Let's divide 69971199 by 870
Our goal is to divide 69971199 by 870.

Step 1:
870 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 870

Let's proceed to step 2:
870 goes into 69 0 times with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 870

Let's proceed to step 3:
870 can be fit into 699 0 times, resulting in a remainder of 699.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 699 leaves us with 699.
Append the next digit (7) from the dividend to 699 and continue with: 6997 / 870

On to step 4:
870 goes into 6997 8 times with a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6960 from 6997 to get 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 870

Moving on to step 5:
870 goes into 371 0 times with a remainder of 371.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtract 0 from 371 to get 371.
Append the next digit (1) from the dividend to 371 and continue with: 3711 / 870

Going ahead to step 6:
If we divide 3711 by 870, we get 4 and a remainder of 231.
The next digit of our result is 4. 
Result so far: 804.0
If we take 3480 away from 3711, we end up with 231.
Bring next digit (9) of the dividend behind the 231 and repeat the process: 2319 / 870

Moving on to step 7:
2319 divided by 870 is 2 with a remainder of 579.
Put 2 as the next digit of the answer. 
Result so far: 8042.0
The remainder is 579 after subtracting 1740 from 2319.
Append the next digit (9) from the dividend to 579 and continue with: 5799 / 870

Going ahead to step 8:
If we divide 5799 by 870, we get 6 and a remainder of 579.
The next digit of our result is 6. 
Result so far: 80426.0
If we take 5220 away from 5799, we end up with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Moving on to step 9:
870 goes into 5790 6 times with a remainder of 570.
The number 6 becomes the next digit in our result. 
Result so far: 80426.6
Deduct 5220 from 5790 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 10:
870 can be fit into 5700 6 times, resulting in a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 80426.66
Deduct 5220 from 5700 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Our division results in 80426.66 with a remaining 0.48.
