We look at the division of 12093811 by 810 
We want to divide 12093811 by 810.

Going ahead to step 1:
1 divided by 810 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 810

Step 2:
When dividing 12 by 810, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 810

Moving on to step 3:
810 goes into 120 0 times with a remainder of 120.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 120, we end up with 120.
Take the next digit (9) from the dividend and append it to 120, then repeat: 1209 / 810

Moving on to step 4:
If we divide 1209 by 810, we get 1 and a remainder of 399.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 810 away from 1209, we end up with 399.
Bring next digit (3) of the dividend behind the 399 and repeat the process: 3993 / 810

Advancing to step 5:
810 goes into 3993 4 times with a remainder of 753.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 3240 from 3993, we get 753.
Take the next digit (8) from the dividend and append it to 753, then repeat: 7538 / 810

Going ahead to step 6:
If we divide 7538 by 810, we get 9 and a remainder of 248.
The next digit of our result is 9. 
Result so far: 149.0
Deduct 7290 from 7538 and we're left with 248.
Append the next digit (1) from the dividend to 248 and continue with: 2481 / 810

Step 7:
The number 810 fits into 2481 3 times, leaving a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 1493.0
Subtract 2430 from 2481 to get 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 810

Going ahead to step 8:
810 goes into 511 0 times with a remainder of 511.
Use 0 as the next digit of our solution. 
Result so far: 14930.0
Subtracting 0 from 511 leaves us with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Going ahead to step 9:
5110 divided by 810 is 6 with a remainder of 250.
The number 6 becomes the next digit in our result. 
Result so far: 14930.6
Subtracting 4860 from 5110 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.

Moving on to step 10:
The number 810 fits into 2500 3 times, leaving a remainder of 70.
The next digit of our result is 3. 
Result so far: 14930.63
Deduct 2430 from 2500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
When dividing 700 by 810, we get 0 with a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 14930.63
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 12:
810 goes into 7000 8 times with a remainder of 520.
The next digit of our result is 8. 
Result so far: 14930.6308
Subtract 6480 from 7000 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 13:
The number 810 fits into 5200 6 times, leaving a remainder of 340.
The next digit of our result is 6. 
Result so far: 14930.63086
Subtract 4860 from 5200 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 14:
3400 divided by 810 is 4 with a remainder of 160.
Write down 4 as next digit of the result. 
Result so far: 14930.630864
Subtract 3240 from 3400 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
If we divide 1600 by 810, we get 1 and a remainder of 790.
The number 1 becomes the next digit in our result. 
Result so far: 14930.6308641
Subtract 810 from 1600 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 16:
When dividing 7900 by 810, we get 9 with a remainder of 610.
Use 9 as the next digit of our solution. 
Result so far: 14930.63086419
If we subtract 7290 from 7900, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

The quotient of the division is 14930.63086419, and the remainder is 6.1e-07.
