Let's divide 854521 by 78
We want to figure out the number of times 854521 can be divided by 78.

Let's proceed to 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
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 78

Moving on to step 2:
The number 78 fits into 85 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 78 from 85 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 78

Going ahead to step 3:
The number 78 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 74 after subtracting 0 from 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 78

Moving on to step 4:
745 divided by 78 is 9 with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 109.0
The remainder is 43 after subtracting 702 from 745.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 78

On to step 5:
When dividing 432 by 78, we get 5 with a remainder of 42.
The number 5 becomes the next digit in our result. 
Result so far: 1095.0
If we take 390 away from 432, we end up with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 78

Going ahead to step 6:
The number 78 fits into 421 5 times, leaving a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 10955.0
If we subtract 390 from 421, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
If we divide 310 by 78, we get 3 and a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 10955.3
Subtract 234 from 310 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 8:
If we divide 760 by 78, we get 9 and a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 10955.39
Deduct 702 from 760 and we're left 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.

Let's proceed to step 9:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 10955.397
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.

On to step 10:
340 divided by 78 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 10955.3974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
280 divided by 78 is 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 10955.39743
If we subtract 234 from 280, we get 46.
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:
When dividing 460 by 78, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 10955.397435
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.

On to step 13:
When dividing 700 by 78, we get 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 10955.3974358
Subtracting 624 from 700 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.

Moving on to step 14:
When dividing 760 by 78, we get 9 with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 10955.39743589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

In conclusion, the division gives 10955.39743589 with a balance of 5.8e-08.
