We divide 81910062 by 618
We want to figure out the number of times 81910062 can be divided by 618.

Advancing to step 1:
The number 618 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 618

Let's proceed to step 2:
The number 618 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 618

On to step 3:
When dividing 819 by 618, we get 1 with a remainder of 201.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 618 from 819 and we're left with 201.
Fetch the next digit (1) from the dividend, attach it to 201 and continue: 2011 / 618

Moving on to step 4:
When dividing 2011 by 618, we get 3 with a remainder of 157.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1854 from 2011, we get 157.
Append the next digit (0) from the dividend to 157 and continue with: 1570 / 618

On to step 5:
1570 divided by 618 is 2 with a remainder of 334.
Write down 2 as next digit of the result. 
Result so far: 132.0
Subtract 1236 from 1570 to get 334.
Append the next digit (0) from the dividend to 334 and continue with: 3340 / 618

On to step 6:
If we divide 3340 by 618, we get 5 and a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 1325.0
If we subtract 3090 from 3340, we get 250.
Take the next digit (6) from the dividend and append it to 250, then repeat: 2506 / 618

Moving on to step 7:
618 can be fit into 2506 4 times, resulting in a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 13254.0
Subtracting 2472 from 2506 leaves us with 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 618

Moving on to step 8:
618 goes into 342 0 times with a remainder of 342.
Put 0 as the next digit of the answer. 
Result so far: 132540.0
If we take 0 away from 342, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 9:
618 goes into 3420 5 times with a remainder of 330.
Write down 5 as next digit of the result. 
Result so far: 132540.5
The remainder is 330 after subtracting 3090 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
When dividing 3300 by 618, we get 5 with a remainder of 210.
The next digit of our result is 5. 
Result so far: 132540.55
Deduct 3090 from 3300 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The quotient of the division is 132540.55, and the remainder is 0.21.
