71660027 ÷ 79 
We want to figure out the number of times 71660027 can be divided by 79.

On to step 1:
79 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 79

Step 2:
79 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 79

Moving on to step 3:
79 can be fit into 716 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 711 from 716 and we're left with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 79

Step 4:
The number 79 fits into 56 0 times, leaving a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtract 0 from 56 to get 56.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 79

Advancing to step 5:
560 divided by 79 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 907.0
Subtract 553 from 560 to get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 79

Going ahead to step 6:
79 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 9070.0
Subtracting 0 from 70 leaves us with 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 79

Let's proceed to step 7:
If we divide 702 by 79, we get 8 and a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 90708.0
If we take 632 away from 702, we end up with 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 79

Advancing to step 8:
The number 79 fits into 707 8 times, leaving a remainder of 75.
Use 8 as the next digit of our solution. 
Result so far: 907088.0
If we take 632 away from 707, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
When dividing 750 by 79, we get 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 907088.9
If we take 711 away from 750, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
79 can be fit into 390 4 times, resulting in a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 907088.94
If we subtract 316 from 390, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
740 divided by 79 is 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 907088.949
The remainder is 29 after subtracting 711 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
79 goes into 290 3 times with a remainder of 53.
The next digit of our result is 3. 
Result so far: 907088.9493
Subtract 237 from 290 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 13:
79 can be fit into 530 6 times, resulting in a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 907088.94936
The remainder is 56 after subtracting 474 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 14:
The number 79 fits into 560 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 907088.949367
Subtracting 553 from 560 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 15:
If we divide 70 by 79, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 907088.949367
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 16:
If we divide 700 by 79, we get 8 and a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 907088.94936708
If we take 632 away from 700, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 907088.94936708, with a leftover of 6.8e-08.
