We look at the division of 81645979 by 618 
Let's see how many times 618 fits into 81645979.

Let's proceed to step 1:
8 divided by 618 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 618

Moving on to step 2:
81 divided by 618 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 618

Advancing to step 3:
618 can be fit into 816 1 times, resulting in a remainder of 198.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 198 after subtracting 618 from 816.
Fetch the next digit (4) from the dividend, attach it to 198 and continue: 1984 / 618

Going ahead to step 4:
When dividing 1984 by 618, we get 3 with a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1854 from 1984 to get 130.
Fetch the next digit (5) from the dividend, attach it to 130 and continue: 1305 / 618

Going ahead to step 5:
618 goes into 1305 2 times with a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Subtracting 1236 from 1305 leaves us with 69.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 618

Moving on to step 6:
618 goes into 699 1 times with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 1321.0
If we take 618 away from 699, we end up with 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 618

Step 7:
618 goes into 817 1 times with a remainder of 199.
Use 1 as the next digit of our solution. 
Result so far: 13211.0
Subtract 618 from 817 to get 199.
Take the next digit (9) from the dividend and append it to 199, then repeat: 1999 / 618

Moving on to step 8:
618 can be fit into 1999 3 times, resulting in a remainder of 145.
The number 3 becomes the next digit in our result. 
Result so far: 132113.0
Deduct 1854 from 1999 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 9:
If we divide 1450 by 618, we get 2 and a remainder of 214.
Use 2 as the next digit of our solution. 
Result so far: 132113.2
If we take 1236 away from 1450, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 10:
When dividing 2140 by 618, we get 3 with a remainder of 286.
Write down 3 as next digit of the result. 
Result so far: 132113.23
The remainder is 286 after subtracting 1854 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 11:
618 goes into 2860 4 times with a remainder of 388.
The number 4 becomes the next digit in our result. 
Result so far: 132113.234
If we take 2472 away from 2860, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 12:
3880 divided by 618 is 6 with a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 132113.2346
The remainder is 172 after subtracting 3708 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 13:
618 goes into 1720 2 times with a remainder of 484.
The next digit of our result is 2. 
Result so far: 132113.23462
Subtract 1236 from 1720 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 14:
618 can be fit into 4840 7 times, resulting in a remainder of 514.
Record the quotient 7 as the next digit in the result. 
Result so far: 132113.234627
Deduct 4326 from 4840 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Step 15:
618 goes into 5140 8 times with a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 132113.2346278
Subtract 4944 from 5140 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 16:
When dividing 1960 by 618, we get 3 with a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 132113.23462783
Deduct 1854 from 1960 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Our division results in 132113.23462783 with a remaining 1.06e-07.
