We divide 78291810 by 790
We want to figure out the number of times 78291810 can be divided by 790.

Going ahead to step 1:
790 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 790

On to step 2:
The number 790 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 790

Advancing to step 3:
If we divide 782 by 790, we get 0 and a remainder of 782.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 782, we end up with 782.
Bring next digit (9) of the dividend behind the 782 and repeat the process: 7829 / 790

Moving on to step 4:
790 goes into 7829 9 times with a remainder of 719.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7110 from 7829 leaves us with 719.
Include the next digit (1) from the dividend after 719, then repeat: 7191 / 790

Let's proceed to step 5:
If we divide 7191 by 790, we get 9 and a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 99.0
The remainder is 81 after subtracting 7110 from 7191.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 790

Step 6:
818 divided by 790 is 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 991.0
The remainder is 28 after subtracting 790 from 818.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 790

Let's proceed to step 7:
When dividing 281 by 790, we get 0 with a remainder of 281.
The number 0 becomes the next digit in our result. 
Result so far: 9910.0
Subtracting 0 from 281 leaves us with 281.
Include the next digit (0) from the dividend after 281, then repeat: 2810 / 790

On to step 8:
2810 divided by 790 is 3 with a remainder of 440.
The number 3 becomes the next digit in our result. 
Result so far: 99103.0
The remainder is 440 after subtracting 2370 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 9:
790 goes into 4400 5 times with a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 99103.5
If we take 3950 away from 4400, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 10:
790 goes into 4500 5 times with a remainder of 550.
Write down 5 as next digit of the result. 
Result so far: 99103.55
If we subtract 3950 from 4500, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

After the division, we end up with 99103.55 and a remainder of 0.55.
