We look at the division of 71190386 by 900 
Our goal is to divide 71190386 by 900.

On to step 1:
When dividing 7 by 900, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 900

Advancing to step 2:
The number 900 fits into 71 0 times, leaving a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Append the next digit (1) from the dividend to 71 and continue with: 711 / 900

Advancing to step 3:
900 can be fit into 711 0 times, resulting in a remainder of 711.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 711, we get 711.
Grab the next digit (9) from the dividend, add it to 711, then carry on: 7119 / 900

Step 4:
900 can be fit into 7119 7 times, resulting in a remainder of 819.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 6300 away from 7119, we end up with 819.
Fetch the next digit (0) from the dividend, attach it to 819 and continue: 8190 / 900

Moving on to step 5:
The number 900 fits into 8190 9 times, leaving a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 90 after subtracting 8100 from 8190.
Include the next digit (3) from the dividend after 90, then repeat: 903 / 900

Going ahead to step 6:
When dividing 903 by 900, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 791.0
Deduct 900 from 903 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 900

Step 7:
38 divided by 900 is 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 7910.0
If we subtract 0 from 38, we get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 900

Let's proceed to step 8:
When dividing 386 by 900, we get 0 with a remainder of 386.
Record the quotient 0 as the next digit in the result. 
Result so far: 79100.0
The remainder is 386 after subtracting 0 from 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 9:
900 can be fit into 3860 4 times, resulting in a remainder of 260.
Use 4 as the next digit of our solution. 
Result so far: 79100.4
If we take 3600 away from 3860, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
When dividing 2600 by 900, we get 2 with a remainder of 800.
Write down 2 as next digit of the result. 
Result so far: 79100.42
If we take 1800 away from 2600, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 11:
8000 divided by 900 is 8 with a remainder of 800.
Record the quotient 8 as the next digit in the result. 
Result so far: 79100.428
If we subtract 7200 from 8000, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 12:
When dividing 8000 by 900, we get 8 with a remainder of 800.
The next digit of our result is 8. 
Result so far: 79100.4288
If we subtract 7200 from 8000, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The quotient of the division is 79100.4288, and the remainder is 0.008.
