We look at the division of 78999997 by 87 
We're looking to find how many times 87 goes into 78999997.

Moving on to step 1:
87 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 87

Step 2:
87 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 87

On to step 3:
The number 87 fits into 789 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 783 from 789 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 87

Let's proceed to step 4:
If we divide 69 by 87, we get 0 and a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Subtract 0 from 69 to get 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 87

Moving on to step 5:
When dividing 699 by 87, we get 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 908.0
Deduct 696 from 699 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 87

Advancing to step 6:
If we divide 39 by 87, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 9080.0
If we take 0 away from 39, we end up with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 87

Advancing to step 7:
399 divided by 87 is 4 with a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 90804.0
If we take 348 away from 399, we end up with 51.
Append the next digit (7) from the dividend to 51 and continue with: 517 / 87

Advancing to step 8:
The number 87 fits into 517 5 times, leaving a remainder of 82.
Put 5 as the next digit of the answer. 
Result so far: 908045.0
Subtract 435 from 517 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 9:
When dividing 820 by 87, we get 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 908045.9
Subtract 783 from 820 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
87 goes into 370 4 times with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 908045.94
If we take 348 away from 370, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
87 can be fit into 220 2 times, resulting in a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 908045.942
If we take 174 away from 220, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
If we divide 460 by 87, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 908045.9425
If we subtract 435 from 460, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
When dividing 250 by 87, we get 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 908045.94252
If we subtract 174 from 250, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
The number 87 fits into 760 8 times, leaving a remainder of 64.
The next digit of our result is 8. 
Result so far: 908045.942528
If we subtract 696 from 760, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
640 divided by 87 is 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 908045.9425287
Subtract 609 from 640 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 16:
87 can be fit into 310 3 times, resulting in a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 908045.94252873
Subtracting 261 from 310 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The quotient of the division is 908045.94252873, and the remainder is 4.9e-08.
