We're dividing 81112988 by 904 
We want to divide 81112988 by 904.

Step 1:
When dividing 8 by 904, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 904

Going ahead to step 2:
904 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 904

Advancing to step 3:
811 divided by 904 is 0 with a remainder of 811.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 811, we end up with 811.
Grab the next digit (1) from the dividend, add it to 811, then carry on: 8111 / 904

Advancing to step 4:
904 can be fit into 8111 8 times, resulting in a remainder of 879.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 7232 from 8111 leaves us with 879.
Grab the next digit (2) from the dividend, add it to 879, then carry on: 8792 / 904

Advancing to step 5:
When dividing 8792 by 904, we get 9 with a remainder of 656.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we take 8136 away from 8792, we end up with 656.
Grab the next digit (9) from the dividend, add it to 656, then carry on: 6569 / 904

Step 6:
6569 divided by 904 is 7 with a remainder of 241.
Write down 7 as next digit of the result. 
Result so far: 897.0
The remainder is 241 after subtracting 6328 from 6569.
Fetch the next digit (8) from the dividend, attach it to 241 and continue: 2418 / 904

Let's proceed to step 7:
The number 904 fits into 2418 2 times, leaving a remainder of 610.
Use 2 as the next digit of our solution. 
Result so far: 8972.0
If we take 1808 away from 2418, we end up with 610.
Fetch the next digit (8) from the dividend, attach it to 610 and continue: 6108 / 904

Step 8:
When dividing 6108 by 904, we get 6 with a remainder of 684.
The next digit of our result is 6. 
Result so far: 89726.0
The remainder is 684 after subtracting 5424 from 6108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 9:
The number 904 fits into 6840 7 times, leaving a remainder of 512.
The next digit of our result is 7. 
Result so far: 89726.7
Subtract 6328 from 6840 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 10:
The number 904 fits into 5120 5 times, leaving a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 89726.75
Subtract 4520 from 5120 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
904 can be fit into 6000 6 times, resulting in a remainder of 576.
The number 6 becomes the next digit in our result. 
Result so far: 89726.756
Subtracting 5424 from 6000 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 12:
When dividing 5760 by 904, we get 6 with a remainder of 336.
The number 6 becomes the next digit in our result. 
Result so far: 89726.7566
If we subtract 5424 from 5760, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final result is 89726.7566 with a remainder of 0.00336.
