Let's divide 838453 by 78
We want to figure out the number of times 838453 can be divided by 78.

Step 1:
8 divided by 78 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 78

Step 2:
78 can be fit into 83 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
If we take 78 away from 83, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 78

Let's proceed to step 3:
58 divided by 78 is 0 with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 58, we get 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 78

Let's proceed to step 4:
When dividing 584 by 78, we get 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we take 546 away from 584, we end up with 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 78

Step 5:
The number 78 fits into 385 4 times, leaving a remainder of 73.
Use 4 as the next digit of our solution. 
Result so far: 1074.0
If we subtract 312 from 385, we get 73.
Bring next digit (3) of the dividend behind the 73 and repeat the process: 733 / 78

On to step 6:
If we divide 733 by 78, we get 9 and a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 10749.0
The remainder is 31 after subtracting 702 from 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
78 goes into 310 3 times with a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 10749.3
Subtracting 234 from 310 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 8:
When dividing 760 by 78, we get 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 10749.39
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 10749.397
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
78 goes into 340 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 10749.3974
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 10749.39743
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
460 divided by 78 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 10749.397435
If we subtract 390 from 460, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 13:
If we divide 700 by 78, we get 8 and a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 10749.3974358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
760 divided by 78 is 9 with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 10749.39743589
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 10749.39743589 with a remaining 5.8e-08.
