Let's divide 99812702 by 409
Our goal is to divide 99812702 by 409.

Let's proceed to step 1:
409 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 409

Going ahead to step 2:
409 can be fit into 99 0 times, resulting in a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Bring next digit (8) of the dividend behind the 99 and repeat the process: 998 / 409

Advancing to step 3:
998 divided by 409 is 2 with a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 818 from 998 to get 180.
Grab the next digit (1) from the dividend, add it to 180, then carry on: 1801 / 409

Moving on to step 4:
409 can be fit into 1801 4 times, resulting in a remainder of 165.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 1636 from 1801 to get 165.
Include the next digit (2) from the dividend after 165, then repeat: 1652 / 409

Let's proceed to step 5:
1652 divided by 409 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 244.0
Subtract 1636 from 1652 to get 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 409

Going ahead to step 6:
If we divide 167 by 409, we get 0 and a remainder of 167.
Write down 0 as next digit of the result. 
Result so far: 2440.0
If we take 0 away from 167, we end up with 167.
Append the next digit (0) from the dividend to 167 and continue with: 1670 / 409

Advancing to step 7:
When dividing 1670 by 409, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 24404.0
Subtract 1636 from 1670 to get 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 409

Advancing to step 8:
The number 409 fits into 342 0 times, leaving a remainder of 342.
Record the quotient 0 as the next digit in the result. 
Result so far: 244040.0
If we subtract 0 from 342, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 9:
3420 divided by 409 is 8 with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 244040.8
Subtract 3272 from 3420 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 10:
1480 divided by 409 is 3 with a remainder of 253.
Write down 3 as next digit of the result. 
Result so far: 244040.83
Subtract 1227 from 1480 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Going ahead to step 11:
When dividing 2530 by 409, we get 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 244040.836
If we take 2454 away from 2530, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
760 divided by 409 is 1 with a remainder of 351.
The number 1 becomes the next digit in our result. 
Result so far: 244040.8361
The remainder is 351 after subtracting 409 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 13:
When dividing 3510 by 409, we get 8 with a remainder of 238.
Record the quotient 8 as the next digit in the result. 
Result so far: 244040.83618
Deduct 3272 from 3510 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 14:
When dividing 2380 by 409, we get 5 with a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 244040.836185
The remainder is 335 after subtracting 2045 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 15:
3350 divided by 409 is 8 with a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 244040.8361858
Subtract 3272 from 3350 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 16:
780 divided by 409 is 1 with a remainder of 371.
Write down 1 as next digit of the result. 
Result so far: 244040.83618581
Deduct 409 from 780 and we're left with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

The final outcome is 244040.83618581, with a leftover of 3.71e-07.
