73102086 divided by 781 
Our goal is to divide 73102086 by 781.

Advancing to step 1:
When dividing 7 by 781, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 781

Advancing to step 2:
73 divided by 781 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 781

Moving on to step 3:
The number 781 fits into 731 0 times, leaving a remainder of 731.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 731, we get 731.
Include the next digit (0) from the dividend after 731, then repeat: 7310 / 781

Step 4:
The number 781 fits into 7310 9 times, leaving a remainder of 281.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 281 after subtracting 7029 from 7310.
Grab the next digit (2) from the dividend, add it to 281, then carry on: 2812 / 781

Let's proceed to step 5:
If we divide 2812 by 781, we get 3 and a remainder of 469.
The next digit of our result is 3. 
Result so far: 93.0
Subtracting 2343 from 2812 leaves us with 469.
Take the next digit (0) from the dividend and append it to 469, then repeat: 4690 / 781

Step 6:
781 goes into 4690 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 936.0
Subtracting 4686 from 4690 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 781

Step 7:
781 can be fit into 48 0 times, resulting in a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 9360.0
If we take 0 away from 48, we end up with 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 781

Let's proceed to step 8:
781 goes into 486 0 times with a remainder of 486.
The next digit of our result is 0. 
Result so far: 93600.0
Deduct 0 from 486 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 9:
781 can be fit into 4860 6 times, resulting in a remainder of 174.
Write down 6 as next digit of the result. 
Result so far: 93600.6
The remainder is 174 after subtracting 4686 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 10:
781 can be fit into 1740 2 times, resulting in a remainder of 178.
Write down 2 as next digit of the result. 
Result so far: 93600.62
Subtracting 1562 from 1740 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 11:
1780 divided by 781 is 2 with a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 93600.622
The remainder is 218 after subtracting 1562 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Our division results in 93600.622 with a remaining 0.0218.
