57572543 ÷ 801 
We want to figure out the number of times 57572543 can be divided by 801.

Let's proceed to step 1:
801 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 801

Moving on to step 2:
If we divide 57 by 801, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 801

Going ahead to step 3:
801 can be fit into 575 0 times, resulting in a remainder of 575.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 575 leaves us with 575.
Take the next digit (7) from the dividend and append it to 575, then repeat: 5757 / 801

On to step 4:
801 goes into 5757 7 times with a remainder of 150.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 5607 from 5757 leaves us with 150.
Fetch the next digit (2) from the dividend, attach it to 150 and continue: 1502 / 801

Let's proceed to step 5:
801 can be fit into 1502 1 times, resulting in a remainder of 701.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 801 from 1502, we get 701.
Fetch the next digit (5) from the dividend, attach it to 701 and continue: 7015 / 801

Step 6:
When dividing 7015 by 801, we get 8 with a remainder of 607.
The number 8 becomes the next digit in our result. 
Result so far: 718.0
If we take 6408 away from 7015, we end up with 607.
Fetch the next digit (4) from the dividend, attach it to 607 and continue: 6074 / 801

Moving on to step 7:
When dividing 6074 by 801, we get 7 with a remainder of 467.
Put 7 as the next digit of the answer. 
Result so far: 7187.0
Subtracting 5607 from 6074 leaves us with 467.
Fetch the next digit (3) from the dividend, attach it to 467 and continue: 4673 / 801

Advancing to step 8:
The number 801 fits into 4673 5 times, leaving a remainder of 668.
Use 5 as the next digit of our solution. 
Result so far: 71875.0
Subtracting 4005 from 4673 leaves us with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Advancing to step 9:
The number 801 fits into 6680 8 times, leaving a remainder of 272.
Use 8 as the next digit of our solution. 
Result so far: 71875.8
If we subtract 6408 from 6680, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 10:
2720 divided by 801 is 3 with a remainder of 317.
Write down 3 as next digit of the result. 
Result so far: 71875.83
The remainder is 317 after subtracting 2403 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 11:
3170 divided by 801 is 3 with a remainder of 767.
Record the quotient 3 as the next digit in the result. 
Result so far: 71875.833
Deduct 2403 from 3170 and we're left with 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

The final outcome is 71875.833, with a leftover of 0.0767.
