87663865 divided by 960 
We want to figure out the number of times 87663865 can be divided by 960.

Moving on to step 1:
960 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 960

Let's proceed to step 2:
87 divided by 960 is 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Take the next digit (6) from the dividend and append it to 87, then repeat: 876 / 960

Advancing to step 3:
The number 960 fits into 876 0 times, leaving a remainder of 876.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 876 and we're left with 876.
Take the next digit (6) from the dividend and append it to 876, then repeat: 8766 / 960

Going ahead to step 4:
8766 divided by 960 is 9 with a remainder of 126.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 8640 away from 8766, we end up with 126.
Fetch the next digit (3) from the dividend, attach it to 126 and continue: 1263 / 960

Let's proceed to step 5:
If we divide 1263 by 960, we get 1 and a remainder of 303.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Deduct 960 from 1263 and we're left with 303.
Append the next digit (8) from the dividend to 303 and continue with: 3038 / 960

Step 6:
The number 960 fits into 3038 3 times, leaving a remainder of 158.
The next digit of our result is 3. 
Result so far: 913.0
Subtract 2880 from 3038 to get 158.
Append the next digit (6) from the dividend to 158 and continue with: 1586 / 960

On to step 7:
When dividing 1586 by 960, we get 1 with a remainder of 626.
Put 1 as the next digit of the answer. 
Result so far: 9131.0
Subtract 960 from 1586 to get 626.
Append the next digit (5) from the dividend to 626 and continue with: 6265 / 960

Going ahead to step 8:
If we divide 6265 by 960, we get 6 and a remainder of 505.
The number 6 becomes the next digit in our result. 
Result so far: 91316.0
If we subtract 5760 from 6265, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 9:
If we divide 5050 by 960, we get 5 and a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 91316.5
Subtracting 4800 from 5050 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
When dividing 2500 by 960, we get 2 with a remainder of 580.
Put 2 as the next digit of the answer. 
Result so far: 91316.52
If we subtract 1920 from 2500, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 11:
The number 960 fits into 5800 6 times, leaving a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 91316.526
If we subtract 5760 from 5800, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 960, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 91316.526
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 13:
The number 960 fits into 4000 4 times, leaving a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 91316.52604
If we take 3840 away from 4000, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
1600 divided by 960 is 1 with a remainder of 640.
The next digit of our result is 1. 
Result so far: 91316.526041
Subtract 960 from 1600 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 15:
960 goes into 6400 6 times with a remainder of 640.
Write down 6 as next digit of the result. 
Result so far: 91316.5260416
If we subtract 5760 from 6400, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 16:
960 goes into 6400 6 times with a remainder of 640.
The number 6 becomes the next digit in our result. 
Result so far: 91316.52604166
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.

Our division results in 91316.52604166 with a remaining 6.4e-07.
