We're dividing 84378176 by 660 
We're looking to find how many times 660 goes into 84378176.

Going ahead to step 1:
If we divide 8 by 660, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 660

Advancing to step 2:
84 divided by 660 is 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Grab the next digit (3) from the dividend, add it to 84, then carry on: 843 / 660

Going ahead to step 3:
The number 660 fits into 843 1 times, leaving a remainder of 183.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 660 from 843 to get 183.
Fetch the next digit (7) from the dividend, attach it to 183 and continue: 1837 / 660

Let's proceed to step 4:
1837 divided by 660 is 2 with a remainder of 517.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1320 from 1837 leaves us with 517.
Bring next digit (8) of the dividend behind the 517 and repeat the process: 5178 / 660

On to step 5:
When dividing 5178 by 660, we get 7 with a remainder of 558.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
If we take 4620 away from 5178, we end up with 558.
Take the next digit (1) from the dividend and append it to 558, then repeat: 5581 / 660

Step 6:
660 goes into 5581 8 times with a remainder of 301.
Write down 8 as next digit of the result. 
Result so far: 1278.0
Subtract 5280 from 5581 to get 301.
Fetch the next digit (7) from the dividend, attach it to 301 and continue: 3017 / 660

Step 7:
3017 divided by 660 is 4 with a remainder of 377.
Write down 4 as next digit of the result. 
Result so far: 12784.0
Subtracting 2640 from 3017 leaves us with 377.
Grab the next digit (6) from the dividend, add it to 377, then carry on: 3776 / 660

Moving on to step 8:
3776 divided by 660 is 5 with a remainder of 476.
Write down 5 as next digit of the result. 
Result so far: 127845.0
If we take 3300 away from 3776, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Advancing to step 9:
If we divide 4760 by 660, we get 7 and a remainder of 140.
Record the quotient 7 as the next digit in the result. 
Result so far: 127845.7
If we subtract 4620 from 4760, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
When dividing 1400 by 660, we get 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 127845.72
If we take 1320 away from 1400, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
If we divide 800 by 660, we get 1 and a remainder of 140.
Record the quotient 1 as the next digit in the result. 
Result so far: 127845.721
Deduct 660 from 800 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 12:
660 can be fit into 1400 2 times, resulting in a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 127845.7212
If we subtract 1320 from 1400, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
If we divide 800 by 660, we get 1 and a remainder of 140.
The number 1 becomes the next digit in our result. 
Result so far: 127845.72121
If we take 660 away from 800, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 14:
The number 660 fits into 1400 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 127845.721212
Subtracting 1320 from 1400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 15:
660 can be fit into 800 1 times, resulting in a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 127845.7212121
Subtract 660 from 800 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 16:
660 goes into 1400 2 times with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 127845.72121212
The remainder is 80 after subtracting 1320 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 127845.72121212 with a balance of 8e-08.
