We look at the division of 71851639 by 410 
Let's see how many times 410 fits into 71851639.

On to step 1:
If we divide 7 by 410, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 410

Advancing to step 2:
410 can be fit into 71 0 times, resulting in a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 410

Moving on to step 3:
The number 410 fits into 718 1 times, leaving a remainder of 308.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 410 from 718 and we're left with 308.
Fetch the next digit (5) from the dividend, attach it to 308 and continue: 3085 / 410

Advancing to step 4:
410 goes into 3085 7 times with a remainder of 215.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 2870 from 3085 and we're left with 215.
Append the next digit (1) from the dividend to 215 and continue with: 2151 / 410

Step 5:
The number 410 fits into 2151 5 times, leaving a remainder of 101.
The next digit of our result is 5. 
Result so far: 175.0
Subtracting 2050 from 2151 leaves us with 101.
Fetch the next digit (6) from the dividend, attach it to 101 and continue: 1016 / 410

Going ahead to step 6:
1016 divided by 410 is 2 with a remainder of 196.
The number 2 becomes the next digit in our result. 
Result so far: 1752.0
The remainder is 196 after subtracting 820 from 1016.
Take the next digit (3) from the dividend and append it to 196, then repeat: 1963 / 410

On to step 7:
410 goes into 1963 4 times with a remainder of 323.
Write down 4 as next digit of the result. 
Result so far: 17524.0
Deduct 1640 from 1963 and we're left with 323.
Bring next digit (9) of the dividend behind the 323 and repeat the process: 3239 / 410

Let's proceed to step 8:
410 can be fit into 3239 7 times, resulting in a remainder of 369.
Use 7 as the next digit of our solution. 
Result so far: 175247.0
The remainder is 369 after subtracting 2870 from 3239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Going ahead to step 9:
When dividing 3690 by 410, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 175247.9
If we subtract 3690 from 3690, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 410, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 175247.9
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
The number 410 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 175247.9
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 175247.9 and a remainder of 0.0.
