We look at the division of 81352124 by 412 
We want to divide 81352124 by 412.

Advancing to step 1:
412 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 412

Let's proceed to step 2:
If we divide 81 by 412, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 412

Step 3:
412 can be fit into 813 1 times, resulting in a remainder of 401.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 412 from 813, we get 401.
Take the next digit (5) from the dividend and append it to 401, then repeat: 4015 / 412

Moving on to step 4:
If we divide 4015 by 412, we get 9 and a remainder of 307.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 307 after subtracting 3708 from 4015.
Append the next digit (2) from the dividend to 307 and continue with: 3072 / 412

On to step 5:
The number 412 fits into 3072 7 times, leaving a remainder of 188.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Deduct 2884 from 3072 and we're left with 188.
Fetch the next digit (1) from the dividend, attach it to 188 and continue: 1881 / 412

Advancing to step 6:
When dividing 1881 by 412, we get 4 with a remainder of 233.
Record the quotient 4 as the next digit in the result. 
Result so far: 1974.0
Subtract 1648 from 1881 to get 233.
Append the next digit (2) from the dividend to 233 and continue with: 2332 / 412

Step 7:
412 can be fit into 2332 5 times, resulting in a remainder of 272.
Use 5 as the next digit of our solution. 
Result so far: 19745.0
Deduct 2060 from 2332 and we're left with 272.
Take the next digit (4) from the dividend and append it to 272, then repeat: 2724 / 412

Let's proceed to step 8:
412 can be fit into 2724 6 times, resulting in a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 197456.0
If we take 2472 away from 2724, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 9:
When dividing 2520 by 412, we get 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 197456.6
The remainder is 48 after subtracting 2472 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
If we divide 480 by 412, we get 1 and a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 197456.61
Subtracting 412 from 480 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
412 can be fit into 680 1 times, resulting in a remainder of 268.
Put 1 as the next digit of the answer. 
Result so far: 197456.611
If we take 412 away from 680, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Our division results in 197456.611 with a remaining 0.0268.
