Let's divide 87249099 by 879
We want to divide 87249099 by 879.

Moving on to step 1:
879 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 879

Moving on to step 2:
879 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Append the next digit (2) from the dividend to 87 and continue with: 872 / 879

On to step 3:
The number 879 fits into 872 0 times, leaving a remainder of 872.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 872 and we're left with 872.
Append the next digit (4) from the dividend to 872 and continue with: 8724 / 879

Let's proceed to step 4:
8724 divided by 879 is 9 with a remainder of 813.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 7911 from 8724 to get 813.
Bring next digit (9) of the dividend behind the 813 and repeat the process: 8139 / 879

On to step 5:
The number 879 fits into 8139 9 times, leaving a remainder of 228.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we take 7911 away from 8139, we end up with 228.
Include the next digit (0) from the dividend after 228, then repeat: 2280 / 879

Advancing to step 6:
If we divide 2280 by 879, we get 2 and a remainder of 522.
Put 2 as the next digit of the answer. 
Result so far: 992.0
Deduct 1758 from 2280 and we're left with 522.
Take the next digit (9) from the dividend and append it to 522, then repeat: 5229 / 879

Moving on to step 7:
If we divide 5229 by 879, we get 5 and a remainder of 834.
Use 5 as the next digit of our solution. 
Result so far: 9925.0
Subtract 4395 from 5229 to get 834.
Take the next digit (9) from the dividend and append it to 834, then repeat: 8349 / 879

Going ahead to step 8:
879 can be fit into 8349 9 times, resulting in a remainder of 438.
Put 9 as the next digit of the answer. 
Result so far: 99259.0
If we take 7911 away from 8349, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 9:
When dividing 4380 by 879, we get 4 with a remainder of 864.
Write down 4 as next digit of the result. 
Result so far: 99259.4
If we take 3516 away from 4380, we end up with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Let's proceed to step 10:
8640 divided by 879 is 9 with a remainder of 729.
Record the quotient 9 as the next digit in the result. 
Result so far: 99259.49
If we subtract 7911 from 8640, we get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Let's proceed to step 11:
879 goes into 7290 8 times with a remainder of 258.
Record the quotient 8 as the next digit in the result. 
Result so far: 99259.498
If we take 7032 away from 7290, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 12:
The number 879 fits into 2580 2 times, leaving a remainder of 822.
The next digit of our result is 2. 
Result so far: 99259.4982
If we take 1758 away from 2580, we end up with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Going ahead to step 13:
When dividing 8220 by 879, we get 9 with a remainder of 309.
Put 9 as the next digit of the answer. 
Result so far: 99259.49829
If we subtract 7911 from 8220, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 14:
879 can be fit into 3090 3 times, resulting in a remainder of 453.
The number 3 becomes the next digit in our result. 
Result so far: 99259.498293
If we take 2637 away from 3090, we end up with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Step 15:
If we divide 4530 by 879, we get 5 and a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 99259.4982935
Deduct 4395 from 4530 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 16:
1350 divided by 879 is 1 with a remainder of 471.
Write down 1 as next digit of the result. 
Result so far: 99259.49829351
Subtract 879 from 1350 to get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

In conclusion, the division gives 99259.49829351 with a balance of 4.71e-07.
