We're dividing 86237019 by 899 
We want to figure out the number of times 86237019 can be divided by 899.

On to step 1:
899 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
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 899

Step 2:
The number 899 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 899

Advancing to step 3:
If we divide 862 by 899, we get 0 and a remainder of 862.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 862 leaves us with 862.
Append the next digit (3) from the dividend to 862 and continue with: 8623 / 899

On to step 4:
If we divide 8623 by 899, we get 9 and a remainder of 532.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 532 after subtracting 8091 from 8623.
Grab the next digit (7) from the dividend, add it to 532, then carry on: 5327 / 899

Step 5:
899 can be fit into 5327 5 times, resulting in a remainder of 832.
The next digit of our result is 5. 
Result so far: 95.0
Deduct 4495 from 5327 and we're left with 832.
Fetch the next digit (0) from the dividend, attach it to 832 and continue: 8320 / 899

On to step 6:
When dividing 8320 by 899, we get 9 with a remainder of 229.
Write down 9 as next digit of the result. 
Result so far: 959.0
Subtracting 8091 from 8320 leaves us with 229.
Bring next digit (1) of the dividend behind the 229 and repeat the process: 2291 / 899

On to step 7:
If we divide 2291 by 899, we get 2 and a remainder of 493.
Put 2 as the next digit of the answer. 
Result so far: 9592.0
Subtracting 1798 from 2291 leaves us with 493.
Include the next digit (9) from the dividend after 493, then repeat: 4939 / 899

On to step 8:
If we divide 4939 by 899, we get 5 and a remainder of 444.
Record the quotient 5 as the next digit in the result. 
Result so far: 95925.0
The remainder is 444 after subtracting 4495 from 4939.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 9:
899 goes into 4440 4 times with a remainder of 844.
Put 4 as the next digit of the answer. 
Result so far: 95925.4
Subtract 3596 from 4440 to get 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

On to step 10:
When dividing 8440 by 899, we get 9 with a remainder of 349.
Record the quotient 9 as the next digit in the result. 
Result so far: 95925.49
If we take 8091 away from 8440, we end up with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 11:
The number 899 fits into 3490 3 times, leaving a remainder of 793.
Put 3 as the next digit of the answer. 
Result so far: 95925.493
Deduct 2697 from 3490 and we're left with 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Step 12:
When dividing 7930 by 899, we get 8 with a remainder of 738.
The next digit of our result is 8. 
Result so far: 95925.4938
Subtracting 7192 from 7930 leaves us with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Going ahead to step 13:
7380 divided by 899 is 8 with a remainder of 188.
Record the quotient 8 as the next digit in the result. 
Result so far: 95925.49388
If we take 7192 away from 7380, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Our division results in 95925.49388 with a remaining 0.000188.
