We divide 88515140 by 870
We want to divide 88515140 by 870.

Let's proceed to step 1:
If we divide 8 by 870, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 870

Let's proceed to step 2:
When dividing 88 by 870, we get 0 with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Append the next digit (5) from the dividend to 88 and continue with: 885 / 870

Going ahead to step 3:
870 goes into 885 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 870 from 885 and we're left with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 870

Advancing to step 4:
The number 870 fits into 151 0 times, leaving a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 151, we end up with 151.
Take the next digit (5) from the dividend and append it to 151, then repeat: 1515 / 870

Going ahead to step 5:
870 can be fit into 1515 1 times, resulting in a remainder of 645.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtracting 870 from 1515 leaves us with 645.
Bring next digit (1) of the dividend behind the 645 and repeat the process: 6451 / 870

Step 6:
When dividing 6451 by 870, we get 7 with a remainder of 361.
The next digit of our result is 7. 
Result so far: 1017.0
Subtract 6090 from 6451 to get 361.
Append the next digit (4) from the dividend to 361 and continue with: 3614 / 870

Let's proceed to step 7:
If we divide 3614 by 870, we get 4 and a remainder of 134.
Use 4 as the next digit of our solution. 
Result so far: 10174.0
The remainder is 134 after subtracting 3480 from 3614.
Include the next digit (0) from the dividend after 134, then repeat: 1340 / 870

Advancing to step 8:
The number 870 fits into 1340 1 times, leaving a remainder of 470.
Write down 1 as next digit of the result. 
Result so far: 101741.0
Subtract 870 from 1340 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 9:
870 goes into 4700 5 times with a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 101741.5
If we take 4350 away from 4700, we end up 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.

Step 10:
The number 870 fits into 3500 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 101741.54
If we take 3480 away from 3500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
When dividing 200 by 870, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 101741.54
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
If we divide 2000 by 870, we get 2 and a remainder of 260.
Put 2 as the next digit of the answer. 
Result so far: 101741.5402
Deduct 1740 from 2000 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 13:
The number 870 fits into 2600 2 times, leaving a remainder of 860.
Write down 2 as next digit of the result. 
Result so far: 101741.54022
If we subtract 1740 from 2600, we get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

The final result is 101741.54022 with a remainder of 0.00086.
