78139073 ÷ 813 
Let's see how many times 813 fits into 78139073.

Going ahead to step 1:
The number 813 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 813

Advancing to step 2:
78 divided by 813 is 0 with 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.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 813

Let's proceed to step 3:
The number 813 fits into 781 0 times, leaving a remainder of 781.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 781 and we're left with 781.
Include the next digit (3) from the dividend after 781, then repeat: 7813 / 813

Moving on to step 4:
7813 divided by 813 is 9 with a remainder of 496.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 496 after subtracting 7317 from 7813.
Take the next digit (9) from the dividend and append it to 496, then repeat: 4969 / 813

Let's proceed to step 5:
The number 813 fits into 4969 6 times, leaving a remainder of 91.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Subtract 4878 from 4969 to get 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 813

On to step 6:
If we divide 910 by 813, we get 1 and a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 961.0
Subtracting 813 from 910 leaves us with 97.
Take the next digit (7) from the dividend and append it to 97, then repeat: 977 / 813

Going ahead to step 7:
813 goes into 977 1 times with a remainder of 164.
The number 1 becomes the next digit in our result. 
Result so far: 9611.0
Subtract 813 from 977 to get 164.
Append the next digit (3) from the dividend to 164 and continue with: 1643 / 813

Going ahead to step 8:
1643 divided by 813 is 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 96112.0
If we subtract 1626 from 1643, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
When dividing 170 by 813, we get 0 with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 96112.0
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
When dividing 1700 by 813, we get 2 with a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 96112.02
Subtract 1626 from 1700 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
813 goes into 740 0 times with a remainder of 740.
Put 0 as the next digit of the answer. 
Result so far: 96112.02
Subtracting 0 from 740 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 12:
When dividing 7400 by 813, we get 9 with a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 96112.0209
Subtracting 7317 from 7400 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 13:
830 divided by 813 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 96112.02091
Subtract 813 from 830 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
170 divided by 813 is 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 96112.02091
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 15:
813 can be fit into 1700 2 times, resulting in a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 96112.0209102
Subtracting 1626 from 1700 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 16:
The number 813 fits into 740 0 times, leaving a remainder of 740.
The next digit of our result is 0. 
Result so far: 96112.0209102
The remainder is 740 after subtracting 0 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Our division results in 96112.0209102 with a remaining 7.4e-07.
