We look at the division of 86990180 by 915 
We're looking to find how many times 915 goes into 86990180.

Let's proceed to step 1:
If we divide 8 by 915, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 915

On to step 2:
The number 915 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 915

On to step 3:
869 divided by 915 is 0 with a remainder of 869.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 869 and we're left with 869.
Bring next digit (9) of the dividend behind the 869 and repeat the process: 8699 / 915

Going ahead to step 4:
If we divide 8699 by 915, we get 9 and a remainder of 464.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 8235 from 8699 leaves us with 464.
Append the next digit (0) from the dividend to 464 and continue with: 4640 / 915

Moving on to step 5:
When dividing 4640 by 915, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 95.0
If we take 4575 away from 4640, we end up with 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 915

Going ahead to step 6:
915 goes into 651 0 times with a remainder of 651.
Record the quotient 0 as the next digit in the result. 
Result so far: 950.0
If we take 0 away from 651, we end up with 651.
Bring next digit (8) of the dividend behind the 651 and repeat the process: 6518 / 915

Going ahead to step 7:
915 goes into 6518 7 times with a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 9507.0
Subtracting 6405 from 6518 leaves us with 113.
Take the next digit (0) from the dividend and append it to 113, then repeat: 1130 / 915

On to step 8:
915 goes into 1130 1 times with a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 95071.0
If we subtract 915 from 1130, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 9:
915 goes into 2150 2 times with a remainder of 320.
The next digit of our result is 2. 
Result so far: 95071.2
Subtract 1830 from 2150 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 10:
If we divide 3200 by 915, we get 3 and a remainder of 455.
The next digit of our result is 3. 
Result so far: 95071.23
If we subtract 2745 from 3200, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Advancing to step 11:
915 can be fit into 4550 4 times, resulting in a remainder of 890.
Use 4 as the next digit of our solution. 
Result so far: 95071.234
Subtracting 3660 from 4550 leaves us with 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Step 12:
The number 915 fits into 8900 9 times, leaving a remainder of 665.
The number 9 becomes the next digit in our result. 
Result so far: 95071.2349
If we subtract 8235 from 8900, we get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Let's proceed to step 13:
915 goes into 6650 7 times with a remainder of 245.
Put 7 as the next digit of the answer. 
Result so far: 95071.23497
Subtracting 6405 from 6650 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 14:
915 goes into 2450 2 times with a remainder of 620.
Use 2 as the next digit of our solution. 
Result so far: 95071.234972
The remainder is 620 after subtracting 1830 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 15:
915 goes into 6200 6 times with a remainder of 710.
Record the quotient 6 as the next digit in the result. 
Result so far: 95071.2349726
The remainder is 710 after subtracting 5490 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 16:
If we divide 7100 by 915, we get 7 and a remainder of 695.
The next digit of our result is 7. 
Result so far: 95071.23497267
Subtract 6405 from 7100 to get 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

After the division, we end up with 95071.23497267 and a remainder of 6.95e-07.
