We're dividing 81120065 by 23 
Let's see how many times 23 fits into 81120065.

Step 1:
8 divided by 23 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 23

Advancing to step 2:
The number 23 fits into 81 3 times, leaving a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 12 after subtracting 69 from 81.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 23

Advancing to step 3:
23 can be fit into 121 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 115 from 121 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 23

Let's proceed to step 4:
If we divide 62 by 23, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 352.0
Subtract 46 from 62 to get 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 23

Going ahead to step 5:
160 divided by 23 is 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 3526.0
If we subtract 138 from 160, we get 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 23

On to step 6:
220 divided by 23 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 35269.0
Subtract 207 from 220 to get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 23

Step 7:
23 goes into 136 5 times with a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 352695.0
Subtracting 115 from 136 leaves us with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 23

Step 8:
215 divided by 23 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 3526959.0
Subtract 207 from 215 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 23 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3526959.3
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
23 goes into 110 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 3526959.34
Subtracting 92 from 110 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
If we divide 180 by 23, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 3526959.347
Subtract 161 from 180 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
23 goes into 190 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 3526959.3478
If we take 184 away from 190, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
The number 23 fits into 60 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 3526959.34782
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
When dividing 140 by 23, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 3526959.347826
Deduct 138 from 140 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 15:
23 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3526959.347826
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 16:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3526959.34782608
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 3526959.34782608, and the remainder is 1.6e-08.
