We look at the division of 81353809 by 679 
Let's see how many times 679 fits into 81353809.

On to step 1:
When dividing 8 by 679, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 679

Advancing to step 2:
679 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 679

Advancing to step 3:
679 goes into 813 1 times with a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 679 away from 813, we end up with 134.
Bring next digit (5) of the dividend behind the 134 and repeat the process: 1345 / 679

Advancing to step 4:
The number 679 fits into 1345 1 times, leaving a remainder of 666.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 679 from 1345 leaves us with 666.
Include the next digit (3) from the dividend after 666, then repeat: 6663 / 679

Step 5:
The number 679 fits into 6663 9 times, leaving a remainder of 552.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
If we take 6111 away from 6663, we end up with 552.
Bring next digit (8) of the dividend behind the 552 and repeat the process: 5528 / 679

Moving on to step 6:
5528 divided by 679 is 8 with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 1198.0
Deduct 5432 from 5528 and we're left with 96.
Grab the next digit (0) from the dividend, add it to 96, then carry on: 960 / 679

On to step 7:
When dividing 960 by 679, we get 1 with a remainder of 281.
Put 1 as the next digit of the answer. 
Result so far: 11981.0
If we take 679 away from 960, we end up with 281.
Take the next digit (9) from the dividend and append it to 281, then repeat: 2819 / 679

Moving on to step 8:
679 can be fit into 2819 4 times, resulting in a remainder of 103.
Record the quotient 4 as the next digit in the result. 
Result so far: 119814.0
Subtract 2716 from 2819 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 9:
679 goes into 1030 1 times with a remainder of 351.
Write down 1 as next digit of the result. 
Result so far: 119814.1
The remainder is 351 after subtracting 679 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 10:
679 goes into 3510 5 times with a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 119814.15
Subtract 3395 from 3510 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 11:
The number 679 fits into 1150 1 times, leaving a remainder of 471.
Write down 1 as next digit of the result. 
Result so far: 119814.151
Deduct 679 from 1150 and we're left with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Going ahead to step 12:
679 can be fit into 4710 6 times, resulting in a remainder of 636.
Write down 6 as next digit of the result. 
Result so far: 119814.1516
If we take 4074 away from 4710, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 13:
The number 679 fits into 6360 9 times, leaving a remainder of 249.
Use 9 as the next digit of our solution. 
Result so far: 119814.15169
If we take 6111 away from 6360, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 14:
The number 679 fits into 2490 3 times, leaving a remainder of 453.
Write down 3 as next digit of the result. 
Result so far: 119814.151693
The remainder is 453 after subtracting 2037 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Advancing to step 15:
679 can be fit into 4530 6 times, resulting in a remainder of 456.
Put 6 as the next digit of the answer. 
Result so far: 119814.1516936
Subtract 4074 from 4530 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 16:
If we divide 4560 by 679, we get 6 and a remainder of 486.
The number 6 becomes the next digit in our result. 
Result so far: 119814.15169366
If we subtract 4074 from 4560, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

After the division, we end up with 119814.15169366 and a remainder of 4.86e-07.
