We look at the division of 86219769 by 900 
Let's see how many times 900 fits into 86219769.

Advancing to step 1:
900 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 900

Going ahead to step 2:
When dividing 86 by 900, we get 0 with 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.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 900

On to step 3:
900 can be fit into 862 0 times, resulting in a remainder of 862.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 862 and we're left with 862.
Grab the next digit (1) from the dividend, add it to 862, then carry on: 8621 / 900

Advancing to step 4:
The number 900 fits into 8621 9 times, leaving a remainder of 521.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 8100 from 8621, we get 521.
Include the next digit (9) from the dividend after 521, then repeat: 5219 / 900

Moving on to step 5:
5219 divided by 900 is 5 with a remainder of 719.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Deduct 4500 from 5219 and we're left with 719.
Append the next digit (7) from the dividend to 719 and continue with: 7197 / 900

Let's proceed to step 6:
900 goes into 7197 7 times with a remainder of 897.
Use 7 as the next digit of our solution. 
Result so far: 957.0
Deduct 6300 from 7197 and we're left with 897.
Grab the next digit (6) from the dividend, add it to 897, then carry on: 8976 / 900

Going ahead to step 7:
900 goes into 8976 9 times with a remainder of 876.
Use 9 as the next digit of our solution. 
Result so far: 9579.0
Subtracting 8100 from 8976 leaves us with 876.
Bring next digit (9) of the dividend behind the 876 and repeat the process: 8769 / 900

Advancing to step 8:
If we divide 8769 by 900, we get 9 and a remainder of 669.
The next digit of our result is 9. 
Result so far: 95799.0
Subtract 8100 from 8769 to get 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Going ahead to step 9:
If we divide 6690 by 900, we get 7 and a remainder of 390.
The next digit of our result is 7. 
Result so far: 95799.7
If we subtract 6300 from 6690, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
When dividing 3900 by 900, we get 4 with a remainder of 300.
Record the quotient 4 as the next digit in the result. 
Result so far: 95799.74
Deduct 3600 from 3900 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
900 can be fit into 3000 3 times, resulting in a remainder of 300.
Write down 3 as next digit of the result. 
Result so far: 95799.743
The remainder is 300 after subtracting 2700 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 12:
If we divide 3000 by 900, we get 3 and a remainder of 300.
Use 3 as the next digit of our solution. 
Result so far: 95799.7433
Subtracting 2700 from 3000 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 95799.7433 and a remainder of 0.003.
