66817360 ÷ 957 
We want to figure out the number of times 66817360 can be divided by 957.

Going ahead to step 1:
If we divide 6 by 957, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 957

Advancing to step 2:
66 divided by 957 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.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 957

Step 3:
If we divide 668 by 957, we get 0 and a remainder of 668.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 668, we get 668.
Take the next digit (1) from the dividend and append it to 668, then repeat: 6681 / 957

Let's proceed to step 4:
When dividing 6681 by 957, we get 6 with a remainder of 939.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 5742 away from 6681, we end up with 939.
Take the next digit (7) from the dividend and append it to 939, then repeat: 9397 / 957

Moving on to step 5:
957 can be fit into 9397 9 times, resulting in a remainder of 784.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Deduct 8613 from 9397 and we're left with 784.
Fetch the next digit (3) from the dividend, attach it to 784 and continue: 7843 / 957

Let's proceed to step 6:
The number 957 fits into 7843 8 times, leaving a remainder of 187.
Put 8 as the next digit of the answer. 
Result so far: 698.0
Subtracting 7656 from 7843 leaves us with 187.
Grab the next digit (6) from the dividend, add it to 187, then carry on: 1876 / 957

Going ahead to step 7:
If we divide 1876 by 957, we get 1 and a remainder of 919.
Use 1 as the next digit of our solution. 
Result so far: 6981.0
If we take 957 away from 1876, we end up with 919.
Include the next digit (0) from the dividend after 919, then repeat: 9190 / 957

On to step 8:
If we divide 9190 by 957, we get 9 and a remainder of 577.
Put 9 as the next digit of the answer. 
Result so far: 69819.0
If we take 8613 away from 9190, we end up with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Let's proceed to step 9:
957 goes into 5770 6 times with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 69819.6
Subtract 5742 from 5770 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
If we divide 280 by 957, we get 0 and a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 69819.6
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 11:
957 can be fit into 2800 2 times, resulting in a remainder of 886.
The number 2 becomes the next digit in our result. 
Result so far: 69819.602
Deduct 1914 from 2800 and we're left with 886.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8860, and continue the process.

Step 12:
8860 divided by 957 is 9 with a remainder of 247.
Write down 9 as next digit of the result. 
Result so far: 69819.6029
If we take 8613 away from 8860, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 13:
If we divide 2470 by 957, we get 2 and a remainder of 556.
Use 2 as the next digit of our solution. 
Result so far: 69819.60292
Subtracting 1914 from 2470 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 14:
The number 957 fits into 5560 5 times, leaving a remainder of 775.
Use 5 as the next digit of our solution. 
Result so far: 69819.602925
If we take 4785 away from 5560, we end up with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Step 15:
7750 divided by 957 is 8 with a remainder of 94.
Record the quotient 8 as the next digit in the result. 
Result so far: 69819.6029258
If we subtract 7656 from 7750, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 16:
940 divided by 957 is 0 with a remainder of 940.
The number 0 becomes the next digit in our result. 
Result so far: 69819.6029258
Subtract 0 from 940 to get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Our division results in 69819.6029258 with a remaining 9.4e-07.
