We look at the division of 80101423 by 570 
We want to figure out the number of times 80101423 can be divided by 570.

On to step 1:
570 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 570

Advancing to step 2:
570 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 570

Step 3:
570 can be fit into 801 1 times, resulting in a remainder of 231.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 570 from 801 to get 231.
Grab the next digit (0) from the dividend, add it to 231, then carry on: 2310 / 570

On to step 4:
2310 divided by 570 is 4 with a remainder of 30.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 2280 from 2310, we get 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 570

Step 5:
The number 570 fits into 301 0 times, leaving a remainder of 301.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Subtracting 0 from 301 leaves us with 301.
Grab the next digit (4) from the dividend, add it to 301, then carry on: 3014 / 570

Going ahead to step 6:
3014 divided by 570 is 5 with a remainder of 164.
The next digit of our result is 5. 
Result so far: 1405.0
Deduct 2850 from 3014 and we're left with 164.
Bring next digit (2) of the dividend behind the 164 and repeat the process: 1642 / 570

Advancing to step 7:
570 can be fit into 1642 2 times, resulting in a remainder of 502.
Record the quotient 2 as the next digit in the result. 
Result so far: 14052.0
Subtract 1140 from 1642 to get 502.
Bring next digit (3) of the dividend behind the 502 and repeat the process: 5023 / 570

Going ahead to step 8:
570 can be fit into 5023 8 times, resulting in a remainder of 463.
Use 8 as the next digit of our solution. 
Result so far: 140528.0
The remainder is 463 after subtracting 4560 from 5023.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Going ahead to step 9:
The number 570 fits into 4630 8 times, leaving a remainder of 70.
The next digit of our result is 8. 
Result so far: 140528.8
The remainder is 70 after subtracting 4560 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
570 can be fit into 700 1 times, resulting in a remainder of 130.
Write down 1 as next digit of the result. 
Result so far: 140528.81
Subtract 570 from 700 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 11:
When dividing 1300 by 570, we get 2 with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 140528.812
The remainder is 160 after subtracting 1140 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
When dividing 1600 by 570, we get 2 with a remainder of 460.
Put 2 as the next digit of the answer. 
Result so far: 140528.8122
If we subtract 1140 from 1600, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

After the division, we end up with 140528.8122 and a remainder of 0.0046.
