We divide 86816137 by 815
We want to figure out the number of times 86816137 can be divided by 815.

Let's proceed to step 1:
815 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 815

Advancing to step 2:
815 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 815

Step 3:
When dividing 868 by 815, we get 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 53 after subtracting 815 from 868.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 815

On to step 4:
When dividing 531 by 815, we get 0 with a remainder of 531.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 531 to get 531.
Take the next digit (6) from the dividend and append it to 531, then repeat: 5316 / 815

Let's proceed to step 5:
815 goes into 5316 6 times with a remainder of 426.
Write down 6 as next digit of the result. 
Result so far: 106.0
The remainder is 426 after subtracting 4890 from 5316.
Take the next digit (1) from the dividend and append it to 426, then repeat: 4261 / 815

On to step 6:
815 goes into 4261 5 times with a remainder of 186.
The next digit of our result is 5. 
Result so far: 1065.0
If we take 4075 away from 4261, we end up with 186.
Include the next digit (3) from the dividend after 186, then repeat: 1863 / 815

On to step 7:
815 goes into 1863 2 times with a remainder of 233.
The number 2 becomes the next digit in our result. 
Result so far: 10652.0
If we take 1630 away from 1863, we end up with 233.
Take the next digit (7) from the dividend and append it to 233, then repeat: 2337 / 815

Let's proceed to step 8:
815 goes into 2337 2 times with a remainder of 707.
The number 2 becomes the next digit in our result. 
Result so far: 106522.0
Subtract 1630 from 2337 to get 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

Step 9:
If we divide 7070 by 815, we get 8 and a remainder of 550.
Record the quotient 8 as the next digit in the result. 
Result so far: 106522.8
Deduct 6520 from 7070 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 10:
When dividing 5500 by 815, we get 6 with a remainder of 610.
The next digit of our result is 6. 
Result so far: 106522.86
Subtract 4890 from 5500 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 11:
When dividing 6100 by 815, we get 7 with a remainder of 395.
The number 7 becomes the next digit in our result. 
Result so far: 106522.867
If we take 5705 away from 6100, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Let's proceed to step 12:
The number 815 fits into 3950 4 times, leaving a remainder of 690.
The number 4 becomes the next digit in our result. 
Result so far: 106522.8674
Subtract 3260 from 3950 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 13:
If we divide 6900 by 815, we get 8 and a remainder of 380.
Use 8 as the next digit of our solution. 
Result so far: 106522.86748
The remainder is 380 after subtracting 6520 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 14:
The number 815 fits into 3800 4 times, leaving a remainder of 540.
Put 4 as the next digit of the answer. 
Result so far: 106522.867484
If we take 3260 away from 3800, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 15:
815 can be fit into 5400 6 times, resulting in a remainder of 510.
Write down 6 as next digit of the result. 
Result so far: 106522.8674846
The remainder is 510 after subtracting 4890 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 16:
815 can be fit into 5100 6 times, resulting in a remainder of 210.
Use 6 as the next digit of our solution. 
Result so far: 106522.86748466
Subtract 4890 from 5100 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Our division results in 106522.86748466 with a remaining 2.1e-07.
