We're dividing 80858520 by 966 
We're looking to find how many times 966 goes into 80858520.

Step 1:
966 goes into 8 0 times with 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 (0) from the dividend, add it to 8, then carry on: 80 / 966

Let's proceed to step 2:
If we divide 80 by 966, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 966

On to step 3:
966 can be fit into 808 0 times, resulting in a remainder of 808.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 808, we end up with 808.
Take the next digit (5) from the dividend and append it to 808, then repeat: 8085 / 966

Let's proceed to step 4:
The number 966 fits into 8085 8 times, leaving a remainder of 357.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 7728 from 8085 and we're left with 357.
Append the next digit (8) from the dividend to 357 and continue with: 3578 / 966

Let's proceed to step 5:
966 can be fit into 3578 3 times, resulting in a remainder of 680.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we subtract 2898 from 3578, we get 680.
Bring next digit (5) of the dividend behind the 680 and repeat the process: 6805 / 966

Let's proceed to step 6:
6805 divided by 966 is 7 with a remainder of 43.
The next digit of our result is 7. 
Result so far: 837.0
Subtracting 6762 from 6805 leaves us with 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 966

Let's proceed to step 7:
432 divided by 966 is 0 with a remainder of 432.
Write down 0 as next digit of the result. 
Result so far: 8370.0
Subtracting 0 from 432 leaves us with 432.
Grab the next digit (0) from the dividend, add it to 432, then carry on: 4320 / 966

Advancing to step 8:
966 can be fit into 4320 4 times, resulting in a remainder of 456.
Use 4 as the next digit of our solution. 
Result so far: 83704.0
Subtracting 3864 from 4320 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 9:
966 can be fit into 4560 4 times, resulting in a remainder of 696.
The number 4 becomes the next digit in our result. 
Result so far: 83704.4
Subtract 3864 from 4560 to get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Moving on to step 10:
The number 966 fits into 6960 7 times, leaving a remainder of 198.
Put 7 as the next digit of the answer. 
Result so far: 83704.47
If we subtract 6762 from 6960, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 11:
If we divide 1980 by 966, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 83704.472
The remainder is 48 after subtracting 1932 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
966 can be fit into 480 0 times, resulting in a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 83704.472
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
966 can be fit into 4800 4 times, resulting in a remainder of 936.
Put 4 as the next digit of the answer. 
Result so far: 83704.47204
If we subtract 3864 from 4800, we get 936.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9360, and continue the process.

Advancing to step 14:
When dividing 9360 by 966, we get 9 with a remainder of 666.
Record the quotient 9 as the next digit in the result. 
Result so far: 83704.472049
Subtracting 8694 from 9360 leaves us with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Let's proceed to step 15:
966 goes into 6660 6 times with a remainder of 864.
Put 6 as the next digit of the answer. 
Result so far: 83704.4720496
Subtract 5796 from 6660 to get 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Going ahead to step 16:
8640 divided by 966 is 8 with a remainder of 912.
Put 8 as the next digit of the answer. 
Result so far: 83704.47204968
If we subtract 7728 from 8640, we get 912.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9120, and continue the process.

In conclusion, the division gives 83704.47204968 with a balance of 9.12e-07.
