66235866 divided by 946 
We want to figure out the number of times 66235866 can be divided by 946.

Going ahead to step 1:
946 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 946

Let's proceed to step 2:
66 divided by 946 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 946

Advancing to step 3:
When dividing 662 by 946, we get 0 with a remainder of 662.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 662 after subtracting 0 from 662.
Grab the next digit (3) from the dividend, add it to 662, then carry on: 6623 / 946

On to step 4:
6623 divided by 946 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 6622 from 6623 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 946

Moving on to step 5:
946 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we subtract 0 from 15, we get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 946

Moving on to step 6:
If we divide 158 by 946, we get 0 and a remainder of 158.
Write down 0 as next digit of the result. 
Result so far: 700.0
Subtract 0 from 158 to get 158.
Bring next digit (6) of the dividend behind the 158 and repeat the process: 1586 / 946

Step 7:
946 can be fit into 1586 1 times, resulting in a remainder of 640.
Put 1 as the next digit of the answer. 
Result so far: 7001.0
Subtracting 946 from 1586 leaves us with 640.
Take the next digit (6) from the dividend and append it to 640, then repeat: 6406 / 946

On to step 8:
The number 946 fits into 6406 6 times, leaving a remainder of 730.
The number 6 becomes the next digit in our result. 
Result so far: 70016.0
Subtract 5676 from 6406 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 9:
7300 divided by 946 is 7 with a remainder of 678.
The next digit of our result is 7. 
Result so far: 70016.7
If we subtract 6622 from 7300, we get 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Let's proceed to step 10:
6780 divided by 946 is 7 with a remainder of 158.
The number 7 becomes the next digit in our result. 
Result so far: 70016.77
If we take 6622 away from 6780, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

After the division, we end up with 70016.77 and a remainder of 0.158.
