81518830 divided by 470 
We want to figure out the number of times 81518830 can be divided by 470.

Step 1:
The number 470 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.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 470

Going ahead to step 2:
The number 470 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 470

Going ahead to step 3:
If we divide 815 by 470, we get 1 and a remainder of 345.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 470 from 815 and we're left with 345.
Include the next digit (1) from the dividend after 345, then repeat: 3451 / 470

Moving on to step 4:
470 can be fit into 3451 7 times, resulting in a remainder of 161.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 3290 away from 3451, we end up with 161.
Include the next digit (8) from the dividend after 161, then repeat: 1618 / 470

Advancing to step 5:
1618 divided by 470 is 3 with a remainder of 208.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
Deduct 1410 from 1618 and we're left with 208.
Append the next digit (8) from the dividend to 208 and continue with: 2088 / 470

Let's proceed to step 6:
470 can be fit into 2088 4 times, resulting in a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 1734.0
The remainder is 208 after subtracting 1880 from 2088.
Fetch the next digit (3) from the dividend, attach it to 208 and continue: 2083 / 470

On to step 7:
470 goes into 2083 4 times with a remainder of 203.
Put 4 as the next digit of the answer. 
Result so far: 17344.0
Subtract 1880 from 2083 to get 203.
Fetch the next digit (0) from the dividend, attach it to 203 and continue: 2030 / 470

On to step 8:
If we divide 2030 by 470, we get 4 and a remainder of 150.
Record the quotient 4 as the next digit in the result. 
Result so far: 173444.0
Subtracting 1880 from 2030 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 9:
1500 divided by 470 is 3 with a remainder of 90.
The next digit of our result is 3. 
Result so far: 173444.3
If we take 1410 away from 1500, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
The number 470 fits into 900 1 times, leaving a remainder of 430.
Use 1 as the next digit of our solution. 
Result so far: 173444.31
The remainder is 430 after subtracting 470 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 11:
4300 divided by 470 is 9 with a remainder of 70.
The next digit of our result is 9. 
Result so far: 173444.319
Deduct 4230 from 4300 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
700 divided by 470 is 1 with a remainder of 230.
The number 1 becomes the next digit in our result. 
Result so far: 173444.3191
If we subtract 470 from 700, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 13:
If we divide 2300 by 470, we get 4 and a remainder of 420.
The next digit of our result is 4. 
Result so far: 173444.31914
If we take 1880 away from 2300, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 14:
470 can be fit into 4200 8 times, resulting in a remainder of 440.
Write down 8 as next digit of the result. 
Result so far: 173444.319148
Subtract 3760 from 4200 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 15:
When dividing 4400 by 470, we get 9 with a remainder of 170.
Record the quotient 9 as the next digit in the result. 
Result so far: 173444.3191489
Subtract 4230 from 4400 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 16:
470 goes into 1700 3 times with a remainder of 290.
The next digit of our result is 3. 
Result so far: 173444.31914893
If we take 1410 away from 1700, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The quotient of the division is 173444.31914893, and the remainder is 2.9e-07.
