71223909 divided by 813 
Our goal is to divide 71223909 by 813.

Going ahead to step 1:
When dividing 7 by 813, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 813

Step 2:
If we divide 71 by 813, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 813

Advancing to step 3:
813 can be fit into 712 0 times, resulting in a remainder of 712.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 712 leaves us with 712.
Include the next digit (2) from the dividend after 712, then repeat: 7122 / 813

On to step 4:
The number 813 fits into 7122 8 times, leaving a remainder of 618.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 6504 from 7122 and we're left with 618.
Include the next digit (3) from the dividend after 618, then repeat: 6183 / 813

Step 5:
6183 divided by 813 is 7 with a remainder of 492.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Deduct 5691 from 6183 and we're left with 492.
Grab the next digit (9) from the dividend, add it to 492, then carry on: 4929 / 813

Step 6:
813 goes into 4929 6 times with a remainder of 51.
The next digit of our result is 6. 
Result so far: 876.0
If we subtract 4878 from 4929, we get 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 813

Advancing to step 7:
813 can be fit into 510 0 times, resulting in a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 8760.0
The remainder is 510 after subtracting 0 from 510.
Take the next digit (9) from the dividend and append it to 510, then repeat: 5109 / 813

Let's proceed to step 8:
The number 813 fits into 5109 6 times, leaving a remainder of 231.
Put 6 as the next digit of the answer. 
Result so far: 87606.0
Subtract 4878 from 5109 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 9:
2310 divided by 813 is 2 with a remainder of 684.
The number 2 becomes the next digit in our result. 
Result so far: 87606.2
Subtracting 1626 from 2310 leaves us with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Going ahead to step 10:
6840 divided by 813 is 8 with a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 87606.28
If we subtract 6504 from 6840, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 11:
813 can be fit into 3360 4 times, resulting in a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 87606.284
Subtract 3252 from 3360 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 12:
If we divide 1080 by 813, we get 1 and a remainder of 267.
Put 1 as the next digit of the answer. 
Result so far: 87606.2841
If we take 813 away from 1080, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 13:
813 goes into 2670 3 times with a remainder of 231.
Put 3 as the next digit of the answer. 
Result so far: 87606.28413
Subtract 2439 from 2670 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 14:
813 goes into 2310 2 times with a remainder of 684.
The number 2 becomes the next digit in our result. 
Result so far: 87606.284132
If we subtract 1626 from 2310, we get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 15:
6840 divided by 813 is 8 with a remainder of 336.
The next digit of our result is 8. 
Result so far: 87606.2841328
Deduct 6504 from 6840 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 16:
When dividing 3360 by 813, we get 4 with a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 87606.28413284
The remainder is 108 after subtracting 3252 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

After the division, we end up with 87606.28413284 and a remainder of 1.08e-07.
