66251024 ÷ 945 
Let's see how many times 945 fits into 66251024.

Going ahead to step 1:
When dividing 6 by 945, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 945

Let's proceed to step 2:
If we divide 66 by 945, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (2) from the dividend, add it to 66, then carry on: 662 / 945

Let's proceed to step 3:
945 goes into 662 0 times with a remainder of 662.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 662 and we're left with 662.
Bring next digit (5) of the dividend behind the 662 and repeat the process: 6625 / 945

Advancing to step 4:
The number 945 fits into 6625 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 6615 from 6625 to get 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 945

Let's proceed to step 5:
If we divide 101 by 945, we get 0 and a remainder of 101.
Write down 0 as next digit of the result. 
Result so far: 70.0
The remainder is 101 after subtracting 0 from 101.
Include the next digit (0) from the dividend after 101, then repeat: 1010 / 945

On to step 6:
1010 divided by 945 is 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 701.0
If we subtract 945 from 1010, we get 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 945

Advancing to step 7:
652 divided by 945 is 0 with a remainder of 652.
Write down 0 as next digit of the result. 
Result so far: 7010.0
Deduct 0 from 652 and we're left with 652.
Bring next digit (4) of the dividend behind the 652 and repeat the process: 6524 / 945

Advancing to step 8:
6524 divided by 945 is 6 with a remainder of 854.
The next digit of our result is 6. 
Result so far: 70106.0
Deduct 5670 from 6524 and we're left with 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Step 9:
945 goes into 8540 9 times with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 70106.9
If we subtract 8505 from 8540, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
945 can be fit into 350 0 times, resulting in a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 70106.9
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 11:
If we divide 3500 by 945, we get 3 and a remainder of 665.
Record the quotient 3 as the next digit in the result. 
Result so far: 70106.903
Subtract 2835 from 3500 to get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Going ahead to step 12:
945 goes into 6650 7 times with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 70106.9037
The remainder is 35 after subtracting 6615 from 6650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
945 goes into 350 0 times with a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 70106.9037
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 14:
When dividing 3500 by 945, we get 3 with a remainder of 665.
The next digit of our result is 3. 
Result so far: 70106.903703
Subtract 2835 from 3500 to get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Moving on to step 15:
The number 945 fits into 6650 7 times, leaving a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 70106.9037037
Deduct 6615 from 6650 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 16:
945 goes into 350 0 times with a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 70106.9037037
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

In conclusion, the division gives 70106.9037037 with a balance of 3.5e-07.
