divide 1490 by 209, we get 7 and a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 687.97
If we take 1463 away from 1490, we end up with 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:
When dividing 270 by 209, we get 1 with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 687.971
Deduct 209 from 270 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 10:
209 can be fit into 610 2 times, resulting in a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 687.9712
If we subtract 418 from 610, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 11:
If we divide 1920 by 209, we get 9 and a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 687.97129
If we subtract 1881 from 1920, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 12:
390 divided by 209 is 1 with a remainder of 181.
Use 1 as the next digit of our solution. 
Result so far: 687.971291
Subtracting 209 from 390 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 13:
When dividing 1810 by 209, we get 8 with a remainder of 138.
Record the quotient 8 as the next digit in the result. 
Result so far: 687.9712918
The remainder is 138 after subtracting 1672 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 14:
The number 209 fits into 1380 6 times, leaving a remainder of 126.
Record the quotient 6 as the next digit in the result. 
Result so far: 687.97129186
If we take 1254 away from 1380, we end up 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.

After the division, we end up with 687.97129186 and a remainder of 1.26e-07.
