78635564 ÷ 879 
Let's see how many times 879 fits into 78635564.

Advancing to step 1:
The number 879 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 879

Going ahead to step 2:
879 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
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 879

On to step 3:
When dividing 786 by 879, we get 0 with a remainder of 786.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 786, we end up with 786.
Fetch the next digit (3) from the dividend, attach it to 786 and continue: 7863 / 879

Let's proceed to step 4:
When dividing 7863 by 879, we get 8 with a remainder of 831.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 7032 from 7863 leaves us with 831.
Fetch the next digit (5) from the dividend, attach it to 831 and continue: 8315 / 879

Moving on to step 5:
If we divide 8315 by 879, we get 9 and a remainder of 404.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we subtract 7911 from 8315, we get 404.
Grab the next digit (5) from the dividend, add it to 404, then carry on: 4045 / 879

Advancing to step 6:
879 can be fit into 4045 4 times, resulting in a remainder of 529.
Put 4 as the next digit of the answer. 
Result so far: 894.0
Subtract 3516 from 4045 to get 529.
Bring next digit (6) of the dividend behind the 529 and repeat the process: 5296 / 879

Advancing to step 7:
879 goes into 5296 6 times with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 8946.0
The remainder is 22 after subtracting 5274 from 5296.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 879

Let's proceed to step 8:
When dividing 224 by 879, we get 0 with a remainder of 224.
The number 0 becomes the next digit in our result. 
Result so far: 89460.0
If we take 0 away from 224, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 9:
2240 divided by 879 is 2 with a remainder of 482.
Put 2 as the next digit of the answer. 
Result so far: 89460.2
Subtract 1758 from 2240 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Moving on to step 10:
4820 divided by 879 is 5 with a remainder of 425.
The next digit of our result is 5. 
Result so far: 89460.25
Subtract 4395 from 4820 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 11:
879 goes into 4250 4 times with a remainder of 734.
Put 4 as the next digit of the answer. 
Result so far: 89460.254
Deduct 3516 from 4250 and we're left with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

On to step 12:
879 can be fit into 7340 8 times, resulting in a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 89460.2548
Subtract 7032 from 7340 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 13:
879 goes into 3080 3 times with a remainder of 443.
Use 3 as the next digit of our solution. 
Result so far: 89460.25483
Subtract 2637 from 3080 to get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 14:
879 can be fit into 4430 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 89460.254835
If we take 4395 away from 4430, we end up 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.

Moving on to step 15:
879 can be fit into 350 0 times, resulting in a remainder of 350.
The next digit of our result is 0. 
Result so far: 89460.254835
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.

Going ahead to step 16:
If we divide 3500 by 879, we get 3 and a remainder of 863.
Put 3 as the next digit of the answer. 
Result so far: 89460.25483503
Subtract 2637 from 3500 to get 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

The final result is 89460.25483503 with a remainder of 8.63e-07.
