64302834 divided by 660 
Our goal is to divide 64302834 by 660.

On to step 1:
660 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 660

Let's proceed to step 2:
64 divided by 660 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 660

Going ahead to step 3:
660 can be fit into 643 0 times, resulting in a remainder of 643.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 643 and we're left with 643.
Bring next digit (0) of the dividend behind the 643 and repeat the process: 6430 / 660

Moving on to step 4:
When dividing 6430 by 660, we get 9 with a remainder of 490.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 5940 from 6430 and we're left with 490.
Take the next digit (2) from the dividend and append it to 490, then repeat: 4902 / 660

Advancing to step 5:
4902 divided by 660 is 7 with a remainder of 282.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtracting 4620 from 4902 leaves us with 282.
Append the next digit (8) from the dividend to 282 and continue with: 2828 / 660

On to step 6:
If we divide 2828 by 660, we get 4 and a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 974.0
The remainder is 188 after subtracting 2640 from 2828.
Bring next digit (3) of the dividend behind the 188 and repeat the process: 1883 / 660

Advancing to step 7:
660 can be fit into 1883 2 times, resulting in a remainder of 563.
Use 2 as the next digit of our solution. 
Result so far: 9742.0
If we take 1320 away from 1883, we end up with 563.
Bring next digit (4) of the dividend behind the 563 and repeat the process: 5634 / 660

Let's proceed to step 8:
The number 660 fits into 5634 8 times, leaving a remainder of 354.
Record the quotient 8 as the next digit in the result. 
Result so far: 97428.0
If we subtract 5280 from 5634, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 9:
660 goes into 3540 5 times with a remainder of 240.
Put 5 as the next digit of the answer. 
Result so far: 97428.5
If we subtract 3300 from 3540, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
The number 660 fits into 2400 3 times, leaving a remainder of 420.
The next digit of our result is 3. 
Result so far: 97428.53
Subtract 1980 from 2400 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
If we divide 4200 by 660, we get 6 and a remainder of 240.
Record the quotient 6 as the next digit in the result. 
Result so far: 97428.536
Subtracting 3960 from 4200 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
660 can be fit into 2400 3 times, resulting in a remainder of 420.
The next digit of our result is 3. 
Result so far: 97428.5363
Subtracting 1980 from 2400 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 13:
660 can be fit into 4200 6 times, resulting in a remainder of 240.
Write down 6 as next digit of the result. 
Result so far: 97428.53636
Subtracting 3960 from 4200 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
When dividing 2400 by 660, we get 3 with a remainder of 420.
The number 3 becomes the next digit in our result. 
Result so far: 97428.536363
The remainder is 420 after subtracting 1980 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 15:
The number 660 fits into 4200 6 times, leaving a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 97428.5363636
If we subtract 3960 from 4200, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 16:
The number 660 fits into 2400 3 times, leaving a remainder of 420.
Record the quotient 3 as the next digit in the result. 
Result so far: 97428.53636363
If we subtract 1980 from 2400, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

In conclusion, the division gives 97428.53636363 with a balance of 4.2e-07.
