Let's divide 850991 by 66
Let's see how many times 66 fits into 850991.

On to step 1:
When dividing 8 by 66, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 66

Advancing to step 2:
85 divided by 66 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 19 after subtracting 66 from 85.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 66

Advancing to step 3:
When dividing 190 by 66, we get 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 132 from 190 to get 58.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 66

Moving on to step 4:
66 goes into 589 8 times with a remainder of 61.
The next digit of our result is 8. 
Result so far: 128.0
If we take 528 away from 589, we end up with 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 66

Let's proceed to step 5:
When dividing 619 by 66, we get 9 with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 1289.0
If we take 594 away from 619, we end up with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 66

On to step 6:
When dividing 251 by 66, we get 3 with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 12893.0
If we subtract 198 from 251, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
66 can be fit into 530 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 12893.8
Subtract 528 from 530 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 66 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 12893.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 12893.803
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
If we divide 20 by 66, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 12893.803
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
If we divide 200 by 66, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 12893.80303
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
66 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12893.80303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
If we divide 200 by 66, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 12893.8030303
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12893.8030303
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 12893.8030303 with a remaining 2e-08.
