We look at the division of 81209471 by 403 
We want to figure out the number of times 81209471 can be divided by 403.

Moving on to step 1:
403 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 403

Going ahead to step 2:
When dividing 81 by 403, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 403

Step 3:
403 can be fit into 812 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 806 from 812, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 403

Step 4:
60 divided by 403 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 60, we end up with 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 403

Moving on to step 5:
If we divide 609 by 403, we get 1 and a remainder of 206.
Use 1 as the next digit of our solution. 
Result so far: 201.0
If we take 403 away from 609, we end up with 206.
Take the next digit (4) from the dividend and append it to 206, then repeat: 2064 / 403

Advancing to step 6:
When dividing 2064 by 403, we get 5 with a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 2015.0
Deduct 2015 from 2064 and we're left with 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 403

Let's proceed to step 7:
If we divide 497 by 403, we get 1 and a remainder of 94.
The next digit of our result is 1. 
Result so far: 20151.0
Subtracting 403 from 497 leaves us with 94.
Grab the next digit (1) from the dividend, add it to 94, then carry on: 941 / 403

On to step 8:
If we divide 941 by 403, we get 2 and a remainder of 135.
Put 2 as the next digit of the answer. 
Result so far: 201512.0
If we take 806 away from 941, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 9:
The number 403 fits into 1350 3 times, leaving a remainder of 141.
The number 3 becomes the next digit in our result. 
Result so far: 201512.3
Deduct 1209 from 1350 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 10:
403 goes into 1410 3 times with a remainder of 201.
Record the quotient 3 as the next digit in the result. 
Result so far: 201512.33
Subtracting 1209 from 1410 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

The final outcome is 201512.33, with a leftover of 0.201.
