66714164 ÷ 917 
We want to figure out the number of times 66714164 can be divided by 917.

Moving on to step 1:
917 goes into 6 0 times with 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.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 917

Advancing to step 2:
When dividing 66 by 917, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 917

Advancing to step 3:
917 can be fit into 667 0 times, resulting in a remainder of 667.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 667 and we're left with 667.
Append the next digit (1) from the dividend to 667 and continue with: 6671 / 917

On to step 4:
The number 917 fits into 6671 7 times, leaving a remainder of 252.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 6419 from 6671 leaves us with 252.
Append the next digit (4) from the dividend to 252 and continue with: 2524 / 917

On to step 5:
The number 917 fits into 2524 2 times, leaving a remainder of 690.
The next digit of our result is 2. 
Result so far: 72.0
Subtract 1834 from 2524 to get 690.
Include the next digit (1) from the dividend after 690, then repeat: 6901 / 917

Let's proceed to step 6:
917 can be fit into 6901 7 times, resulting in a remainder of 482.
Use 7 as the next digit of our solution. 
Result so far: 727.0
If we take 6419 away from 6901, we end up with 482.
Append the next digit (6) from the dividend to 482 and continue with: 4826 / 917

Going ahead to step 7:
917 can be fit into 4826 5 times, resulting in a remainder of 241.
Write down 5 as next digit of the result. 
Result so far: 7275.0
If we take 4585 away from 4826, we end up with 241.
Append the next digit (4) from the dividend to 241 and continue with: 2414 / 917

Moving on to step 8:
If we divide 2414 by 917, we get 2 and a remainder of 580.
Record the quotient 2 as the next digit in the result. 
Result so far: 72752.0
Subtracting 1834 from 2414 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 9:
917 can be fit into 5800 6 times, resulting in a remainder of 298.
Write down 6 as next digit of the result. 
Result so far: 72752.6
If we subtract 5502 from 5800, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 10:
When dividing 2980 by 917, we get 3 with a remainder of 229.
Use 3 as the next digit of our solution. 
Result so far: 72752.63
Subtract 2751 from 2980 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Advancing to step 11:
If we divide 2290 by 917, we get 2 and a remainder of 456.
The next digit of our result is 2. 
Result so far: 72752.632
If we subtract 1834 from 2290, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 12:
When dividing 4560 by 917, we get 4 with a remainder of 892.
The number 4 becomes the next digit in our result. 
Result so far: 72752.6324
If we take 3668 away from 4560, we end up with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

On to step 13:
The number 917 fits into 8920 9 times, leaving a remainder of 667.
The number 9 becomes the next digit in our result. 
Result so far: 72752.63249
Subtracting 8253 from 8920 leaves us with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Advancing to step 14:
When dividing 6670 by 917, we get 7 with a remainder of 251.
The next digit of our result is 7. 
Result so far: 72752.632497
Deduct 6419 from 6670 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 15:
917 goes into 2510 2 times with a remainder of 676.
The next digit of our result is 2. 
Result so far: 72752.6324972
Deduct 1834 from 2510 and we're left with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Advancing to step 16:
6760 divided by 917 is 7 with a remainder of 341.
Record the quotient 7 as the next digit in the result. 
Result so far: 72752.63249727
Deduct 6419 from 6760 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

The final outcome is 72752.63249727, with a leftover of 3.41e-07.
