Let's divide 858658 by 78
Our goal is to divide 858658 by 78.

Advancing 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
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 78

Moving on to step 2:
78 can be fit into 85 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 7 after subtracting 78 from 85.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 78

Step 3:
78 can be fit into 78 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 78 from 78 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 78

Let's proceed to step 4:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 110.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 78

Advancing to step 5:
78 can be fit into 65 0 times, resulting in a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 1100.0
The remainder is 65 after subtracting 0 from 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 78

Let's proceed to step 6:
658 divided by 78 is 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 11008.0
Subtract 624 from 658 to get 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 7:
78 goes into 340 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 11008.4
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.

Going ahead to step 8:
280 divided by 78 is 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 11008.43
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 9:
When dividing 460 by 78, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 11008.435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
If we divide 700 by 78, we get 8 and a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 11008.4358
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.

Advancing to step 11:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 11008.43589
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
If we divide 580 by 78, we get 7 and a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 11008.435897
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
If we divide 340 by 78, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 11008.4358974
If we take 312 away from 340, we end up 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 14:
78 can be fit into 280 3 times, resulting in a remainder of 46.
The next digit of our result is 3. 
Result so far: 11008.43589743
Subtracting 234 from 280 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 11008.43589743 and a remainder of 4.6e-08.
