86398037 divided by 215 
We want to figure out the number of times 86398037 can be divided by 215.

Let's proceed to step 1:
8 divided by 215 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 215

Advancing to step 2:
If we divide 86 by 215, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (3) from the dividend after 86, then repeat: 863 / 215

Advancing to step 3:
If we divide 863 by 215, we get 4 and a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 860 from 863, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 215

Step 4:
If we divide 39 by 215, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 215

On to step 5:
When dividing 398 by 215, we get 1 with a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 401.0
If we subtract 215 from 398, we get 183.
Include the next digit (0) from the dividend after 183, then repeat: 1830 / 215

Step 6:
The number 215 fits into 1830 8 times, leaving a remainder of 110.
The next digit of our result is 8. 
Result so far: 4018.0
If we subtract 1720 from 1830, we get 110.
Bring next digit (3) of the dividend behind the 110 and repeat the process: 1103 / 215

Moving on to step 7:
215 can be fit into 1103 5 times, resulting in a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 40185.0
Deduct 1075 from 1103 and we're left with 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 215

Going ahead to step 8:
When dividing 287 by 215, we get 1 with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 401851.0
Deduct 215 from 287 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
720 divided by 215 is 3 with a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 401851.3
The remainder is 75 after subtracting 645 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
750 divided by 215 is 3 with a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 401851.33
If we subtract 645 from 750, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 401851.33, and the remainder is 0.105.
