Let's divide 77803723 by 13
We want to figure out the number of times 77803723 can be divided by 13.

Step 1:
If we divide 7 by 13, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 13

Step 2:
When dividing 77 by 13, we get 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 65 from 77, we get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 13

Going ahead to step 3:
128 divided by 13 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we subtract 117 from 128, we get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 13

Step 4:
110 divided by 13 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 598.0
Subtract 104 from 110 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 13

Let's proceed to step 5:
The number 13 fits into 63 4 times, leaving a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 5984.0
Subtract 52 from 63 to get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 13

Advancing to step 6:
13 can be fit into 117 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 59849.0
Deduct 117 from 117 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 13

Let's proceed to step 7:
2 divided by 13 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 598490.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 13

Step 8:
13 can be fit into 23 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 5984901.0
If we take 13 away from 23, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
13 goes into 100 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 5984901.7
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
90 divided by 13 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 5984901.76
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
120 divided by 13 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 5984901.769
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
If we divide 30 by 13, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 5984901.7692
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
When dividing 40 by 13, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 5984901.76923
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 5984901.76923
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 15:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 5984901.7692307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 16:
When dividing 90 by 13, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 5984901.76923076
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 5984901.76923076, with a leftover of 1.2e-08.
