We're dividing 849940 by 78 
We're looking to find how many times 78 goes into 849940.

Moving on to step 1:
78 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 78

Advancing to step 2:
78 can be fit into 84 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 78 from 84 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 78

Step 3:
If we divide 69 by 78, we get 0 and a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 69 after subtracting 0 from 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 78

Moving on to step 4:
78 goes into 699 8 times with a remainder of 75.
The next digit of our result is 8. 
Result so far: 108.0
If we take 624 away from 699, we end up with 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 78

Moving on to step 5:
If we divide 754 by 78, we get 9 and a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 1089.0
If we take 702 away from 754, we end up with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 78

On to step 6:
78 goes into 520 6 times with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 10896.0
Subtract 468 from 520 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
78 can be fit into 520 6 times, resulting in a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 10896.6
Subtracting 468 from 520 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
The number 78 fits into 520 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 10896.66
If we take 468 away from 520, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 10896.66 and a remainder of 0.052.
