We're dividing 57773650 by 809 
We want to figure out the number of times 57773650 can be divided by 809.

Moving on to step 1:
5 divided by 809 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 809

Advancing to step 2:
809 can be fit into 57 0 times, resulting in a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 809

Step 3:
When dividing 577 by 809, we get 0 with a remainder of 577.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 577 leaves us with 577.
Fetch the next digit (7) from the dividend, attach it to 577 and continue: 5777 / 809

Advancing to step 4:
When dividing 5777 by 809, we get 7 with a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 5663 from 5777 to get 114.
Bring next digit (3) of the dividend behind the 114 and repeat the process: 1143 / 809

Step 5:
The number 809 fits into 1143 1 times, leaving a remainder of 334.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Deduct 809 from 1143 and we're left with 334.
Take the next digit (6) from the dividend and append it to 334, then repeat: 3346 / 809

On to step 6:
The number 809 fits into 3346 4 times, leaving a remainder of 110.
Record the quotient 4 as the next digit in the result. 
Result so far: 714.0
If we subtract 3236 from 3346, we get 110.
Bring next digit (5) of the dividend behind the 110 and repeat the process: 1105 / 809

Advancing to step 7:
The number 809 fits into 1105 1 times, leaving a remainder of 296.
The next digit of our result is 1. 
Result so far: 7141.0
Subtract 809 from 1105 to get 296.
Fetch the next digit (0) from the dividend, attach it to 296 and continue: 2960 / 809

Let's proceed to step 8:
809 goes into 2960 3 times with a remainder of 533.
Write down 3 as next digit of the result. 
Result so far: 71413.0
Subtracting 2427 from 2960 leaves us with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Let's proceed to step 9:
5330 divided by 809 is 6 with a remainder of 476.
The number 6 becomes the next digit in our result. 
Result so far: 71413.6
Subtracting 4854 from 5330 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 10:
If we divide 4760 by 809, we get 5 and a remainder of 715.
Use 5 as the next digit of our solution. 
Result so far: 71413.65
Subtract 4045 from 4760 to get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Going ahead to step 11:
The number 809 fits into 7150 8 times, leaving a remainder of 678.
The number 8 becomes the next digit in our result. 
Result so far: 71413.658
If we subtract 6472 from 7150, we get 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Step 12:
If we divide 6780 by 809, we get 8 and a remainder of 308.
Put 8 as the next digit of the answer. 
Result so far: 71413.6588
If we subtract 6472 from 6780, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The quotient of the division is 71413.6588, and the remainder is 0.00308.
