Let's divide 86143067 by 409
We want to divide 86143067 by 409.

On to step 1:
When dividing 8 by 409, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 409

Let's proceed to step 2:
86 divided by 409 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 409

Moving on to step 3:
861 divided by 409 is 2 with a remainder of 43.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 818 from 861, we get 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 409

Step 4:
If we divide 434 by 409, we get 1 and a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 25 after subtracting 409 from 434.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 409

Let's proceed to step 5:
253 divided by 409 is 0 with a remainder of 253.
Use 0 as the next digit of our solution. 
Result so far: 210.0
If we subtract 0 from 253, we get 253.
Grab the next digit (0) from the dividend, add it to 253, then carry on: 2530 / 409

Going ahead to step 6:
When dividing 2530 by 409, we get 6 with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 2106.0
Subtract 2454 from 2530 to get 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 409

Moving on to step 7:
409 goes into 766 1 times with a remainder of 357.
Put 1 as the next digit of the answer. 
Result so far: 21061.0
Subtract 409 from 766 to get 357.
Fetch the next digit (7) from the dividend, attach it to 357 and continue: 3577 / 409

Going ahead to step 8:
If we divide 3577 by 409, we get 8 and a remainder of 305.
The number 8 becomes the next digit in our result. 
Result so far: 210618.0
Deduct 3272 from 3577 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 9:
The number 409 fits into 3050 7 times, leaving a remainder of 187.
Record the quotient 7 as the next digit in the result. 
Result so far: 210618.7
If we subtract 2863 from 3050, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 10:
If we divide 1870 by 409, we get 4 and a remainder of 234.
The next digit of our result is 4. 
Result so far: 210618.74
Deduct 1636 from 1870 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 11:
2340 divided by 409 is 5 with a remainder of 295.
Record the quotient 5 as the next digit in the result. 
Result so far: 210618.745
Subtract 2045 from 2340 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 12:
When dividing 2950 by 409, we get 7 with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 210618.7457
The remainder is 87 after subtracting 2863 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 13:
The number 409 fits into 870 2 times, leaving a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 210618.74572
Subtract 818 from 870 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 14:
When dividing 520 by 409, we get 1 with a remainder of 111.
The number 1 becomes the next digit in our result. 
Result so far: 210618.745721
Deduct 409 from 520 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 15:
409 goes into 1110 2 times with a remainder of 292.
Use 2 as the next digit of our solution. 
Result so far: 210618.7457212
Subtracting 818 from 1110 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 16:
2920 divided by 409 is 7 with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 210618.74572127
The remainder is 57 after subtracting 2863 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

In conclusion, the division gives 210618.74572127 with a balance of 5.7e-08.
