We look at the division of 81265447 by 663 
We want to divide 81265447 by 663.

Step 1:
8 divided by 663 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 663

Moving on to step 2:
If we divide 81 by 663, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 663

Moving on to step 3:
663 goes into 812 1 times with a remainder of 149.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 663 from 812, we get 149.
Fetch the next digit (6) from the dividend, attach it to 149 and continue: 1496 / 663

Moving on to step 4:
663 goes into 1496 2 times with a remainder of 170.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1326 from 1496 to get 170.
Append the next digit (5) from the dividend to 170 and continue with: 1705 / 663

Advancing to step 5:
663 goes into 1705 2 times with a remainder of 379.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtract 1326 from 1705 to get 379.
Include the next digit (4) from the dividend after 379, then repeat: 3794 / 663

Advancing to step 6:
663 goes into 3794 5 times with a remainder of 479.
The next digit of our result is 5. 
Result so far: 1225.0
If we subtract 3315 from 3794, we get 479.
Include the next digit (4) from the dividend after 479, then repeat: 4794 / 663

Step 7:
If we divide 4794 by 663, we get 7 and a remainder of 153.
Write down 7 as next digit of the result. 
Result so far: 12257.0
Subtracting 4641 from 4794 leaves us with 153.
Take the next digit (7) from the dividend and append it to 153, then repeat: 1537 / 663

Let's proceed to step 8:
663 can be fit into 1537 2 times, resulting in a remainder of 211.
Record the quotient 2 as the next digit in the result. 
Result so far: 122572.0
Subtract 1326 from 1537 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 9:
The number 663 fits into 2110 3 times, leaving a remainder of 121.
Write down 3 as next digit of the result. 
Result so far: 122572.3
If we subtract 1989 from 2110, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 10:
1210 divided by 663 is 1 with a remainder of 547.
The number 1 becomes the next digit in our result. 
Result so far: 122572.31
If we subtract 663 from 1210, we get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Advancing to step 11:
663 can be fit into 5470 8 times, resulting in a remainder of 166.
Write down 8 as next digit of the result. 
Result so far: 122572.318
Subtracting 5304 from 5470 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 12:
If we divide 1660 by 663, we get 2 and a remainder of 334.
The number 2 becomes the next digit in our result. 
Result so far: 122572.3182
Subtracting 1326 from 1660 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 13:
663 can be fit into 3340 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 122572.31825
The remainder is 25 after subtracting 3315 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
If we divide 250 by 663, we get 0 and a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 122572.31825
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 15:
If we divide 2500 by 663, we get 3 and a remainder of 511.
The number 3 becomes the next digit in our result. 
Result so far: 122572.3182503
The remainder is 511 after subtracting 1989 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Let's proceed to step 16:
The number 663 fits into 5110 7 times, leaving a remainder of 469.
The next digit of our result is 7. 
Result so far: 122572.31825037
Subtract 4641 from 5110 to get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

After the division, we end up with 122572.31825037 and a remainder of 4.69e-07.
