81051855 ÷ 618 
We're looking to find how many times 618 goes into 81051855.

On to step 1:
618 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 618

Moving on to step 2:
618 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 618

Moving on to step 3:
618 goes into 810 1 times with a remainder of 192.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 618 from 810 to get 192.
Grab the next digit (5) from the dividend, add it to 192, then carry on: 1925 / 618

Moving on to step 4:
If we divide 1925 by 618, we get 3 and a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1854 from 1925 to get 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 618

Step 5:
The number 618 fits into 711 1 times, leaving a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 131.0
The remainder is 93 after subtracting 618 from 711.
Include the next digit (8) from the dividend after 93, then repeat: 938 / 618

On to step 6:
618 goes into 938 1 times with a remainder of 320.
Put 1 as the next digit of the answer. 
Result so far: 1311.0
The remainder is 320 after subtracting 618 from 938.
Include the next digit (5) from the dividend after 320, then repeat: 3205 / 618

Moving on to step 7:
The number 618 fits into 3205 5 times, leaving a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 13115.0
Subtract 3090 from 3205 to get 115.
Take the next digit (5) from the dividend and append it to 115, then repeat: 1155 / 618

Moving on to step 8:
618 can be fit into 1155 1 times, resulting in a remainder of 537.
Use 1 as the next digit of our solution. 
Result so far: 131151.0
Deduct 618 from 1155 and we're left with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

On to step 9:
5370 divided by 618 is 8 with a remainder of 426.
The number 8 becomes the next digit in our result. 
Result so far: 131151.8
If we take 4944 away from 5370, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Advancing to step 10:
618 goes into 4260 6 times with a remainder of 552.
Write down 6 as next digit of the result. 
Result so far: 131151.86
Subtract 3708 from 4260 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 11:
618 goes into 5520 8 times with a remainder of 576.
Use 8 as the next digit of our solution. 
Result so far: 131151.868
If we take 4944 away from 5520, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 12:
5760 divided by 618 is 9 with a remainder of 198.
Record the quotient 9 as the next digit in the result. 
Result so far: 131151.8689
If we subtract 5562 from 5760, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 13:
If we divide 1980 by 618, we get 3 and a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 131151.86893
If we subtract 1854 from 1980, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 14:
618 goes into 1260 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 131151.868932
The remainder is 24 after subtracting 1236 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 15:
The number 618 fits into 240 0 times, leaving a remainder of 240.
The next digit of our result is 0. 
Result so far: 131151.868932
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 16:
618 goes into 2400 3 times with a remainder of 546.
Record the quotient 3 as the next digit in the result. 
Result so far: 131151.86893203
If we subtract 1854 from 2400, we get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

The final outcome is 131151.86893203, with a leftover of 5.46e-07.
