64115554 divided by 960 
We want to figure out the number of times 64115554 can be divided by 960.

On to step 1:
When dividing 6 by 960, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 960

Moving on to step 2:
When dividing 64 by 960, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 960

On to step 3:
641 divided by 960 is 0 with a remainder of 641.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 641 leaves us with 641.
Fetch the next digit (1) from the dividend, attach it to 641 and continue: 6411 / 960

On to step 4:
960 goes into 6411 6 times with a remainder of 651.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 5760 from 6411 and we're left with 651.
Fetch the next digit (5) from the dividend, attach it to 651 and continue: 6515 / 960

Let's proceed to step 5:
If we divide 6515 by 960, we get 6 and a remainder of 755.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Deduct 5760 from 6515 and we're left with 755.
Bring next digit (5) of the dividend behind the 755 and repeat the process: 7555 / 960

Advancing to step 6:
The number 960 fits into 7555 7 times, leaving a remainder of 835.
Use 7 as the next digit of our solution. 
Result so far: 667.0
If we take 6720 away from 7555, we end up with 835.
Bring next digit (5) of the dividend behind the 835 and repeat the process: 8355 / 960

Going ahead to step 7:
If we divide 8355 by 960, we get 8 and a remainder of 675.
Write down 8 as next digit of the result. 
Result so far: 6678.0
Deduct 7680 from 8355 and we're left with 675.
Grab the next digit (4) from the dividend, add it to 675, then carry on: 6754 / 960

Moving on to step 8:
If we divide 6754 by 960, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 66787.0
The remainder is 34 after subtracting 6720 from 6754.
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 9:
960 can be fit into 340 0 times, resulting in a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 66787.0
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 10:
When dividing 3400 by 960, we get 3 with a remainder of 520.
Put 3 as the next digit of the answer. 
Result so far: 66787.03
Subtract 2880 from 3400 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 11:
5200 divided by 960 is 5 with a remainder of 400.
The next digit of our result is 5. 
Result so far: 66787.035
The remainder is 400 after subtracting 4800 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
When dividing 4000 by 960, we get 4 with a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 66787.0354
The remainder is 160 after subtracting 3840 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 13:
1600 divided by 960 is 1 with a remainder of 640.
Use 1 as the next digit of our solution. 
Result so far: 66787.03541
The remainder is 640 after subtracting 960 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 14:
960 goes into 6400 6 times with a remainder of 640.
Put 6 as the next digit of the answer. 
Result so far: 66787.035416
Subtracting 5760 from 6400 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 15:
The number 960 fits into 6400 6 times, leaving a remainder of 640.
Record the quotient 6 as the next digit in the result. 
Result so far: 66787.0354166
The remainder is 640 after subtracting 5760 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

In conclusion, the division gives 66787.0354166 with a balance of 6.4e-06.
