We're dividing 71818450 by 810 
We're looking to find how many times 810 goes into 71818450.

Going ahead to step 1:
7 divided by 810 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 810

Advancing to step 2:
The number 810 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 810

Let's proceed to step 3:
When dividing 718 by 810, we get 0 with a remainder of 718.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 718 to get 718.
Take the next digit (1) from the dividend and append it to 718, then repeat: 7181 / 810

Going ahead to step 4:
810 can be fit into 7181 8 times, resulting in a remainder of 701.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 6480 away from 7181, we end up with 701.
Bring next digit (8) of the dividend behind the 701 and repeat the process: 7018 / 810

Moving on to step 5:
810 can be fit into 7018 8 times, resulting in a remainder of 538.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtracting 6480 from 7018 leaves us with 538.
Grab the next digit (4) from the dividend, add it to 538, then carry on: 5384 / 810

Going ahead to step 6:
5384 divided by 810 is 6 with a remainder of 524.
The number 6 becomes the next digit in our result. 
Result so far: 886.0
If we subtract 4860 from 5384, we get 524.
Take the next digit (5) from the dividend and append it to 524, then repeat: 5245 / 810

Moving on to step 7:
If we divide 5245 by 810, we get 6 and a remainder of 385.
Record the quotient 6 as the next digit in the result. 
Result so far: 8866.0
Subtract 4860 from 5245 to get 385.
Grab the next digit (0) from the dividend, add it to 385, then carry on: 3850 / 810

Let's proceed to step 8:
If we divide 3850 by 810, we get 4 and a remainder of 610.
Record the quotient 4 as the next digit in the result. 
Result so far: 88664.0
Subtracting 3240 from 3850 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 9:
When dividing 6100 by 810, we get 7 with a remainder of 430.
Use 7 as the next digit of our solution. 
Result so far: 88664.7
Subtract 5670 from 6100 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 10:
When dividing 4300 by 810, we get 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 88664.75
Subtracting 4050 from 4300 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 11:
If we divide 2500 by 810, we get 3 and a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 88664.753
If we take 2430 away from 2500, we end up 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:
If we divide 700 by 810, we get 0 and a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 88664.753
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 13:
The number 810 fits into 7000 8 times, leaving a remainder of 520.
The next digit of our result is 8. 
Result so far: 88664.75308
Subtracting 6480 from 7000 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 14:
810 can be fit into 5200 6 times, resulting in a remainder of 340.
Record the quotient 6 as the next digit in the result. 
Result so far: 88664.753086
If we take 4860 away from 5200, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 15:
3400 divided by 810 is 4 with a remainder of 160.
Write down 4 as next digit of the result. 
Result so far: 88664.7530864
If we subtract 3240 from 3400, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
The number 810 fits into 1600 1 times, leaving a remainder of 790.
Use 1 as the next digit of our solution. 
Result so far: 88664.75308641
If we subtract 810 from 1600, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

After the division, we end up with 88664.75308641 and a remainder of 7.9e-07.
