We're dividing 66660439 by 848 
We want to divide 66660439 by 848.

Going ahead to step 1:
848 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 848

Going ahead to step 2:
848 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 848

On to step 3:
666 divided by 848 is 0 with a remainder of 666.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 666 leaves us with 666.
Append the next digit (6) from the dividend to 666 and continue with: 6666 / 848

Step 4:
6666 divided by 848 is 7 with a remainder of 730.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 5936 away from 6666, we end up with 730.
Append the next digit (0) from the dividend to 730 and continue with: 7300 / 848

Going ahead to step 5:
When dividing 7300 by 848, we get 8 with a remainder of 516.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 6784 from 7300 and we're left with 516.
Append the next digit (4) from the dividend to 516 and continue with: 5164 / 848

Let's proceed to step 6:
The number 848 fits into 5164 6 times, leaving a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 786.0
Deduct 5088 from 5164 and we're left with 76.
Grab the next digit (3) from the dividend, add it to 76, then carry on: 763 / 848

Moving on to step 7:
848 can be fit into 763 0 times, resulting in a remainder of 763.
Record the quotient 0 as the next digit in the result. 
Result so far: 7860.0
Subtracting 0 from 763 leaves us with 763.
Include the next digit (9) from the dividend after 763, then repeat: 7639 / 848

On to step 8:
If we divide 7639 by 848, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 78609.0
If we subtract 7632 from 7639, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
848 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 78609.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
848 can be fit into 700 0 times, resulting in a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 78609.0
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The quotient of the division is 78609.0, and the remainder is 0.7.
