66330942 ÷ 945 
We want to figure out the number of times 66330942 can be divided by 945.

Advancing to step 1:
When dividing 6 by 945, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 945

Advancing to step 2:
When dividing 66 by 945, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 945

Advancing to step 3:
The number 945 fits into 663 0 times, leaving a remainder of 663.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 663 after subtracting 0 from 663.
Include the next digit (3) from the dividend after 663, then repeat: 6633 / 945

Step 4:
When dividing 6633 by 945, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 6615 from 6633 leaves us with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 945

Moving on to step 5:
If we divide 180 by 945, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Subtracting 0 from 180 leaves us with 180.
Bring next digit (9) of the dividend behind the 180 and repeat the process: 1809 / 945

Step 6:
945 can be fit into 1809 1 times, resulting in a remainder of 864.
Put 1 as the next digit of the answer. 
Result so far: 701.0
Deduct 945 from 1809 and we're left with 864.
Include the next digit (4) from the dividend after 864, then repeat: 8644 / 945

Step 7:
945 can be fit into 8644 9 times, resulting in a remainder of 139.
Put 9 as the next digit of the answer. 
Result so far: 7019.0
The remainder is 139 after subtracting 8505 from 8644.
Fetch the next digit (2) from the dividend, attach it to 139 and continue: 1392 / 945

Step 8:
1392 divided by 945 is 1 with a remainder of 447.
Record the quotient 1 as the next digit in the result. 
Result so far: 70191.0
The remainder is 447 after subtracting 945 from 1392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Going ahead to step 9:
4470 divided by 945 is 4 with a remainder of 690.
Record the quotient 4 as the next digit in the result. 
Result so far: 70191.4
If we take 3780 away from 4470, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 10:
If we divide 6900 by 945, we get 7 and a remainder of 285.
Use 7 as the next digit of our solution. 
Result so far: 70191.47
Subtract 6615 from 6900 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 11:
When dividing 2850 by 945, we get 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 70191.473
The remainder is 15 after subtracting 2835 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
150 divided by 945 is 0 with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 70191.473
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 13:
1500 divided by 945 is 1 with a remainder of 555.
The next digit of our result is 1. 
Result so far: 70191.47301
If we subtract 945 from 1500, we get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Let's proceed to step 14:
The number 945 fits into 5550 5 times, leaving a remainder of 825.
The next digit of our result is 5. 
Result so far: 70191.473015
Subtracting 4725 from 5550 leaves us with 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

Step 15:
If we divide 8250 by 945, we get 8 and a remainder of 690.
The number 8 becomes the next digit in our result. 
Result so far: 70191.4730158
Deduct 7560 from 8250 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 16:
945 goes into 6900 7 times with a remainder of 285.
The next digit of our result is 7. 
Result so far: 70191.47301587
Subtracting 6615 from 6900 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Our division results in 70191.47301587 with a remaining 2.85e-07.
